Jharkhand has been identified for preparation of Soil mapping and creation of soil database.

ADCC Infocad was empanelled as a consultant to execute the project and the present report is

on Dumka district, which is one of those 06 districts from Santhal Paragana province of

Jharkhand State.

The Dumka district is present on the North-East part of the Jharkhand state. District

experience average rainfall of 1378.70 mm and covering area of 3703.13 Sq.Km. Rivers like

Bansoi, Matihara, Tepra, Mayurakshi, Brahmani, Nunbil and Sidhisari flowing from different of

the district boundary. Dumka has one major sub-division as Dumka. This division is

administratively divided in to 10 blocks. Agriculture is the main occupation of the district with

paddy is grown as major crop. Physiographical terrain shows maximum contour height as 400

Mtr and minimum 20 Mtrs.

In Dumka district base rock is Gneisses over which Rajmahal traps constitutes basaltic

lava flows with intertrapian beds are present. Rajmahal traps are overlaid by alluvium on the

top. This alluvium consists of sand and clay. Metamorphic gneisses are present in major

quantity in the district. In the alluvium area agriculture development is good because of the rich

available water resource but on the East part of the district soil is not much developed and

therefore agriculture is mainly on the rainfed type.

therefore agriculture is mainly on the rainfed type.

The soil mapping carried out for Dumka district indicates that in all 31 soil series have been

mapped with 24 associations. Out of which 09 mapping units and 15 series have presence on

Gneisses. 03 mapping units and 5 series fall on Gondwanas sedimentary formation and 12

mapping units and 11 series fall on Rajmahal Traps. 01 mapping unit falls on Gullied land.





Degraded status of the Dumka district is studied where it is found that sloping

hills are very near to the East corner and sporadic patched in NE part of the district.

Because of high slope there are more likely chances that fertile soil will get eroded.

i.exe

Such area is confined to about 12.01 % of the district geographical area. This erosion

needs to be protected by soil conservation practices. Soil pH is also on the acidic type

throughout the district. Out of 31 series 25 series are found to be acidic and 05 are near to

neutral state and 01 is Alkaline in nature.

In all district 05 land capability classes are identified depending on the physical

characteristics. Soils in 75.94 % of the geographical area of district are classified in class II

indicating good state of soil condition. Land capability class VIII is with very few area 7.82%

covering forest. Therefore forest conservation practices in this area are urgently needed.

In district 03 types of land irrigability classes could be identified viz 2, 5 and 6, out of

which 76.08% of the area is under Class 2 showing moderately suitable aerable lands. Class 5

is with only 2.45 % of Area. Class 6 is with 17.89% of the area and balance 3.57% is for

unclassified units.

Dumka district is having monocrop culture of cropping pattern however the land

irrigability class II shows 75.94 % of the geographical area indicating good potential of area to

develop double cropping. District also have potential for horticulture cultivation in addition to this

other sectors such as prawns farming, aquaculture is also recommended using inland water

system.

Finally socioeconomic condition of the district is poor since female literacy rate is low

32.68%, which creates health hazards. The numbers of primary schools are less 1093 and

middle schools are only 195 as compared to the area of the district.

Water harvesting in form of bunds, gulley plugs are recommended in East and NE part

of the district.

Chapter-1 INTRODUCTION

Soil resource mapping for any state is very important activity since it is directly related to the

overall development of the state. Jharkhand Space Application Centre, Ranchi, Department of

Information technology Jharkhand invited tender for the preparation of the soil map with the help

of satellite image interpretation and field surveys. These thematic maps are prepared for use in

planning agriculture production and soil conservation. The basic use of this thematic mapping is

to understand the spatial distribution of different type of soil, also to identify soil related

problems in area which would be useful for addressing these problems for future needs.

Soil conservation has become a necessary step to preserve the fertile soil, which otherwise gets

eroded with time. Land provides food, fuel, fodder and shelter to the mankind besides

supporting secondary and other economic life supporting system. Due to over utilization of this

resource over long period cause degradation of soil quality which needs to be restored by

adopting appropriate conservation practices. Nature takes almost 600-1000 years to build 2.5

cm of topsoil but this very topsoil get displaced in a year due to unplanned activities or non

conservation.

The generation of information on types, extents, distribution and characteristics of soil of an

area as well as their potential and problems are vital for appropriate decision on their rational

use for sustainable agriculture production without any risk of soil degradation.

The demographic pressure is rapidly mounting on the natural resources. The present population

of India is 1050 million which is estimated to become 1.4 billion by 2025 and 1.7 billion by 2050

AD needing annually about 380 MT and 480 MT food grains respectively. Under the situation

heavy biotic pressure on land is expected, which may cause land degradation in terms of

productivity. The situation therefore calls for judicious soil management practices and thus

systematic soil mapping is indispensible.

Soil is called to be non-elastic, non renewable asset. The per capita availability of land that

decreased from 0.5 ha in 1950-51 to 0.15 ha in 1999-2000 and it is likely to decrease further to

0.08 ha in 2020 due to rise in population in geometric proportion. As a result land holding

capacity will decrease further which would result in low production of food grains. In order to

achieve the food security in situation of increasing population it is necessary to manage the soil

resources on sustainable basis through adoption of modern technological inputs. The

7

management of land resources is possible with the help of soil inventory prepared in these

project activities. This soil data will definitely help in production and steps to be taken for the

conservation of this non renewable asset

Realising the importance of soil resource the Jharkhand Space Applications Centre

conceptualized a project for preparation of soil map on 1:50000 scale using IRS satellite

images. In view of this a project of soil mapping for six districts covering Santhal Paragana

province has been awarded to ADCC Infocad Nagpur. Accordingly ADCC Infocad Nagpur has

prepared soil maps as per the methodology designed by the Jharkhand Space Applications

Centre.

The present project on the soil mapping of Dumka district of Jharkhand has been aimed towards

the following

Preparation of soil map on 1:50000 scale

Interpretation and evaluation of database on soils.

Identification of potential soil and there related problems.

Suggestive strategy and approaches for optimum utilization of soil and waste land area.

Chapter-2 GEOGRAPHICAL SETTING

2.1 Location and Extent

Dumka district is spread out in an area of 3703.13 Sq.km in the NE part of Jharkhand state. The

district lies between 86016’ North Latitude to 87015’ East Longitude. District is surrounded by

Deoghar on North-West direction, Godda district on North, Pakur on NE and West Bengal on

SE. The population of the district is 1102217 as per 2001 Census.

2.2 Physiography and Relief

Dumka is predominantly a hilly terrain district with numbers of drainages. Entire district is with

high ridges and valleys. Hills are mostly present on the NE, SE and South side of the district.

Because of the hilly terrain erosion is on higher side result in to low fertility of soil and high

acidic character.

2.3 Drainage

The main drainages of the district are Pathro Nadi and Ajay River present at the Central part of

the district and flowing towards SE direction.

Name of Drainage Location on District Flowing from

Bansoi Nadi North-East West to East

Matihara Nadi Central NW-SE

Tepra Nadi West NW-South

Mayurakshi or Mor Nadi Central N-S

Brahmani Nadi East West- East

Nunbil Nadi South North-South

Sidhisari Nadi South West to East

2.4 Climate

Jharkhand has a different climate from that of Bihar and other neighboring state. Monsoon

winds come from two different areas. One section comes from Bay of Bengal and other section 9

from Arabian Sea. Wind from the Bay of Bengal contains more moisture as Jharkhand state is

more near to the former part. The temperature of the state is also on the lower side because of

its height from sea level. About 1/3rd of the area has elevation of 400 mt and rest 2/3rd has

height of only 300 mt from MSL. As a result the temperature of Jharkhand is 60 F less than the

Ganges plain. The elevation also affects the pressure of wind.

Jharkhand has three main seasons.

Summer Season March to May

Rainy Season June to October

Winter Season November to February

The summer season:

The period of this season is from 16th March to 15th June. The higher elevation and the forest

cover is responsible for reduction of temperature in some areas. During summer many parts of

the state also experience dust storm, thunderstorm and showers. The average rainfall during

summer varies from 50mm to 850 mm. Santhal Paragana province receives 152 mm of rain

The rainy season:

The period of this season is from June to October but monsoon reaches Jharkhand by middle of

June. This state gets relatively more rain than Ganga plains. Average rainfall of the state is

1200 mm but the heaviest rainfall is recorded in Pat region because of higher elevation. SW-

Part also receives higher rainfall because of greater forest cover. According to one observation

the North-Koel basin receives rainfall between 1200mm to 1250 mm but the SW portion of state

gets 1350mm to 1450 mm.

The winter Season

This winter season extends between November and February. In winter season state has, clear

and charming weather with blue sky. The day is warm but the night is cold. December and

January are coldest months with temperature comes to 50 C to 70 C. Jharkhand state also gets

10

rainfall in winter. The average rainfall is 50mm but northwest part receives more than 80mm

rainfall.

Jharkhand state is divided in to 07 climatic zones by A. Prasad.

a. North and North Western Zone

b. Central Zone

c. East Santhal Paragana Zone

d. Ocean affected zone

e. South West zone

f. Ranchi Hazaribagh zone

g. Pat Zone

Dumka district comes under East Santhal Paragana zone. This zone includes the geological

formation from Gneisses terrain. The forest area is confined to Eastern as well as NE side of

and south direction of the district.

2.5 Geology

The Dumka district is mostly composed of geological formation of Gneisses rocks. These

Gneissic rocks are present on all the sides except part of South Dumka. Gondwanas rocks are

present on South of the district. Rajmahal traps belonging to lower cretaceous with intertrapian

beds and Gneisses rocks are present in sporadic patches. The Rajmahal traps composed of

basaltic lava flows with massive and vesicular units’ basalt and forms multilayer system.

Rajmahal traps are inter-bedded with intertrapian beds composed of calcareous sediments. The

alluvium composed of clay and sand.

2.6 Natural Vegetation

Forest is a renewable source and contributes substantially to the economic

development. About 29.61% of the state area is under forest. The forest of the state are mainly

located in Santhal Paragana, Chatra, Hazaribagh, Garhwa, and Palamu districts. This Dumka

district is 5% of area covered under the forest. Forest is mostly present in patches in the district.

Because of the human intervention forest has not been spared even on hills. There are a few

reserve forest situated in Dumka district. The vegetations generally traced in Dumka district are

timber species like Shisham, teak, Gamhar, Mahua, Semal. The natural vegetation found in

Jharkhand state is as below.

Chapter 3. AGRICULTURE, PRESENT LANDUSE AND SOCIOECONOMIC FEATURES

3.1 Land use of Jharkhand

Dumka district is primarily an agricultural district. Out of the total population of 11.02 Lakhs, the

rural population is 10.43 Lakhs and urban population is 0.59 Lakhs. In this way nearly 94.6 % of

the people reside in rural areas. Ref Fig 2.1.Most of them is dependent on agriculture. The total

agricultural land of the Jharkhand state is 29.74 Lakh hectors out of the total area of 79714

Sq.Km. The state needs 46 lakh metric tones but only half of this produced in the state.

Looking at the land use pattern the net sown area of the state is 22.68%. Forest accounts for

29.61%, Uncultivable waste land is 7.19%, Non Agricultural use is 9.89%, Orchards is 1.38%,

pasture 1.10%, and Cultivable waste land is 3.48% and fallow land is 25.01%

Landuse Pattern For Jharkhand State

Harvesting Season

There are three main crop seasons namely Khariff, Rabi and summer. Major Khariff crops are

maize, bajara, vegetable, til etc. Harvesting season of these crops is September-October. Like

Khariff crops Aghani crops are also grown in state. They are sown in beginning of monsoon just

like Khariff crops but the harvesting season is January-February.

3.2 Crops of Dumka

Paddy is the main crop of Jharkhand as well as Dumka. It is grown as Aghani, Bhadai and

Garma crop. The Aghani paddy occupies moderate harvest 63.31%. Following is the table

showing production of Crops in Dumka district.

Pulses like Mung (Kidney Bean) Khesari, Masoor (lentils), and Arhar are grown in the Dumka

district.

Fig 3.2 –Photo from Dumka District

Many area of Jharkhand are beneficial for cultivation of vegetable. It has now been proved

beyond doubt that soil and climate of the region are ideal for production of vegetables like

potato, tomato, cauliflower, cabbage, capsicum. Vegetables are grown in 2.23 Lakh hectors

which produces 33 lakh tones of different vegetables.

The vegetable production in Jharkhand is better. The per capita requirement of vegetable per

day is 280 gms. The state provides 246 gms per capita per day and national production is 230

gms per capita. It is apparent that Jharkhand meets eighty percent of its requirement from its

own vegetable production leaving the gap of only twenty percent.

3.3 Socio-Economic Features

Dumka is the administrative headquarter of the district. The total area of the district is 3703.13

Sq.Km. Ref table no 3.3. Administratively district comprises of one sub-division and ten blocks.

Important statistics of the district are as below.

Table 3.4 Block wise details of Dumka district

Tribani, Kajhia, Sakri, Sundargenia Rivers are flowing through the Dumka district, therefore

agriculture especially paddy cultivation is the main crop. 94% of the population is staying in rural

part of the district with agriculture as a major occupation.

Socio-economic Problems in Dumka

Female literacy rate in the Dumka district is (32.68%) Because of which the other members of

the family are not interested in study and therefore the social development of the family is

halted. Primary schools in the district are (1093) and middle schools are only 195 numbers.

Because of the less literacy in the state the health standard of the Dumka district is seen to be

poor. As per the details from Health organizations, only 25% of the womenfolk in rural Dumka

are coming out for immunization programme. Superstitions are keeping them away from the

health programme. It is very serious issue that 80% of the pregnant woman is suffering from

anemia. This shows a very low profile for the socio-economic condition of the Dumka district.

Chapter 4, METHODOLOGY

Soil survey is commonly used for identification of the soil series, various parameters related to

soil and its conservation. Methods of soil survey are different depending on the requirement of

the project activity. However the end results of the soil survey is generation of soil map and

study of various parameters of the soil. Soil survey results help to obtain description

comprehensively of the research area.

In the earlier period the soil survey used to be carried out by grid pattern and collection of soil

samples in the grid. However the technological advancement in Remote Sensing and

Geographical Information System have been a boom for recent soil survey methods.

Soil survey essentially covers following steps.

Collection of base line data

Interpretation of satellite image

Plan for field survey

Collection of soil samples

Chemical & Mechanical analysis of soil samples

Digitization of various features

Compilation of database

Preperation of final soil maps

18

4.1 Collection of Base line data:

The collection of baseline data in connection of soil mapping project involves collection of

toposheet, satellite images, information related to agriculture and its production, available

geological as well as soil map of the area and other collateral information such as data on

rainfall, temperature etc. Accordingly the toposheet pertaining to study area on 1:50000 were

obtained from survey of India, Ranchi (ref fig No 4.2) and the restricted toposheet which were

not available from Survey of India were referred at Jharkhand Space Applications Centre,

Ranchi. Soil map of study area on 1:500000 scale was obtained from National Bureau of Soil

Survey and Land use Planning, Nagpur. Similarly Geological map of the study area was

obtained from Geological survey of India , as well as from JSAC on 1:250 scale. In additional to

Satellite image data of IRS P6, Liss III (Geocoded Standard FCC) on 1: 50000 scales on hard

as well as soft copy formats were provided by Jharkhand Space Applications centre-Ranchi.

4.2 Interpretation of Satellite image

The soil is a product of parent material, slope, climate i.e. temperature and rainfall. The rainfall

and temperature does not vary to the great extent in a district and thus uniform over a district

area. However there is a variation in geological setup and slope across the district area. Thus

Physiography is a major controlling factor in the formation of soil. The physiographical as well as

slope characters are well reflected in satellite images through image character such as tone

texture, pattern, vegetation and association of features and therefore satellite data of the study

area was visually interpreted based on image character for delineation of different physiographic

units.

Initially standard legend for soil mapping unit was prepared which indicates parent material,

physiographic units and land use following ridge to valley pattern. For example unit the standard

legend of the study area is given in table (Ref table no 4.2). A unique numeric code is given to

geology as well as physiographic units and land use. Thus each mapping unit is represented in

three digits. The first digit indicates the parent material i.e. Geology, Second digit indicates

Physiography and third digit indicates land use.

Standard legend table is prepared for the area of Santhal Paragana province and therefore

geological formation covered in the study area are taken for preparing the standard legend. The

standard legend table is as below in Table No 4.2

The first level interpretation was followed by QS check carried out by expert team of JSAC. The

interpreted boundaries were then finalized incorporating corrections suggested by QS teams.

4.3 Plan for field Survey

A detailed field plan for studying soil profiles of the interpreted mapping units was prepared in

which initially sheet wise units were listed and planning was done in such a manner that

adequate profiles representing all the delineated units were covered. The standard prescribed

by JSAC i.e. 20 profiles / sheet was followed. The soil profiling was done in month of April-to

June 2007. Each profile was dug to standard size and up a depth of parent material. The size of

profile pit is taken as 90cm in width and 120 cm in length

4.4 Collection of Soil sample

4.4.1 Profile study

The profiles so excavated were studied for soil characters for which a standard form was used.

The different soil layers were demarcated based on consistency and texture. The standard

format is given in annexture-1. This was followed by correlation of profile within the studied

profiles. Thus at the end each unit had 8-10 samples. It was observed that each polygon shows

representation of more than one soil series in which one series is dominant while remaining

series are semi-dominant. Based on this soil association was finalized. The first series represent

dominant soil series while second series represent semi-dominant. The series and association

is given in table no 4.4

4.4.2 Chemical & Mechanical Analysis

The representative samples of each series were then chemically as well as mechanically

analyzed and the observations are given in soil series data. This was followed by field QS check

by JSAC expert committee. This committee scrutinizes each and every sheet thoroughly

particularly for delineation of boundary. The QS committee has also check soil series analytical

data for its chemical and mechanical analysis. The unit boundaries were then finalized duly

incorporating the observation of QS checks.

25

4.5 Digitization of various features

As per the terms of references of the project the soil maps so interpreted were then digitized in

AutoCAD Map / ARC GIS and attribute table as prescribed by JSAC were prepared for soil unit

polygon was prepared. The matching of boundary with the adjacent sheet was maintained.

4.6 Compilation of database

The digitization of the soil map was followed by correlation of series with other vendors and

standardization of output data. The expert committee of JSAC convened a meeting of all

vendors at JSAC in August 2008 in which all the vendors presented soil series data which was

then correlated for standardization of series as well as mapping units. The initial units at

interpretation level were then changed to standard units as prescribed by JSAC expert

committee. Similarly attribute table for each series was then prepared using standard 16 code

digit which indicates series hierarchy and soil characteristics. A standard table of mapping units

and series association with 16 digit code is given below table no 4.3

CHAPTER 5 THE SOILS

5.1 Soil Generalities





The soil map of the total area of Dumka district indicates that 132.30 Sq. km is covered by

townships, water bodies, mines, Sand etc. A major area of 2930.23 Sq.Km of the district is

covered by metamorphic soils while the area of 629.41 Sq.km is covered by Rajmahal trappean

soils. An area of 11.19 Sq.km is covered by Gondwanas soils. The metamorphic soils cover

area lying in all part of the district except Eastern direction. Similarly the Gondwanas soils are

exposed in sporadic patches on Eastern and South-Eastern part of district. Rajmahal traps

occupy total Eastern and SE part of the district.

5.2 Soil –landform relationship

The soil units have good correlation with physiographical units. The mapping unit number 1, 2,

13 and 14 lie on hills and ridges covering an area of 444.7 Sq.km. These soils are severely

eroded since the slope is >15%. These soils are mostly covered by forest cover and are well

drained. While mapping unit 4, 5, 6, and 11 lie on upper Pediplain covering an area of 732.52

Sq.km. These soils are moderately eroded with slopes less than 3%. The land use on the soil is

forest and open scrubs.

Mapping units 3, 10 lie on pediment covering an area of 85.80 Sq.Km

Mapping units 7.8.and 12 are falling on Lower Pedi plain covering an area of 1062.53 Sq.Km.

These soils are also moderately eroded; well drained and major land use on soil is agriculture.

Soil units demarcating Upper Plateau are present on units 15,16,17and 24 covering an area of

234.77 Sq.Km and Lower Plateau in soil unit number 18 covering an area of 28.26 Sq.Km. of

Dumka district. Mapping units 9 and 19 falls on valley fills covering an area of 953.46 Sq.Km,

while mapping units 20, 21, 22 and 23 falls on alluvium covering area of 28.75 Sq.km. These

soils have very gentle slope less than 1 %. These soils have none to slight erosion and are also

well drained. The major land use on these soils is intensive agricultural practices.

5.3 Soil distribution and classification

Soil data collected from the field through interpretation, profiling and then chemical / mechanical

analysis were placed as per the standards of soil series formation and integrated in to Arc GIS

format to form the soil map of the district. Soil map of district Dumka shows that hills occupy

North, and NW part. Pediment occupies very small part in the centre of district.. Upper Pediplain

occupies Central part of the district. Lower Pediplain occupies small part on Western and NW

side. Upper plateau occupies Central, Southern and N-E part of district. Lower plateau on

Northern and , Central part. Valley fills on Northern, Central and Western and southern part with

alluvium.

CHAPTER-6 SOIL DEGRADATION STATUS

The soil degradation means loosing the original potential of soil due to various reasons such as

natural causes, increasing biotic pressure due to rise in population, human interference i.e.

unplanned excessive use, loss of top soil cover due to erosion and flooding. The generation of

soil requires very long period may be hundreds of years however the same can be degraded in

a very short time if remained unattended. Thus soil is very important natural resource which is

being exploited by human for various purpose mainly agriculture, forest vegetation, pasture

development etc. The soil is subject to degradation due to natural process as well human

influence. The soil erosion, inundation due to floods etc are the natural causes while excessive

irrigation, intensive farming, heavy use of fertilizers and deforestation are the results of human

influence. Dumka district is one of the backward districts and hence there are no evidences of

land degradation due to human interference because most of the cultivable area is under single

crop and thus lacks intensive farming. The socio-economic situation does not permit excess use

of fertilizers. The area under irrigation is also very low and therefore there are no chances of

land degradation due to excessive irrigation. However the natural causes of soil degradation

such as erosion, and acidic soils have been observed in the district.

6.1 Eroded Soils

The physiographic situation of the district is such that steep sloping hills are lying in the Eastern

as well as SE direction. Therefore the alluvium is found in very low percentage on SE side.

These soils are subject to erosion due to high velocity of water running across the hills.

Therefore the soils on the hills and foothill region are subject to erosion. The soil series namely

Bagnal, Amra, Baramasia, Govindpur and Brindavan (Forest), shows severe to moderate

erosion. The total area under these soils is 444.74 Sq.km i.e. 12.01 % of the geographical area

of the district.

Similarly the district lies in heavy rainfall zone under the situation leaching of bases is expected

which results in formation of acidic soils. The soils in the district are in general acidic in which

the pH ranges from 4.37 to 8.24

37

6.2 Water Logging soils

Since Major River like Ganges is not present in the Dumka district, the percentage of the water

logged area is not present. The percentage of alluvium is also very less (0.78% of total area)

6.3 Acidic Soils

The physiographic and rainfall situation of the district favors heavy leaching of the bases from

the top soil causing formation of acidic soils and as a result the soils of the district are in general

acidic as well as alkaline where the pH ranges from 4.37 to 8.24. Out of the 31 series in the

district 25 series are acidic in nature and 05 series are Neutral in nature and 01 is alkaline in

nature.

6.4 Gullied lands

Areas measuring 37.09 Sq.Km in sporadic patches along the banks of streams are observed to

be gullied lands. However the extent is less.

6.5 Deforestation

The total forest area in the district is 12.01 Sq.Km confining to hills covering NE, and SE and

south parts of the district however the forest is surrounded by open forest. This area shows

degraded forest cover at many locations is present as a result of rampant deforestation activity.

The series Baramasia, Brindavan forest are major soil series. The soils are also prone to

erosion due to steep slopes. Although as per the database of Ministry of forest and

Environment Jharkhand about 29.17 % of forest land is available in district recent images shows

a different figures. (Reference - Page 126 inside Jharkhand- Sources Ministry of Forest).

38

Chapter-7 Interpretation of Soils for Land Resources Management

The soil map should be interpreted in a way which will be meaningful to the ultimate users. Soil

maps can be interpreted by the individual kinds of soils and by the grouping of soils. Such

interpretations provide the user with all the information that can be obtained from a map. The

kind of soil grouped and the variation permitted within each group differ according to the use to

be made of the grouping.

7.1 Land Capability Classification

The land capability classification is one of such important interpretative groupings. The

capability classification of land also begins with the individual soil mapping units. In this

classification the aerable soils are grouped according to their potentialities and limitations for

sustained production of commonly cultivated crops and the non-aerable soils (Soils unsuited for

longtime sustained use of cultivated crops) are grouped according to their potential and

limitations for the production of permanent vegetation.

Land Capability Classes

The land capability classification places all the soils in eight capability classes. The risk of soil

damage or limitation in use, become progressively greater from class I to Class VIII. Soils in the

first four classes under good management are capable of producing adapted plants such as

forest trees and common cultivated field crops and pastures. Soils in class V, VI and VII are

suited to use of adapted native plants. Some soils in classes V and VI are also capable of

producing specific crops such as certain fruits and ornamental plants with soils and water

conservation measures. The basic characteristics of capability classes are given below. Class

VIII soils and land forms have limitations that preclude their use for aerable and non-aerable

crops.

(a) Land suited to cultivation and other users.

Class-I Soils have few limitations that restrict their use.

Class-II Soils have some limitations that reduce the choices of plants or require moderate

conservation practices.

39

Class-III Soils have severe limitations that reduce the choice of plats or require special

conservation practices.

Class IV Soils have very severe limitations that restrict the choice of plants or require very

careful management or both.

(b) Land limited in use-generally not suited to cultivation

Class V Soils have little or no erosion hazard but have other limitations impractical to

remove limiting use to pasture woodland or wildlife food and cover.

Class VI Soils have severe limitations making them unsuited to cultivation and limit their

use largely to pasture woodland or wild life food and cover.

Class VII Soils have severe limitations making them unsuited to cultivation and restrict their

use to grazing, woodland or wild life.

Class VIII Soils and landforms have limitations that preclude their use for arable or non-

arable crops and restrict their use to recreation, wild life or water supply or to

aesthetic purposes.

Land Capability classes of soil association

The soil series in the study area on the basis of physical characters are classified in land

capability classes, II, IV, VI, VII, and VIII of which land capability class II covers major part of the

study area i.e. 75.94 %, Land capability class IV covers 2.45% of the area, while land capability

class VI covers only 3.17 % of the study area. The land capability class VII covers 7.02 % of the

Dumka district. Land capability class VIII covers 7.82% of the study area. The rest of the area

3.57 % is unclassified as covered by settlement, water bodies, rivers, mines etc. The details of

the each land capability class are given below.

Land Capability Class-II

The land capability class II covers soil mapping unit number 5,6,7,8, 9, 12, 18, 19, 10, 21, 22, 23

and 24. The dominant series along with series association and area of each mapping unit is

given in table (Ref Table No 7.1)

Land Characteristics

The land capability class II is associated with soil occurring on alluvial plain, lower plateau and

lower Pediplain. The slope ranging from very gentle to gentle. Occasionally these soils are

40

associated with moderately sloping soils with eroded phase. The soils are prominently under

paddy cultivation however vegetables and fruits are also grown at places.

Soil Characteristics

These soils are deep to very deep with fine loamy texture mostly non-calcareous. Most of the

soils have aquic moisture legend as can be judged from the mottles in the horizon. These soil

belongs to Baran (Typic Haplustepts), Dumka (Typic Ustorthents), Pathlahara(Vertic

Haplustepts), Mohanpur (Typic Haplustepts), Telepara (Typic Haplustepts), Dumkaladak (Typic

Haplustalfs), Patharia(Fluentic Haplustepts), Sarwan (Aquic Haplustepts), Dhababad (Typic

Haplustepts), Banshidharpur (Vertic Haplustepts) , Chandpur (Aquic Haplustepts), Surni mod

(Aquic Haplustepts). These soils are susceptible to slight erosion and therefore needs soil

conservation practices to protect the fertile soil cover. The soils are very fertile and thus can

sustain intensive cropping pattern.

These soils are shallow to moderately deep with fine mixed texture mostly non-calcareous. Most

of the soils have Lithic horizon in the profile and belong to inceptisols however occasionally

associated with entisols. These soils belong to Sahargaon (Typic Haplustepts), Govindpur

(Lithic Haplustepts), and Baramasia (Lithic Ustorthents). These soils are well drained with

moderate to severe erosion and therefore needs soil conservation practices such as contour

bunding or farm bunding to protect the soil cover. The dominant land use is forest. These soils

can be exploited for dry land horticultural crops or for agro-forestry practices.

Dumka (Typic Ustorthents). Sarjori (Typic Haplustepts), Murabari (Typic Ustorthents). These

soils are well drained with moderate erosion and therefore needs soil conservation practices

such as contour bunding or farm bunding to protect the soil cover. The dominant land use is

rainfed paddy. These soils can be exploited for dry land horticultural crops or for agro-forestry

practices.

non-aerable soils and therefore major land use is forest. It is essential to adopt forest

conservation measures. The dominant land use is forest. In order to control the erosion it is

essential to grow grasses on the barren soil covers.

7.2 Land and Soil Irrigability Classification

7.2.1 Land Irrigability Classification

The soils in the study area are classified under different land Irrigability classes based on

limitations of physical and land properties with due consideration to USBR soil Irrigability

classes. These are considered in the three basic headings viz soils (s), topography (t) and

drainage (d). These can be used for denoting sub-classes using the lower case letters s, t, and

44

d. singly or in combination such as st, sd etc. In all there are 06 land suitability classes as given

in below table

Table No 7.6 Land Irrigability and Hydrological Grouping of soils.

Class Suitability / Unsuitability 1 Highly suitable (aerable lands) 2 Moderately suitable (Aerable lands) 3 Marginally suitable (Aerable) lands 4 Suitable for special use or restricted range of crops 5 Unsuitable (non-arable) lands 6 Unsuitable (non-arable) lands

Increasing Productive Capacity

In all two Irrigability classes have been observed which are 2, and 6 of which land Irrigability

class 2 is aerable while class 6 is non aerable The characteristics and series association of

each Irrigability classes observed in the study area are given below.

Land Irrigability class 2

The soil association under land irrigability class II has a moderate suitability for sustained use

under irrigation. These are aerable land. All the units represent sloppy to gently sloping alluvial

plain and lower plateau and Pediplain. The soils associated are moderate to very deep, well

drained and slightly eroded. Clay loams and clays but have a few soil related and topographic

limitation like flooding. Dominant soil unit associated with these are Baran, Dumkaladak,

Patharia, Sarwan, Dhababad, Sarjori and Murabari. These units cover nearly 87.57% of the

study area. These soils are under paddy cultivation as well as orchards and vegetables and

horticultural crops, paddy wheat and gram under rainfed agriculture. These area can be

cultivated for various irrigated crops like sugarcane, fruit crops etc.

Land Irrigability Class 6

The soil association under land Irrigability class VI is non aerable due to limitations of

topography and soil depth. These soils are occurring on hills, foot hills, ridges and plateau top

therefore are shallow in depth and are also severely eroded thus not suitable for sustained use.

These lands are under forest vegetation and the forest is dense to open. The soils associated

are Bagnal, Amra, Khoripania, Dumka, Baramasia, Brindavan Forest and covers 7.79 % of the

geographical area.

7.3 Soil Suitability grouping for sustainable agriculture

The productivity of the soil is linked to inherent characteristics of soil, agro-litho logical setting

and land management. In order to achieve the sustainable development the understanding of

46

local features, potential and problems of soils is very essential, which facilitate appropriate

planning for optimum utilization of aerable as well as non aerable area. Due to rise in

population in geometrical proportion the biotic pressure on land is also increasing as a result the

per capita availability of land is decreasing. The situation calls for judicious soil management

practices to achieve food security of the district. In view of this considering the soil

characteristics of the district following recommendations are made.

Present Scenario of Dumka District

The Dumka district is basically mono crop growing district and paddy is the most dominant crop

in the area. Along with paddy other Khariff crops are also grown like pigeon pea, chick pea. In

addition to these Khariff crops such as wheat, soya bean, maize, and sorgam are also grown in

the district. The cropping intensity of the district is very low as very small percentage agriculture

land is under double crop. The irrigation potential of the district is just 5%. Thus rainfed

agricultural practices are followed in the district. However district does have potential of raising

double crops as area under land capability II is 75.94 % of the geographical area. Similarly soils

of the area are suitable for raising horticultural crops. Based on these following

recommendations are given.

7.3. (a) Under Rainfed Agriculture

A large diversity of cropping system exist under rainfed and dry land agriculture over an over

riding practice of intercropping to cover of risk of single crop failure. Currently under rainfed

conditions only paddy is grown in the district and the land remain fallow during remaining period

of the year. The soils retains considerable amount of moisture after the harvest of wet season

which through proper management can be used for second crop. The best suitable crop rotation

considering the soil potential is recommended as under.

1. Rice – Rice

2. Rice-Wheat

3. Rice-Gram

4. Rice-Maize

7.3. (b) Under Irrigated Agriculture

47

The soils in the district are suitable for irrigation thus in order to increase agricultural

production it is essential to follow irrigation practices. The best possible use of irrigation can

be made by making available limited essential water for protective irrigation and using soil

moisture in combination with irrigation. The irrigation practices along with modern inputs

such as improved seed varieties, fertilizer the yield is expected to be higher i.e. 2.5 times

than the rainfed agricultural practices. Productive soils adequate water, rich natural

biodiversity and agro diversity is expected to enhance food production on unit piece of land.

Two main resources of water are surface water and ground water which needs to be tapped

to increase the agricultural production.

Mostly class II soils in the district can be brought under irrigation system where intensive

farming can be adopted under these programme. The area is suitable for raising cash crop

like sugar cane, vegetable crops, horticulture particularly mango sweet lime etc.

7.4 Cropping system and recommended crops

Currently the predominant crop which is grown in Dumka district is paddy; however other

Khariff crops like maize, pigeon pea, pulses are also gown. Like Khariff crop Aghani crops

are also sown at the time of Khariff crops but the harvesting season is January-February for

Aghani crops. The system demands intensification of crops in space and time dimension.

The length of growing period is the base that decides the make up of cropping system. In

Khariff season the rainfall in terms of quantity and distribution decides the effective cropping

system.

The area mainly belongs to paddy cropping which is permanently rainfed. The land on

succession of ridges and valleys are bunded with 0.5 to 1 Mtrs high bunds depending upon

the type of soil and slope. As a result individual fields are small ranging between0.25 to 0.50

ha. Only small area is under irrigation where paddy is grown after Khariff paddy. The

rotation of crop system is not usually followed.

The area experiences rainfall till late November thus residual moisture after paddy

harvesting and utilized for growing pulses like gram, mug, millets, maize, in rabi season.

Good residual moisture is expected in soils developed over Gangetic plain. The area is

suitable for growing wheat. The Rabi crops invariably should be supported with productive

irrigation through bore wells, lift irrigation through rivers, or canal water to increase the

agriculture production.

48

There is a good scope to utilize inland water resources to produce fresh water prawns to

ensure demand throughout the state and overseas. The state government should undertake

step for development of aquaculture under employment guarantee scheme. It should be an

integral part of developmental programme rather than cropping programme prevailing at

present.

7.5 Horticulture Development

The Dumka district is almost neglected under fruit and vegetable crop cultivation.

Encouragement should be given for product diversification, and value addition. Vegetable

farming needs to develop on commercial scale through the distribution of improved seeds,

planting material and infrastructural facility such market, transport, storage wear house etc.

The major fruit crops which could be profitably cultivated in the district as Mango, Guava,

Jackfruit, Custard apple, Sweet lime, tapioca etc. Thought should be given to organically grown

fruit cultivation. Efforts should also be made to establish vermin-compost unit in each orchard

and readily available biomass such as rice husk, green grass and glarrioda should be used for

composting.

The area is suitable for Vegetable crops like potato, ginger, beans, brinjal, peas, etc. and should

be considered for profitable cultivation.

A very small area (90.75 Sq.Km) of Dumka district is covered by land capability class IV. These

soils are suitable for dry land horticultural activities as most of these soils occur at the foot hill

thus have low moisture regime however dry land horticulture activity if used in conjunction with

traditional Khariff crops to ensure the economical viability of agricultural practices.

Lime treatment

The soils of Dumka district are acidic in nature which needs immediate attention for increasing

production and improving soil structure therefore lime treatment should be invariably given to

the fertile soil of the area. The recommended dose for supply is 1 ton/ Ha for soils where pH

ranges from 4.9 to 6.5 however the lime dose may vary depending upon soil texture.

7.6 Forest forage and grassland development

50

The soils of land capability VI, VII and VIII cover nearly 667 Sq.Km. Most of the soils occur on

hill slopes, thus unsuitable for agricultural practices. However these soils can be productively

utilized for increasing vegetation cover to maintain much needed forest environment. These

areas are suitable for plantation of forest species. This would ensure protection of soil cover

which may deteriorate due to erosion. The plantation activity should be covered with grass

vegetation to ensure fodder for the milk animals in the district.

Following pasture development activity are recommended in Dumka area.

7.7 Hydrological grouping of soils, Water Harvesting, its storage and management.

7.7.1Hydrological soil groups

The hydrological soil groups indicate suitability of soils for sustained irrigation practice for

agriculture product. The grouping is based on soil limitations due to drainage, slope, erosion,

and depth. Soils with none to slight limitations due to erosion and drainage are classified in

group 1. Soils with moderate limitations are classified in group 2. The soils of group 3 have

51

severe limitations and thus unsuitable for irrigation practices. Soils with group 4 are non aerable

and have severe limitation for sustained irrigation. Group 5 soils also have severe limitations for

irrigation due to slope and shallow soil thickness and therefore non aerable.

On the basis of soil characteristics of the soil series of the study area have been classified

under 05 hydrological groups. Those are as under Ref table No-7.10

Hydrological Grouping Definitions 1 None to slight limitations for sustained use under irrigation 2 Moderate soil limitations for sustained use under irrigation 3 Severe soil limitation for sustained use under irrigation 4 Very severe soil limitation for sustained use under irrigation 5 Not suited for irrigation

Hydrological soil group 1 is represented by soil mapping units, 9, 12, 18, 19, 20, 21, 22 and 23.

These soils have very slight limitations and thus are suitable for land irrigation practices. These

soils are suitable for intensive cropping pattern. The soil series namely Sarwan, Dhababad,

Pathlahara, Banshidharpur, Mohanpur, Mitial, and Chandpur are associated with this

hydrological soil group. These together cover 27.44 % of the study area. Ref (Table No 7.11)


Hydrological soil group 2 is represented by soil mapping units, 5, 6, 7, 8, 10, 11 and 24. These

soils have some limitations and thus are suitable for limited land irrigation practices. These soils

are suitable for growing double crops or irrigated horticultural practices.. The soil series namely

Baran, Dumkaladak, Patharia, Sarjori, Murabari and Telepara are associated with this

hydrological soil group. These together cover 48.63 % of the study area. Ref (Table No 7.11)


Hydrological soil group 3 is represented by soil mapping unit, 3, 15 and 16. These soils have

severe limitations in terms of erosion, depth and thus are not suitable for land irrigation

practices. These soils are suitable for growing dryland horticultural crops. The soil series namely

Khoripania, Sahargaon, Baramasia are associated with this hydrological soil group. These

together cover 4.65% of the study area. Ref (Table No 7.11)

Hydrological soil group 4 is represented by soil mapping units, 1, 2, 4, 13, 14 and 17. These

soils have very severe limitations in terms of erosion, depth and thus are not suitable for land

irrigation practices. These soils are non aerable lands and thus do not support agricultural

practices however suitable for forest vegetation. The soil series namely, Bagnal, Amra, Dumka,

and Baramasia, Govindpur are associated with this hydrological soil group. These together

cover 3.88% of the study area. Ref (Table No 7.11)

7.7.2 Water Harvesting its storage and management

The Dumka district has a typical physiographical setup as only 12.01% of the total geographical

area is covered by hills and steep slopes where as 19.78 % of area is covered by upper

Pediplain. Valley fills cover about 25.75% of the area. This peculiar situation is very suitable for

implementation of insitu soil moisture and water conservation measures. The small first order

streams emerging from high hill slopes is suitable for construction of gully plugs. Series of gulley

plugs should be taken to check the velocity of running water. The foot hill areas are suitable for

construction of earthen check dams. The alluvial plains are suitable for rain water harvesting

through farm ponds. The farm ponds are not only water harvesting structure but also useful for

protective irrigation under prolonged dry spells during rainy seasons. Contour bunding is

recommended on hill slopes to protect soil from erosion.

The density of irrigation wells in the district is very low. Under the situation currently there is no

need for implementation of artificial recharge projects.

CHAPTER 8 REFERENCES – Soil Series Description and Chemical Analysis Data

BAGNAL SERIES:‐

Bagnal Series is a member of coarse loamy, mixed, hyperthermic, Typic Ustorthents. It is moderately

deep coarse loamy with reddish brown to dark reddish brown, medium acidic developed over

weathered material of Gneissic origin. These are found to occur on hills and ridges. These are severely

eroded excessively drained with moderate permeability. These are unbunded soils under open

moderately dense mixed deciduous forest vegetation.

These soils are medium in acid on surface while becoming strong acidic in sub soil layers although these

are high in Organic carbon and available potassium but low in available phosphorus and zinc. These soils

have poor moisture holding capacity due to high run off. These have high organic carbon due to good

forest cover. These are low in available phosphorus and zinc but moderate to high in potassium.

These are not fit for agriculture due to its topography. It should be protected from grazing and

deforestation by contour trenching, fencing and afforestation. Bagnal soils occur in association with

Sagar Series and Amra Series. Proper soil and water conservation measures are highly essential

protecting by being denudation and maintained its fertility and valuable vegetative cover.

surface soil with high brown to brown, extremely acid to strongly acid. Solum is developed over gneissic

rock these are found to occur on strongly to moderately sloping on Pediment. These are moderately to

strongly eroded, well drained. moderate to rapid permeability. These are unbunded under densely

mixed deciduous forest vegetation.

The series has low organic carbon, small phosphorus, low zinc, while high in available potassium. Due to

restriction in solum depth these soils cannot be brought under cultivation, however it should be

protected from grazing and deforestation

Amra Series (AR1-2)

Amra series is a member of loamy skeletal, shallow, mixed, hyperthermic family of Lithic Ustorthents. It

consists of very shallow to shallow loamy skeletal soils with dark brown to yellowish brown, strongly acidic

AC horizons developed over granite gneiss parent material. These soils are found to occur on strongly to

extremely sloping hill side slopes. These are severely eroded, well to excessively drained with moderately

slow to moderate permeability. These are unbunded soils under open moderately dense mixed deciduous

forest vegetation.

Amra soils have poor moisture holding capacity due to high runoff and skeletal materials. The series has

high organic carbon due to good forest cover, high K2O but low P2O5 availability. These are not fit for

agriculture due to its topography. It should be protected from grazing and deforestation by contour

trenching, fencing and afforestation.

Amra occurs in association with R.O.C., Dumka, Ichak and Baghiari soil series. Proper soil and water

conservation measures are highly essential to protect these soils from being denuded and maintain its

fertility and valuable vegetative cover.

18. Dumka Series (D2): [Photo Plate – R-6-12] [72H/12-1] [Established]

Dumka series is a member of loamy skeletal shallow mixed, hyperthermic family of Typic Ustorthents. It

consists of shallow, loamy skeletal soils with light brown to brown, strongly acidic, gravelly loamy sand to

gravelly sandy loam. AC1 horizon and strongly acidic reddish gray to yellowish brown, gravelly sandy

loam to gravelly sandy clay loam AC2 horizon developed over granite gneiss parent material. These soils

are found to occur on gently to moderately sloping plateau plains having convex slope. These are

severely eroded, well drained with moderately rapid permeability yielding high runoff. These soils are

unbunded, mostly under forest cover and lying waste, but occasionally cultivated for small millets under

rain fed conditions and yields are poor.

Dumka soils are poor in moisture holding capacity due to high percentage of coarse fragments and its

shallow depth, high organic carbon due to good forest cover, medium K2O availability but very low

available P2O5. These soils are not fit for cultivation but can be better used for agro-forestry and pasture

development. These soils cover an extensive area through out the state.

Dumka occurs in association with Amra Laxmipur and Ichak, soil series. Dumka soils require sustainable

soil and water conservation measures like afforestation and contour trenching. Prevention of cattle

grazing will improve grass and vegetative forest covers to prevent the prevailing severe erosion.

Cultivation of these lands should not be encouraged. They are lying mostly as cultivable and non-

cultivatable waste and fallow land having good potential for agro-forestry.

Typifying Pedon: Dumka gravelly loamy sand (Native vegetation and pasture)

Depth (cm)


AC1 0-12 Light brown (7.5 YR 6/3 d) and brown (7.5 YR 5/3 m); gravelly loamy sand; weak, fine, granular to massive; non sticky non plastic, friable and loose; abundant coarse fragments; many very fine to fine pores; abundant very fine roots; clear and smooth boundary; pH-5.40.

AC2 12-23 Light reddish brown (5 YR 6/3 d) and reddish brown (5 YR 5/3 m); gravelly sandy loam; moderate, medium sub-angular blocky to massive; slightly sticky, non plastic and loose; abundant coarse fragments of gravel size; many very fine to fine pores; few fine roots; abrupt and smooth boundary; pH-5.34.

119

Range in Characteristics: Solum depth ranges from 18 to 24 cm. Soil moisture regime is marginally

Ustic. AC horizons are 18 to 25 cms in thickness. These soils have no diagnostic horizons except ochric

epipedon. Horizons are complexes of A and C and are separated by texture, colour and amount of coarse

fragments in the pedon. Surface layers are 10-12 cm thick having the same thickness of underlying sub-

surface. Texture of the surface layer ranges from gravelly loamy sand to gravelly sandy loam with gravelly

sandy loam to gravelly sandy clay loam sub-surface layers Colour ranges from dark yellowish brown to

strong brown on the surface in hues of 7.5 YR to 5 YR with values and chromas of 4-5 and 2-4

respectively and brown to reddish brown in the sub-surface in hues of 5 YR to 7.5 YR with values and

chroma of 4-5 and 3-8 respect layers. Structure of the surface layer is single grained to sub-angular

blocky and massive in the surface and sub-surface layers respectively. Its B.I.R is moderately rapid (8.0-

cm/hr).
