This soil survey is a publication of the National Cooperative Soil Survey, a joint effortof the United States Department of Agriculture and other Federal agencies, Stateagencies including the Agricultural Experiment Stations, and local agencies. TheNatural Resources Conservation Service (formerly the Soil Conservation Service) hasleadership for the Federal part of the National Cooperative Soil Survey.

Major fieldwork for this soil survey was completed in 2000. Soil names anddescriptions were approved in 2002. Unless otherwise indicated, statements in thispublication refer to conditions in the survey area in 2002. This survey was madecooperatively by the Natural Resources Conservation Service and the MissouriDepartment of Natural Resources; Missouri Agricultural Experiment Station; UnitedStates Department of Agriculture, Forest Service; Missouri Department ofConservation; Howell County Soil and Water Conservation District; and Howell CountyCommission. The survey is part of the technical assistance furnished to the HowellCounty Soil and Water Conservation District.

Soil maps in this survey may be copied without permission. Enlargement of thesemaps, however, could cause misunderstanding of the detail of mapping. If enlarged,maps do not show the small areas of contrasting soils that could have been shown at alarger scale.

This soil survey contains information that affects land use planning in this surveyarea. It contains predictions of soil behavior for selected land uses. The survey alsohighlights soil limitations, improvements needed to overcome the limitations, and theimpact of selected land uses on the environment.

This soil survey is designed for many different users. Farmers, ranchers, foresters,and agronomists can use it to evaluate the potential of the soil and the managementneeded for maximum food and fiber production. Planners, community officials,engineers, developers, builders, and home buyers can use the survey to plan land use,select sites for construction, and identify special practices needed to ensure properperformance. Conservationists, teachers, students, and specialists in recreation, wildlifemanagement, waste disposal, and pollution control can use the survey to help themunderstand, protect, and enhance the environment.

Various land use regulations of Federal, State, and local governments may imposespecial restrictions on land use or land treatment. The information in this report isintended to identify soil properties that are used in making various land use or landtreatment decisions. Statements made in this report are intended to help the land usersidentify and reduce the effects of soil limitations on various land uses. The landowner oruser is responsible for identifying and complying with existing laws and regulations.

Great differences in soil properties can occur within short distances. Some soils areseasonally wet or subject to flooding. Some are shallow to bedrock. Some are toounstable to be used as a foundation for buildings or roads. Clayey or wet soils arepoorly suited to use as septic tank absorption fields. A high water table makes a soilpoorly suited to basements or underground installations.

These and many other soil properties that affect land use are described in this soilsurvey. Broad areas of soils are shown on the general soil map. The location of eachsoil is shown on the detailed soil maps. Each soil in the survey area is described.Information on specific uses is given for each soil. Help in using this publication andadditional information are available at the local office of the Natural ResourcesConservation Service or the Cooperative Extension Service.

HOWELL COUNTY is in the south-central part ofMissouri (fig. 1). It has a total area of 593,754 acres, orabout 928 square miles. It is bordered on the north byTexas County, Missouri; on the west by Douglas andOzark Counties, Missouri; on the east by Shannonand Oregon Counties, Missouri; and on the south byFulton County, Arkansas. West Plains, the county seat,is in the central part of the county. According to the2000 census, the population of Howell County was37,238 and the population of West Plains was 10,866(Johnson, 1989). Other communities includeBrandsville, Caulfield, Mountain View, Pomona, andWillow Springs.

A majority of the county supports timber, bothmature and regenerating stands. The remaining areas,including some gently sloping and moderately slopingareas of uplands and a major part of the bottomlands,are used for pasture and hay. Beef and dairy cattle arethe dominant livestock species in the county. Cool-season grasses and shallow-rooted and deep-rootedlegumes, including fescue, red clover, and alfalfa, arethe main forage species grown for pasture and hay.

The county is dominantly rural. The local economyis based on retail business, livestock farming, servicefacilities, and tourism. Several small towns havebusiness districts that are supported by thesurrounding rural areas.

A total of 49,043 acres of the county is public land.

Soil Survey of

Howell County, Missouri

This acreage is used extensively for hunting, camping,and hiking.

This soil survey updates the survey of HowellCounty, Missouri, published in 1902 (USDA, 1902). Itprovides additional information and has larger maps,which show the soils in greater detail.

12 Soil Survey of

General Nature of the CountyThis section gives general information about the

county. It describes climate, history and development,and relief and drainage.

Climate

By the Natural Resources Conservation Service, NationalWater and Climate Center, Portland, Oregon.

The climate tables were created from data recordedat West Plains, Missouri. Thunderstorm days, relativehumidity, percent sunshine, and wind information wereestimated from data recorded at the First Order stationat Springfield, Missouri.

Table 1 gives data on temperature and precipitationfor the survey area as recorded at West Plains in theperiod 1961 to 1990. Table 2 shows probable dates ofthe first freeze in fall and the last freeze in spring.Table 3 provides data on the length of the growingseason.

In winter, the average temperature is 38.2degrees F and the average daily minimumtemperature is 23.3 degrees. The lowesttemperature on record, which occurred atWest Plains on February 2, 1951, was 21 degrees.In summer, the average temperature is 75.4 degreesand the average daily maximum temperature is87.5 degrees. The highest temperature, whichoccurred at West Plains on July 12, 1980, was107 degrees.

Growing degree days are shown in table 1. Theyare equivalent to heat units. During the month,growing degree days accumulate by the amount thatthe average temperature each day exceeds a basetemperature (50 degrees F). The normal monthlyaccumulation is used to schedule single or successiveplantings of a crop between the last freeze in springand the first freeze in fall.

The average annual total precipitation is about45.05 inches. Of this, about 27.0 inches, or 60 percent,usually falls in April through October. The growingseason for most crops falls within this period. Theheaviest 1-day rainfall during the period of record was5.35 inches at West Plains on April 3, 1957.Thunderstorms occur on about 52 days each year,and most occur in May through August.

The average seasonal snowfall is 13 inches. Thegreatest snow depth at any one time during theperiod of record was 16 inches recorded onFebruary 8, 1980. On an average, 13 days per yearhave at least 1 inch of snow on the ground. Theheaviest 1-day snowfall on record was 15 inchesrecorded on March 9, 1984.

The average relative humidity in midafternoon isabout 60 percent. Humidity is higher at night, and theaverage at dawn is about 83 percent. The sun shines66 percent of the time possible in summer and 50percent in winter. The prevailing wind is from the southfor most of the year, but it is from the northwest inFebruary and March. Average windspeed is highest, 11to 12 miles per hour, in November through April.

History and Development

Prepared by Robert D. Rouse, soil scientist, MissouriDepartment of Natural Resources.

Howell County was part of Ripley County when theearliest settlers began to move into the area. In thesummer of 1829, a hunter became the first settler inHowell County. He settled by a spring that is nowwithin the city limits of West Plains. Later he sold hisproperty to a member of the Howell family who movedinto the area from Smith County, Tennessee, in the fallof 1839. The county bears the name of thesepermanent settlers.

In 1848 the government sent surveyors into thearea to lay section lines. After reading the reports fromthe surveyors, many people began to move into thearea. Most of the early settlers had strong religiousbeliefs, and they built buildings that could be used aschurches, schools, and government offices and forcommunity get-togethers.

In December 1848, Josephus Howell wasappointed postmaster of the first post officeestablished in the area, which by then was known asHowell County. The area supported very little timber.It was mostly covered with bluestem prairie grass, soCircuit Judge John Woodside named the post officeWest Plains in honor of the plains west ofThomasville (Schroeder, 1982).

The population of the area continued to increase,so Howell County was organized on March 2, 1857.The first Circuit Court was held the next month at oneof the local schools. By 1860 the county had 3,169residents, 150 of which lived in the town of WestPlains.

The Civil War of 1861 had a devastating effect onthe population of Howell County. Once GovernorJackson issued a proclamation calling Missouri toarms, State Representative John Woodside beganrecruiting men for the Confederacy. The countyorganized three companies of Confederate soldiers.By 1863 all but 200 residents had left the county. In1864 West Plains was burned to the ground byrenegades. Rebuilding did not begin until 1866.

The census of 1870 showed 4,218 residents inHowell County. That same year B.F. Olden and Sam

Risley started The South Missouri Journal, which wasthe first permanent newspaper in the county. Later thename was changed to The West Plains Journal. Therailroad came to the county in 1883, with a depot inWest Plains. The availability of goods brought by railwas partially responsible for the growth of the county.By 1890 the county had a population of 18,618. Therailroad was used to transport products from thecounty to other parts of the country. Many sawmillswere constructed in the northwest part of the county toproduce lumber, and many boxcar loads of fruit wereshipped.

Today timber still remains a major industry in HowellCounty. The hopes of the county becoming a majorfruit-producing region, however, have long since fadedas have the plans to mine zinc, lead, silver, and ironore. Beef cattle production and related enterprises arethe dominant agricultural enterprises in the county.

Relief and Drainage

Howell County has a wide variety of landscapes.The county is on the Salem Plateau, which is part ofthe Springfield-Salem Plateaus section of the OzarkPlateaus province. Elevation ranges from 1,560 feetabout 4 miles north of Willow Springs, in thenorthwestern part of the county, to 600 feet whereMyatt Creek flows into Fulton County, Arkansas, in thesoutheast corner of the county.

A major divide, which is north of State Highway 60,extends across the northern portion of the county. Thisdivide branches to the southeast through Burnhamand Pomona and west of West Plains. It has manybroad lateral ridges that extend from the main divideand run east, west, and south across the county. Thehighest portion of this divide consists of narrowundulating ridges with many high convex hills. Theseareas are underlain by Pennsylvanian residual clay.King Mountain, east of Willow Springs, is an example.As the lateral ridges extend farther from the maindivide, they are lower in elevation and become broaderand flatter. These broad gently sloping and slopingridges are underlain by Jefferson City residual clay.

Howell County has been deeply dissected byseveral major rivers and their tributaries. The northernedge of the county drains into tributaries of the JacksFork River. The tributaries are flanked by very steephillsides with narrow gravelly flood plains. The westernpart of the county drains into tributaries of the WhiteRiver. These tributaries are flanked by sloping hillsidesin the upper part of the watershed to very steephillsides farther downstream. The eastern part of thecounty drains into the Eleven Point River and itstributaries. Sloping hillsides, gently sloping basins, and

broad stream terraces flank the upper part of thewatershed. The lower part of the watershed is flankedby very steep hillsides. The Spring River and itstributaries drain the southern part of the county.Sloping hillsides, gently sloping basins, and broadstream terraces flank the upper part of the watershed.Many of these basins and stream terraces are poorlydrained. The lower part of the watershed is flanked byvery steep hillsides. All of the watersheds in the countyeventually flow south into the White, Eleven Point, andCurrent Rivers in Arkansas.

How This Survey Was MadeThis survey was made to provide information about

the soils and miscellaneous areas in the survey area.The information includes a description of the soils andmiscellaneous areas and their location and adiscussion of their suitability, limitations, andmanagement for specified uses. Soil scientistsobserved the steepness, length, and shape of theslopes; the general pattern of drainage; the kinds ofcrops and native plants; and the kinds of bedrock.They dug many holes to study the soil profile, which isthe sequence of natural layers, or horizons, in a soil.The profile extends from the surface down into theunconsolidated material in which the soil formed. Theunconsolidated material is devoid of roots and otherliving organisms and has not been changed by otherbiological activity.

The soils and miscellaneous areas in the surveyarea are in an orderly pattern that is related to thegeology, landforms, relief, climate, and naturalvegetation of the area. Each kind of soil andmiscellaneous area is associated with a particular kindof landform or with a segment of the landform. Byobserving the soils and miscellaneous areas in thesurvey area and relating their position to specificsegments of the landform, a soil scientist develops aconcept or model of how they were formed. Thus,during mapping, this model enables the soil scientistto predict with a considerable degree of accuracy thekind of soil or miscellaneous area at a specific locationon the landscape.

Commonly, individual soils on the landscape mergeinto one another as their characteristics graduallychange. To construct an accurate soil map, however,soil scientists must determine the boundaries betweenthe soils. They can observe only a limited number ofsoil profiles. Nevertheless, these observations,supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient toverify predictions of the kinds of soil in an area and todetermine the boundaries.

Soil scientists recorded the characteristics of thesoil profiles that they studied. They noted soil color,texture, size and shape of soil aggregates, kind andamount of rock fragments, distribution of plant roots,reaction, and other features that enable them toidentify soils. After describing the soils in the surveyarea and determining their properties, the soilscientists assigned the soils to taxonomic classes(units). Taxonomic classes are concepts. Eachtaxonomic class has a set of soil characteristics withprecisely defined limits. The classes are used as abasis for comparison to classify soils systematically.Soil taxonomy, the system of taxonomicclassification used in the United States, is basedmainly on the kind and character of soil propertiesand the arrangement of horizons within the profile.After the soil scientists classified and named thesoils in the survey area, they compared the individualsoils with similar soils in the same taxonomic class inother areas so that they could confirm data andassemble additional data based on experience andresearch.

While a soil survey is in progress, samples of someof the soils in the area generally are collected forlaboratory analyses and for engineering tests. Soilscientists interpret the data from these analyses andtests as well as the field-observed characteristics andthe soil properties to determine the expected behaviorof the soils under different uses. Interpretations for allof the soils are field tested through observation of thesoils in different uses and under different levels ofmanagement. Some interpretations are modified to fit

local conditions, and some new interpretations aredeveloped to meet local needs. Data are assembledfrom other sources, such as research information,production records, and field experience of specialists.For example, data on crop yields under defined levelsof management are assembled from farm records andfrom field or plot experiments on the same kinds ofsoil.

Predictions about soil behavior are based not onlyon soil properties but also on such variables asclimate and biological activity. Soil conditions arepredictable over long periods of time, but they are notpredictable from year to year. For example, soilscientists can predict with a fairly high degree ofaccuracy that a given soil will have a high water tablewithin certain depths in most years, but they cannotpredict that a high water table will always be at aspecific level in the soil on a specific date.

After soil scientists located and identified thesignificant natural bodies of soil in the survey area,they drew the boundaries of these bodies on aerialphotographs and identified each as a specific mapunit. Aerial photographs show trees, buildings, fields,roads, and rivers, all of which help in locatingboundaries accurately.

The descriptions, names, and delineations of thesoils in this survey area do not fully agree with thoseof the soils in adjacent survey areas. Differences arethe result of a better knowledge of soils, modificationsin series concepts, or variations in the intensity ofmapping or in the extent of the soils in the surveyarea.

The general soil map in this publication showsbroad areas that have a distinctive pattern of soils,relief, and drainage. Each map unit on the general soilmap is a unique natural landscape. Typically, itconsists of one or more major soils or miscellaneousareas and some minor soils or miscellaneous areas. Itis named for the major soils or miscellaneous areas.The components of one map unit can occur in anotherbut in a different pattern.

The general soil map can be used to compare thesuitability of large areas for general land uses. Areasof suitable soils can be identified on the map. Likewise,areas where the soils are not suitable can beidentified.

Because of its small scale, the map is not suitablefor planning the management of a farm or field or for

selecting a site for a road or building or other structure.The soils in any one map unit differ from place to placein slope, depth, drainage, and other characteristicsthat affect management.

The map units delineated on the detailed soil mapsin this survey represent the soils or miscellaneousareas in the survey area. The map unit descriptions inthis section, along with the maps, can be used todetermine the suitability and potential of a unit forspecific uses. They also can be used to plan themanagement needed for those uses.

A map unit delineation on a soil map represents anarea dominated by one or more major kinds of soil ormiscellaneous areas. A map unit is identified andnamed according to the taxonomic classification of thedominant soils. Within a taxonomic class there areprecisely defined limits for the properties of the soils.On the landscape, however, the soils are naturalphenomena, and they have the characteristicvariability of all natural phenomena. Thus, the range ofsome observed properties may extend beyond thelimits defined for a taxonomic class. Areas of soils of asingle taxonomic class rarely, if ever, can be mappedwithout including areas of other taxonomic classes.Consequently, every map unit is made up of the soilsor miscellaneous areas for which it is named andsome minor components that belong to taxonomicclasses other than those of the major soils.

Most minor soils have properties similar to those ofthe dominant soil or soils in the map unit, and thusthey do not affect use and management. These arecalled noncontrasting, or similar, components. Theymay or may not be mentioned in a particular map unitdescription. Other minor components, however, haveproperties and behavioral characteristics divergentenough to affect use or to require differentmanagement. These are called contrasting, ordissimilar, components. They generally are in smallareas and could not be mapped separately because ofthe scale used. Some small areas of stronglycontrasting soils or miscellaneous areas are identifiedby a special symbol on the maps. The contrastingcomponents are mentioned in the map unitdescriptions. A few areas of minor components maynot have been observed, and consequently they arenot mentioned in the descriptions, especially wherethe pattern was so complex that it was impractical tomake enough observations to identify all the soils andmiscellaneous areas on the landscape.

The presence of minor components in a map unit inno way diminishes the usefulness or accuracy of thedata. The objective of mapping is not to delineate puretaxonomic classes but rather to separate thelandscape into landforms or landform segments thathave similar use and management requirements. Thedelineation of such segments on the map providessufficient information for the development of resourceplans. If intensive use of small areas is planned,however, onsite investigation is needed to define andlocate the soils and miscellaneous areas.

An identifying symbol precedes the map unit namein the map unit descriptions. Each description includesgeneral facts about the unit and gives the principalhazards and limitations to be considered in planningfor specific uses.

Soils that have profiles that are almost alike makeup a soil series. Except for differences in texture of thesurface layer, all the soils of a series have majorhorizons that are similar in composition, thickness,and arrangement.

Soils of one series can differ in texture of thesurface layer, slope, stoniness, salinity, degree oferosion, and other characteristics that affect their use.On the basis of such differences, a soil series isdivided into soil phases. Most of the areas shown onthe detailed soil maps are phases of soil series. Thename of a soil phase commonly indicates a featurethat affects use or management. For example, Tonti siltloam, 3 to 8 percent slopes, is a phase of the Tontiseries.

Some map units are made up of two or more majorsoils or miscellaneous areas. These map units arecomplexes.

A complex consists of two or more soils ormiscellaneous areas in such an intricate pattern or insuch small areas that they cannot be shownseparately on the maps. The pattern and proportion ofthe soils or miscellaneous areas are somewhat similarin all areas. Branson-Splitlimb complex, 1 to 3 percentslopes, is an example.

This survey includes miscellaneous areas. Suchareas have little or no soil material and support little orno vegetation. Rock outcrop is an example.
