ABSTRACT
The study of dierent types of soil samples to determine the
type of plants that can be grown in them and also where they
can be found. In order to determine this we have used thebasis of pH of the soil by conducting experiments to nd out
the pH of dierent types soil samples!around 1"# collected by
us from dierent parts of $hennai including botanical gardens%
Tnagar% Tambaram% $entral %along with soils from dierent parts
of our campus.

INTRODUCTION:
3oil properties largely determine the tree species that will growon a site. /mong the many soil properties% soil pH is one of the
most important. Soil pH provides a good indication of thechemical status of the soil and can be used in part to determinepotential plant growth.
SOIL pH:
Soil pH% by denition% is a measure of the activity of hydrogenions in the soil solution.
4eutral soils5 pH !+.)5.)# /cidic soils5pH 67+.) 8asic soils5pH97.)
:ost of the soils generally have a pH scale *5;.
IMPORTANCE OF SOIL pH:
3oil pH in.)# can ma=e some nutrientstoxic and others unavailable to plants. /t low pH levels !6,.)#%aluminum% iron% and manganese are very available for plantupta=e.
/t high pH levels !9.)#% calcium and potassium are overabundant. In these situations% many plants will ta=e up toomuch of these nutrients% while absorbing insu?cient amounts
of the others.

In order to study the soil property of the samples collected byus we conducted an experiment to determine the pH of thesamples .The details of the experiment are as follows.
EXPERIMENT
AIM: To determine the pH of the soil samples.
APPARATUS REQUIRED:3oil 3amples% Indicator li0uid% distilled water% /luminiumsulphate % test tubes% test tube holders.
THEORY: The pH scale measures the acidity or the al=alinity of asubstance. The pH scale
goes from pH1 to pH1,. pH1 is the most acid% pH1, is the mostal=aline and pH is neutral !neither acid nor al=aline#.

!4@T-A The barium sulphate powder is neutral. It is included ineach tube to bind with the particles of soil so that they fall to
the bottom of the tube after it has been sha=en. This allows youto see the colour of the li0uid more easily.#
&. 3ha=e the test tube vigorously for a few seconds. !4@T-APlace your thumb over the rubber bung to stop it falling out.3ha=e until the soil sample completely mixes with the rest ofthe contents of the test tube.#
*. 'abel your test tube and replace it in the test tube rac=.'eave it until the contents have settled.
,. epeat the above steps with the three other soil samples.
). The colours of the li0uid in each of the four test tubes are tobe compared with the standards provided. /nd the records willbe recorded.
+. /lso determine the acidic and al=aline nature of thecorresponding soil samples from their pH values.

CONCLUSION:
$ollecting the soil samples and analysing them has taught usthe importance of various parameters !especially pH# in a soil
for the growth of plants and su?cient supply of nutrients fortheir growth. /lso we have observed the eect of topographyon a soil. (or e.g. the soil sample collected at the roadside isunt for growth of most plants except for wild grass which is0uite expected as there is no need for plants to be grown inthat area.
