The document summarizes the current status of a student project testing soil and studying groundwater pollutants. It describes how the students determined the pH, organic matter, available phosphorus, and electrical conductivity of samples from two locations. The results found the pH of both samples to be alkaline, low levels of organic carbon and salt, and medium available phosphorus. The next objectives of the project are outlined, which include determining additional soil properties and studying water pollutants.

3. INTRODUCTION
 Soil testing is a special chemical analysis that provides a guideline
for lime and fertilizer needs of soils when considered in
conjunction with post-fertilizer management and cropping history.
 A soil test is the analysis of a soil sample to
determine nutrient and contaminated content, composition, and
other characteristics such as the acidity or pH level. A soil test can
determine fertility, or the expected growth potential of the soil
which indicates nutrient deficiencies, potential toxicities from
excessive fertility and inhibitions from the presence of non-
essential trace minerals.

4. CURRENT STATUS:
DETERMINATION OF SOIL pH:
INTERPRETATION
R
RESULT:- Sample 1. (from sliet) pH value – 8.39
sample 2.(from sangrur field) pH – 8.17
pH Category Recomendation
Below 6.5 Acidic Requires liming for
reclamation
6.5-8.7 Normal Optimum for most crops
8.2-9.3 Alkaline Requires application of
organic manures
Above 9.3 Alkali (sodic) Requires gypsum

5. DETERMINATION OF ELECTRICAL
CONDUCTIVITY OF SOIL
INTERPRETATION :
RESULT : Sample 1.(sliet)-E.C = .65 dS/m, and %of salt concentration = 0.05
sample2. (sangrur field) E.C= .65 dS/m & % of soil concentration=0.05
EC 1:2 Soil concentration (%) Category
Below 0.8 Below .05 Normal
0.8-1.6 0.05-0.15 Critical for salt sensitive
crops
1.6-2.5 0.15-0.20 Critical for salt tolerant
crops
Above 2.5 0.20-0.25 Injurious to all crops

6. Determination of carbon matters in
soil
INTERPRETATION:
RESULT: Sample 1(sliet)- carbon matter %=0.90
Sample 2 (sangrur field)-carbon matter %=0.47
Organic carbon (%) Soil rating
Below 0.40 low
0.40-0.75 Medium
Above 0.75 High

7. DETERMINATION OF PHOSPHOROUS IN
SOIL
INTERPRETATION:
RESULT-Sample 1.(Sliet) :- available P=8.0 kg/acre
sample 2.(sangrur field) available P= 8.2 kg/acre
Available phosphorous (kg/acre) Catogory
Below 5 low
5-9 Medium
9-20 High
Above 20 Very high
