Soil pH:

Soil samples were used to measure the pH of the soil. Each replicate was subjected to pH analysis to determine the average acidic or alkaline nature of the soil. The pH meter was used which was standardized with buffers provided by the manufacturers that were of 4.01, 7.00, 10.00 standards. 5g soil was added with 20ml of distilled water and shook well for about an hour. Then the soil solution was left to settle down, pH meter was placed in the supernatant to measure the value of pH. Readings of the pH were taken three times for absolute certainty.
