1.	Name the tests for finding out the characteristic of soil. Describe any one method of it.
Answer» There are two tests for finding out the characteristics of soil: (1) pH (2) electrical conductivity tests. 1. pH tests: The Danish scientist Sorensen put forth the concept of pH, based on the concentration of hydrogen ions. To determine the pH of soil, a mixture of water and soil in the proportion of 1 : 2 is taken and tested using several indicators. Accordingly, soil may be found to be one of the following types. Acidic soil – pH less than 6.5 Neutral soil – pH 6.5 – 7.5 Alkaline soil – pH higher than 7.5 2. By Electrical conductivity tests we come to know how many nutrients are present in the soil.
