Question
Given below are two statements: Statement I:
Salinity present in the irrigation water is given in terms of ESR value. Statement II: The extent of soil salinization and/or sodication depends on the type and amount of salt, their relative abundance in soil and effect on soil pH. In the light of the above Statements, choose the correct answer from the options given below:Solution
Statement I mentions that salinity present in irrigation water is given in terms of ESR (Exchangeable Sodium Ratio) value. This is not true statement, as ESR is a commonly used parameter to assess the salinity hazard of soil. Statement II states that the extent of soil salinization and/or sodication depends on the type and amount of salt, their relative abundance in soil, and their effect on soil pH. It also depends on various other factors, including the specific types of salts present, their concentration, the soil texture, and other environmental conditions.Â
