• A. Increase in microbial content of the soil
• B. Increase in biodegradable waste
• C. Increase in agricultural waste
• D. Both A and B

Answer 1

The correct option is C Increase in agricultural waste

The harmful change in the colour, texture, and quality of soil due to addition and removal of any material is called soil pollution. Soil pollution reduces the productivity of the soil. There are several pollutants that cause soil pollution. For example, agricultural wastes, radioactive wastes and discarded materials of hospitals etc. The agricultural waste includes pesticides, insecticides, fertilizers, weedicides etc. These are the chemicals that are involved in changing the pH of the soil. For example, repeated use of fertilizers makes the soil acidic which in turn decreases the productivity of the soil. So, the correct option is C.
