• A. True
• B. False

Answer 1

The correct option is A

True

Fertilizer is a substance, natural or synthetic, added to the soil to increase the yield of crops. It is rich in nutrients like nitrogen, phosphorus, potassium and other micronutrients. Manure, on the other hand, is of biological origin and has more amount of organic material i.e. humus. Manures have a low concentration of nutrients. Humus increases the quality of the soil.
