Question

Define manure. What are different manures and how do they affect the soil ?

Answer 1

Manures are natural fertilisers. They are the source of organic matter that supply nutrients in small quantities.
There are three types of manure:
1. Farmyard manure (FYM).
2. Compost.
3. Green manure.
Manure enriches the soil with nutrients and adds organic matter (humus) to the soil. Humus improves the soil texture for better water retention and soil aeration.
