Question

How is manure obtained?

Answer 1

Hint: Manure is an organic matter. It is mostly produced from the faeces of animals. It is used as a fertilizer in agriculture. The fertility of the soil is maintained by manure as it provides lots of nutrients and organic matter. Manure is rich in nitrogen which is beneficial as bacteria traps the nitrogen in the soil.

Complete answer:
- When the dead plants and animals decay it leads to the formation of manure, which is used for the soil to increase production. It is a natural fertilizer that is non-toxic and cost-effective.
- The excreta of animals and humans is also used as manure. The manure of livestock is rich in potassium, nitrogen, and phosphorus.
- Manure is obtained when the animal and plant waste are dumped by farmers in an open pit and leave it for days. The waste starts to decompose by the action of certain microorganisms, this process is called decomposition. Finally, the decomposed organic matter becomes Manure.
- Manure can be obtained from various sources like cattle dung from the biogas plant, agriculture wastes, from human habitation, excreta of sheep and goats, etc.

There are various advantages of manure:
- It is cost-effective.
- The fertility of the soil is improved.
- It is a good source of different types of nutrients.
- The water holding capacity of soil increases.

Note: There are different types of manures available for farmers:
- Green manure: The amount of organic matter gets increased by using green manure.
- Compost manure: The structure of soil and water holding capacity improves
- Farmyard manure: It also improves the soil structure and its minerals supply due to the improved microbial activity.
