Question

What are the advantages of using manures in the crop fields?

Answer 1

Hint:- Manure is the organic matter which is made inside the open pits from the animal and plant remains through the action of microorganisms on it.

Complete step-by-step solution:-
Manure is highly rich in humus and organic matter. It can be grouped into three types: farmyard
manure, green manure, and compost manure.
The advantages of using manure in the crop fields are as follows:
The first and foremost advantage of manure in the crop field is that it can be used in the form of
organic fertilizers as it is enriched with nutrients (N, P, etc.) that are essential for plants.
Adding manure to the crop fields makes the soil rich in organic matter and essential nutrients
thereby improving plant growth and development.
Manure is known for holding water content in the soil thereby improving the texture of the soil.
It also helps in the reduction of leaching as well as soil erosion.
Manure does not cost anything to the farmer as it is produced by the decomposition of animal and
plant wastes through the action of microbes in open pits.
It is also known to provide food to the microbes present in the soil thereby improving the condition
of the soil.
As manure is produced from animal and plant remains, hence, it reduces the risk of environmental
pollution.

Note:- Farmers use manure in their crop fields to enhance plant productivity as manure provides certain essential nutrients such as nitrogen, phosphorus to the plant which promotes its growth and development. It is biodegradable, thereby decreasing the reliance on chemical fertilizers which are non-biodegradable.
