Question

give three points of crop rotation
​

Answer 1

Answer:

Good crop rotation is a systematic succession of the three general classes of farm crops, namely, cultivated crops, grain crops and grass crops. This is practised in such a way to give large yields and provide pasture and forage on the farm at the least expense of labour and soil fertility.

Answer 2

Different crops require different sets of nutrients.It is better to rotate the crops instead of growing the same crop year after year. The same crop will make the soil deficient in the perticular sets of nutrients required by it. usually pulses are alternated with wheat and rice crops. This helps to maintain the nutrients level in the soil.Crop rotation is a succession of crops grown on the same land.
