Explain in brief about the Crop Rotation

1.  Deep rooted legumes may be grown periodically over all fields.

2.  There is more continuous vegetative cover and probably less erosion.

3.  Tilth of the soil may become superior.

4.  Crops varying in feeding range of roots and nutrient requirements may be grown. 

5.  Weed and insect control are favoured, although chemicals are becoming increasingly effective.

6.  Disease control is favoured; changing the crop residues fosters competition among soil organisms and may reduce the pathogens.
