Benefits of crop rotation

A crop rotation is a sequence of crops grown in recurring succession on the same area of land. It provides for growing of different crops rather than continuous culture to one crop and for the growing of these different crops in systematic order rather than in haphazard fashion. The mere fact that crops are grown in systematic rotation does not necessarily ensure either good farming or good soil management, for rotations may be bad as well as good. But the rotation of crops does provide the opportunity for effective land-management and soil-conservation practices. In fact, the major benefits to be derived from a well-planned crop rotation accrue to the land.

Benefits of crop rotation. The benefits to be derived from desirable crop rotations may be classed as follows:
1.      Because differences in feeding habits are advantageous and because of other considerations, most crops yield better following other crops than they do following themselves or crops of similar feeding habits.
2.      Crop rotations provide an opportunity to restore organic matter to the soil.
3.      In a rotation, plant nutrients may be returned to the soil as manure and commercial fertilizer applied to the crops most likely to respond with paying returns.
4.      Crop rotations can be so planned as to curtail greatly losses caused by erosion.
5.      A series of feed and cash crops diversifies the sources of farm income.
6.      The growing of crops with different seasonal requirements distributes labor and makes possible more effective farm management.
7.      Crop rotations make possible the reduction of losses caused by certain, weeds, insets, and plant diseases.
