In agriculture, crop rotation refers to growing of crops that are different from each other in successions on farm field in a specific period of time. In other words, it is growing of dissimilar crop or no crop during sequential seasons on the same of piece of land. The objective of crop rotation is to get maximum profit from investing minimum or making least investment without harming the fertility of soil.
Historian dates back crop rotation to 6000 B.C. when it was practiced by the farmers of Middle East. Interestingly, it is also believed that those farmers did not know the science behind this practice still the follow it. The logic is simple. It is practiced because if one cultivates same kind of crop over several years, the soil becomes weak and infertile. That same crop requires same kind of nutrients each year. And if crop rotation is not practiced, that kind of nutrients becomes exhausted. These nutrients have an additional duty of keeping the soil stable in terms of keeping the soil texture. In case of same crop growing again and again without crop rotation, the soil becomes susceptible to soil erosion due to weaker bonding between soil particles.
One cycle of crop rotation may acquire 1 or more farming years to complete. For irrigated areas, the farming year is of 12 months. However in rain fed or Barani areas, farming year is restricted to that period of time during which there is adequate availability of soil water.
Crop rotation is carried our extensively and is a common practice. Farm experts are of the view to rotate crops is such a manner that one cereal crop is succeeded by the legumes crop so that crop fertility remain stable.
Benefits of Crop Rotation
- Effective tool to control pest.
- Adequate management of nitrogen in soil or create nitrogen balance in soil.
- Keep soil safe from wind and water erosion.
- Keep greenhouse gas emissions at sustainable levels.
- Increased soil productivity.
- Minimize the use of pesticides thus reducing water and soil pollution.
- Keeps the soil structure good.
- Carbon storing ability increases.
