What is crop rotation and how it is useful
The crop rotation method involves growing of set of crops in regular succession over the same piece of land (field) in a specific period of time
The goals of crop rotation are to help manage soil fertility and also to help avoid or reduce problems with soil-borne diseases and some soil-dwelling insects, such as corn rootworms. It is one of the oldest agricultural methods to increase yield per acre.
*Crop rotation maintains and improves soil fertility.
*Crops grown in one period of time utilize one set of nutrients. Different crops grown in the following time period utilize the other set of nutrients so that this time will be enough for the first set of nutrients to replenish themselves.
*Controls soil erosion.
*Prevents soil depletion
*Prevents growth of pests, weeds & soil diseases.
*Controls insect/mite pests. Crop rotation as a means to control insect pests is most effective when the pests are present before the crop is planted have no wide range of host crops; attack only annual/biennial crops; and do not have the ability to fly from one field to another.
