The crops used are usually of three types – row crops like vegetables, close-growing cereals, and rest crops like legumes or clover. Principle of Crop Rotation Crop Rotation It is defined as the growing of crops in an orderly and well planned way. With monocultures like these, increasing levels of chemical fertilizers and pesticides become necessary to keep yields high while keeping bugs and disease at bay. There is no limit to the total number of crops that can be rotated, some very complex systems of succession can be used. Rotation are used because crops have different requirements for moisture, organic matter, fertility elements, yields generally differ when crops are grown in sequence rather than when one is grown continuously. In other words, it is a system that involves the growing of different crops on the same piece of land year after year, with each crop following the other in a definite sequence. Cover crops can be broadly defined as any non-cash crop grown in addition to the primary cash crop. The rotation of crops in a specified order in a field is one of the oldest and most effective agricultural control measures to regulate weed presence, as well as enriching the soil naturally with nutrients after it is depleted by producing crops, thanks to the nitrogen-fixing properties of leguminous crops included in the rotation.

For example, legumes restore nitrogen to the soil, due to the nitrogen-fixing bacteria in their root nodules. The first number in a rotation ratio refers to cultivated row crops, the second to close-growing grains, and the third to sod-forming, or rest, crops. Integrated Crop Management requires a recognition of the fact that a diverse crop rotation is the most effective indirect means of maintaining soil fertility and controlling pests. They are selected for their part in balancing the composition of the soil and also for profitability. Crop Rotation - Why is it important? Crop rotation is a method of cropping system. However, the main difference between these two types of farming is that organic farmers use a plow or soil tillage, while farmers who practice conservation agriculture use natural principles and do not till the soil. Alternating the crops will destroy the pests by removing their habitat and disrupting their life cycles. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pest and weeds.
