For example,after growing wheat for a season, farmers prefer to grow crop of legume family such as peas,gram and groundnut. The crop rotation is a thousand years old technique that has been proven to help the environment, improve the soil and so many other things. The diversification of cropping sequences takes away the host organism and causes a disruption in the annual life cycle of insects, diseases, and weeds. First, the land itself can become “tired” and less fertile. Tillage can loosen the soil and make it more susceptible to erosion by wind and water. In addition, crop rotation is helpful in long-term soil and farm management. As a result, crop rotation makes a perfect contribution to land use. Crop rotation systems are one cropping system alternative. Improving the soil organic matter and nutrient pools is also a benefit of crop rotation that results in increasing water-holding capacity of the soil. The results of the reports sustain that several factors affect the rate of decomposition of organic amendments. This system is the practice of growing several dissimilar or different crop types (or no crop at all) in the same area and in sequential seasons. Beneficial effects include lower incidence of weeds, insects, and plant diseases, as well as improvements of soil physical, chemical, and biological properties. This affects brassicas or cabbages, cauliflowers and Brussels sprouts. Higher crop yields. The crop rotation definition can be put like changing different kinds of crops year by year in the same field. Crop rotation is also an effective technique to dramatically increase yields and prevent crop loss due to pests or disease. By choosing the crop rotation systems can include impact on soil quality and fertility, environmental quality, and farm profitability. The practice also works to interrupt pest and disease cycles, improve soil health by increasing biomass from different crops’ root structures, and increase biodiversity on the farm. Annual crop rotations affect the root structure over a period. Crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons. Photo Credit: Wikipedia. The adult version of this pesky bug lays eggs on the underside of the spinach leaves. This is because if the same type of crop is planted in the same area, the plant will continue to drain same nutrients from the soil.. Second, certain pests can reach levels that are hard to control. It prevents building up of diseases and pests of particular crop. This can cut agriculture’s dependence on external inputs through internal nutrient recycling. Doing rotation, a crop that draws one kind of nutrient from the soil is followed during the consequent season by a crop that returns the nutrient to the soil or draws a distinct ratio of nutrients. A cycle may include a different number of years, from 3 up to 7+ planting various crops in turns and/or leaving the land fallow to recover. (2) Alternating shallow-rooted and deep-rooted plants in a given area … Along with the other benefits of crop rotation, it may impact the rate of nitrogen mineralization. Photo Credit: Wikipedia. Other, instead of this, rather rotate six or more crops in a field over multiple years. It has several benefits for soil and crop systems. It also has its risks such as less profitability because of decreased acreage of a highly valuable crop. The organic matter feeds the growth of microbes, which increases the release of N as they die and decompose. In addition, the type of vegetable grown in a particular area in a garden has a direct effect on the fertility of the soil in that area. Since the early 1900s, farmers have used cover crops to restore fertility to worn-out land.

Some modern farmers will occasionally allow fields to lie fallow to rest. crop rotation helps in the of soil with soil fertility. A common use of nitrogen it is been showing up over the past 50 years. Caterpillars cause crop damage. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pest and weeds. The implementation of  crop rotation cut the nitrogen fertilizer use and drastically reduce greenhouse gas emissions. Name the nitrogen-fixing bacteria present in root nodules of leguminous plants. Finally, land is more susceptible to the forces of erosion if the same type of crop remains season after season. Rotating your crops means creating an order in the planting of your vegetables so that higher feeders are followed by givers and givers are followed by low feeding vegetable plants. Crop rotation helps return nutrients to the soil without synthetic inputs. Take club root, for instance. For example, a simple rotation between heavy nitrogen using plant (e.g., corn) and a nitrogen depositing plant (e.g., soybeans) can help maintain a healthy balance of nutrients in the soil. Crop rotation helps improve soil biodiversity by changing crop residue and rooting pattens. It helps in reducing soil erosion and increases soil fertility and crop yield.
