But it becomes a fixed rotation when not only the order of the crops is named, but the length of time of each crop is also specified.. 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. Crop rotation in organic agriculture is a system of designing how to cycle a parcel of land through various crops, reducing the reliance on chemical fertilizers, pesticides, and herbicides. In recent decades, they have been subject to intense changes stimulated by biological and technical progress, availability of labor resources, and organizational or economic conditions. In this article, we are are going to see what is crop rotation and what are the advantages of crop rotation in agricultural farming. Just as there is no limit to the number of crops that can be rotated, there is no fixed period for alternating crops. The movement of animals across the field also helps to distribute the nutrients more evenly. • The term cropping system or crop rotation refers to the crops and crop sequences and the management techniques used on a particular field over a period of years.

Agricultural technology - Agricultural technology - Factors in cropping: The kind and sequence of crops grown over a period of time on a given area of soil can be described as the cropping system. Synergism or crop rotation often occurs between certain crops if interchanged. Legumes restore nutrients to the soil by “fixing” in nitrogen. Changing to crop rotation from monoculture can result in improved crop yields by a factor of 20% or more. There is no limit to the total number of crops that can be rotated, some very complex systems of succession can be used. Advice for growers on building the best crop rotation plan to keep disease, pest and weed pressure down, while maximising return on cereals, oilseed rape, beans, sugar beet and potatoes. This depends on the needs of the soil and the farmer. CROP ROTATION IN AGRICULTURE Definition: Crop rotation is defined as the planting of different types of crops on the same piece of land in a definite sequence.

Nonhost crops are crops that cannot support a specific pest or pests of dry beans. Enlarge Image. When the corn harvest is finished, he might plant beans, since corn consumes a lot of nitrogen and beans return nitrogen to the soil. In general, avoid solanaceous crops as rotation choices. This can also help to prevent soil erosion, and reduce the buildup of pathogens and pests that rely on a single plant species. Crop rotation is a way of maintaining the fertility of the soil and restoring necessary nutrients without using chemical fertilizers. Next article What do you know about Zika Virus: Staff.
