Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield.
What is crop rotation and why is it important class 8?
Crop rotation: Different crops require different nutrients. Therefore, farmers plant different crops each season. This is called crop rotation. It prevents depletion of nutrients in the soil.
What is crop rotation for Class 10?
Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It helps in reducing soil erosion and increases soil fertility and crop yield. With crop rotation, particular nutrients are replenished depending on the crops that are planted.
What is Green Revolution class8?
green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century.
How does crop rotation help the environment?
By adding small grains and forages into rotations, less fertilizer is required and less pollution is emitted. The addition of a single small grain crop can reduce fossil fuel use, pollution and damages by about one-half, according to the research.
Where does crop rotation occur?
Crop rotation is a common practice on sloping soils because of its potential for soil saving. Crop rotations can be used to improve or maintain good physical, chemical, and biological conditions of the soil. They can be used to reduce the average rate of erosion from a field.

How is crop rotation useful class 9?
The process of crop rotation is primarily used to replenish the different types of nutrients by cultivating different crops. It increases soil fertility and in turn increases the yield of the crops. Crop rotation helps to reduce soil erosion and restore the physico-chemical balance of the soil.
What is crop rotation Byjus?
Crop rotation method involves growing of set of crops in a regular succession over a same piece of land (field with) in a specific period of time.
