Question

b. What is crop rotation? How does it help in replenishment of the soil ?​

Answer 1

Answer:

Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons.

After the harvesting of any cereal crops such as we leguminous plants are grown on the field such as peas. microorganism or bacteria called rhizobium lives in the roots of leguminous plants and converts nitrogen into nitrates once the cropped the leguminous crop is cut the roots are left in the soil the decompose and the night rates are released into the soil which helps in the replenishment of the soil with nitrogen. nitrogen is one of the most essential nutrient that is required for the plants growth and it is also and inorganic nutrient

Answer 2

Answer:

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. 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 is beneficial to farmers as they use crop rotation to improve soil nutrients, foster soil quality, minimize soil erosion, and to increase water efficiency. A good rotation using nitrogen-fixing crops like beans helps to sustain farms, increasing productivity and lowering input costs.
