HORTICULTURE

Detailed explanation-1: -this process is called as crop rotation. this helps in the replenishment of the soil with nitrogen.

Detailed explanation-2: -each crop uses more of some nutrients and less of the others. farmers, therefore change their crops in each season so that the soil is not depleted of any particular nutrient. this is called crop rotation. for example, wheat or rice users up large amounts of nitrogen from the soil.

Detailed explanation-3: -The leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil. When the cereal crops like rice, wheat, maize are grown in the soil, it uses up a lot of nitrogenous salts from the soil. If another crop of cereal is grown in the same soil, the soil becomes nitrogen deficient.

Detailed explanation-4: -Rotating crops can have important production benefits such as increasing yields, improving nutrients and organic matter in the soil, and it can help disrupt the lifecycle of crop pests, reducing chemical use.
