Answer: Green manuring crop
Notes: Distribution of green manure, Dhaincha, has started in Tamil Nadu. Dhaincha is a tall annual herb, often grown in wet areas and heavy soils in India. It is used to feed livestock and improve soil quality. Green manuring involves growing leguminous plants and incorporating them into the soil. This practice enhances soil structure, increases water retention, reduces erosion, controls weeds, and helps reclaim alkaline soils. It also adds organic matter to the soil and boosts microbial activity.
