Green manure refers to the practice of growing certain plants like sun hemp or guar before sowing crop seeds, which are then plowed into the soil while still green. These green plants decompose in the soil, releasing nutrients such as nitrogen and phosphorus, thereby enriching the soil fertility.

Green manure refers to crops grown specifically to improve soil fertility. Typically, legumes like clover or grasses like rye are planted and then plowed into the soil before reaching maturity. As they decompose, they release nutrients like nitrogen, phosphorus, and potassium, enriching the soil. Additionally, green manure adds organic matter, improves soil structure, enhances water retention, and promotes beneficial microbial activity, fostering healthier plant growth.
