Green manure is created by growing specific quick-growing plants, such as sunn hemp or guar, and then plowing them into the soil before sowing crop seeds. As these plants decompose in the soil, they enrich it with essential nutrients like nitrogen and phosphorus. Additionally, green manure improves soil structure, enhances water retention capacity, prevents soil erosion, and promotes beneficial microbial activity, making the soil more fertile for future crops.
