Green manuring involves incorporating green plant matter into soil to improve its physical, chemical, and biological properties, acting as a natural fertilizer that enhances soil fertility, structure, and water retention, while also suppressing weeds and soil-borne diseases. This sustainable practice increases organic matter, boosts microbial activity, reduces the need for synthetic inputs, and contributes to carbon sequestration, making it a valuable tool for sustainable and resilient agriculture, though its effectiveness can vary based on crop choice and environmental factors. The benefits of green manuring can vary depending on the specific green manure crop chosen, the soil type, and the overall management practices employed by the farmer. Green manuring (GM) crops generally have a considerable amount of biomass which comprises of aboveground and belowground biomass. They also have the ability to increase solar energy harvest and C flux into the soil and provide food for soil macro- and micro-organisms. Therefore, present review article is written to collect all possible knowledge and know about of green manures at one platform.
