Green manure is a sustainable agricultural approach in which particular plants, usually legumes or grasses, are grown and then incorporated into the soil while still green and growing. This strategy naturally enhances soil nutrients in a variety of ways:

1.Nitrogen Fixation: Leguminous green manure crops like clover, peas, and beans have symbiotic partnerships with bacteria that fix nitrogen in their root nodules. The nitrogen levels in the soil are raised by these bacteria’s conversion of atmospheric nitrogen into a form that plants can utilize.

2. Organic Matter Addition: When green manure crops are incorporated or mulched, they enrich the soil with organic matter. This organic matter increases water retention, strengthens the structure of the soil, and encourages the growth of healthy soil microbes.
3. Nutrient Cycling: The breakdown of green manure crops releases nutrients into the soil, including micronutrients, phosphorus, potassium, and nitrogen. The necessity for chemical fertilizers is reduced by this organic recycling of nutrients.

4. Soil Erosion Control: Green manure crops’ deep root systems stabilize the soil’s structure and lower surface runoff, which helps stop soil erosion.

5. Improved Crop Yields: Green manure, by improving soil fertility and structure, can contribute to higher crop yields over time, especially when utilized in rotation with food crops.
