What are Green Manures?

Green manure refers to a specific type of crop cultivated with the intention of being incorporated into the soil to improve its health. These crops are grown primarily for the purpose of soil enrichment, and they are often left in their vibrant, green state before being tilled or used as mulch. I have found that planting green manure during the vacant areas of the farm, where no primary crops are growing, not only preserves soil structure but also offers a plethora of benefits, such as preventing erosion and retaining essential nutrients. Their root systems act as a natural form of ground cover, providing a protective layer for the soil.

By fixing nitrogen in the soil and inhibiting weed growth, green manure plants help contribute to the overall fertility of the farm. Their decomposing plant residues leave behind an organic material that enhances the organic content of the soil. The green manure mass is then incorporated into the soil, where it gradually transforms into rich organic material that enhances the overall quality of the land. This incorporation process makes a significant impact, as it improves soil structure, aids in retaining moisture, and creates a fertile environment for future crops to thrive.

Green Leaf Manuring

Green leaf manuring is a simple yet effective practice where farmers use fresh leaves and twigs from various trees, herbs, and shrubs to improve soil quality. Having worked with this method, I’ve seen the benefits of trimming and collecting leaves from forest trees or even those growing along field bunds and in wastelands. These collected materials are then applied directly to the soil as natural fertilisers or organic fertilisers, contributing a wealth of nutrients. This process not only enriches the soil but also aids in preserving its structure by adding organic content, making it more conducive to healthy crop growth. The beauty of green leaf manuring lies in its accessibility, as it can be done in similar locations where such plants grow abundantly, and it naturally enhances the farm’s soil without the need for synthetic chemicals.
