Green Manure Crops Gain Popularity for Organic Soil Improvement
Organic green manure crops, a method of organic soil improvement, are gaining attention among gardeners. These plants, when incorporated into the soil, enhance its quality, adding nutrients and preventing erosion. Experts like Nikki Tilley, author of six gardening books, recommend this practice.
Green manure crops can be incorporated into the soil by cutting and plowing or leaving them in the ground before tilling. The ideal time to turn them into the soil is just before flowering or after they have died off. Examples of green manure crops include annual ryegrass, vetch, clover, peas, winter wheat, and alfalfa. These crops add nutrients and organic matter to the soil, improving drainage and water retention, and preventing leaching, soil erosion, and weed growth. Legumes, like clover and peas, are particularly useful for garden areas needing additional nitrogen. The choice of green manure crop depends on the season, site, and specific soil needs. Cool-season grasses are suitable for fall or winter, while heat-loving crops are good for spring and summer.
Green manure crops, when used effectively, can significantly improve soil health and fertility. This organic method, popularized by agricultural pioneers like Sir Albert Howard and Justus von Liebig, is a sustainable way to enhance gardening success. Nikki Tilley and other experts recommend incorporating these crops into gardening practices for a healthier, more productive garden.
