Stock-free farming or veganic gardening is a way to grow crops without using GMO seeds, artificial chemicals, manure, or animal parts including bone, blood, and fish meal. This type of farming uses mulch, vegetable compost, crop rotation, and other techniques.
In addition, a cover crop called green manure like soybeans, clover, millet, and buckwheat can be plowed under to add nutrients to the soil. Green manure benefits the soil by replacing nutrients, improving structure, and increasing organic matter content. In addition, green manure is used to break up the soil and put nitrogen back into the ground.
