Question

Why do leguminous crops not require such enrichment of the soil?

Answer 1

Gardeners can feed their families and enrich the soil by growinglegumes, such as green beans, soybeans, lentils and peas. Legumeroots produce their own nitrogen, which is a major fertilizer nutrient needed by all plants for growth. ... The bacteria take nitrogen from the air and convert it into a form theplants can use.
