The action of green manure of legumes is a complex and extremely efficient process for increasing soil fertility. In organic farming, legumes are famous for their ability to fix atmospheric nitrogen. This is derived from the mutualistic symobiosis between the roots of plants and some species of bacteria naturally present in the soil: the rhizobia.

These rhizobes capture the nitrogen present in the atmosphere and fix it thanks to the action of a particular endogenous enzyme, nitrogenase. This activity of the rhizobia is enhanced in the roots of legumes with which the bacteria activate a symbiotic relationship.

Thanks to this, the plants benefit from the nitrogen fixed for their green mass. At the same time, the carbon compounds from plant photosynthesis are used by bacteria as an energy source to fix nitrogen. A virtuous, symbiotic circle is created between plants and bacteria, from which the soil and the vines benefit.
