Pulse and oilseed legumes such as soybeans and peanuts form associations with rhizobia bacteria, causing nodules to form on roots. In these nodules, the bacteria fix nitrogen (as N2) from the atmosphere and convert it into ammonia (NH3), which is used by the plant for growth. This nitrogen (N) fixed by the legume is strongly linked to the productivity of that crop. Also, the N-rich residues and excretions from the roots of the crops add to the N in soils and may be available for following crops. This can be particularly important in soils that are low in N, given the rises in costs of N fertilizer
