Nitrogen in crop rotation with legumes

In organic stock-less farming systems, nitrogen has to be provided by cultivation of nitrogen fixating plants (legumes) in the crop rotations. The conventional farmers also concern about the utilization of nitrogen from legumes. Our research deal with the introduction of vegetable legumes in production schemes to enhance the sustainability of agricultural systems and improve the yield and economic benefit.
