Most of the nitrogen fixed during the season is removed from the field as grain. The stalks, leaves, and roots of grain legumes, such as soybeans and beans, contain about the same concentration of nitrogen as found in non-legume crop residue.

Which legume produces the most nitrogen?

Forage legumes, such as alfalfa and clovers, are the best crops for companion planting as they can fix substantial amounts of surplus nitrogen under the right conditions. Some of this excess nitrogen is released through the roots of the legume and is available in the soil for plant uptake through nitrogen transfer.
