Temporary pastures, with the presence of legume species within the floristic structure, produce important amounts of biologically-fixed Nitrogen (BFN), which partially is used in the increase of the forage biomass yield, and partially remains in the soil for the next crops in the rotation. The results of the researches carried out made evident birdsfoot trefoil’s contribution, cultivated in association with perennial graminaceous, to the provision with biological Nitrogen of the temporary pastures. Under such conditions, birdsfoot trefoil leads to the achievement of a BFN amount of 70-96 kg/ha/year, and each percentage of participation leads to the achievement of an average of 2.58 kg/ha/year biological Nitrogen.
