Information on the amount and proportion of alfalfa (Medicago sativa L.) N derived from symbiotic N2 fixation is required in order to exploit this source of N in alfalfa-weeping lovegrass (Eragrostis curvula Schrad Nees) pastures in semiarid Argentina. A field experiment was conducted to determine N2 fixation by a legume grown alone or in two different… CONTINUE READING
