The value of biological N fixation in sustainable biomass production systems should not be underestimated. Our objectives were to determine 1) the N fertilizer replacement value of kura clover (Trifolium ambiguum Bieb.) grown with prairie cordgrass (Spartina pectinata Link.) and 2) the effect of initial prairie cordgrass density on total production. Plots were established inIllinois, Minnesota, South Dakota, and Wisconsin, USA in 2010. Kura clover was transplanted on 30-cm centers while prairie cordgrass seedlings were...
