A novel technique utilizing enriched 15N2 to trace nitrogen transfer in grass and legume mixtures

Abstract Legumes are a potentially important N source in pasture systems, but quantifying the transfer of biologically fixed N from the legume to the grass component is difficult. A greenhouse H-pot system was developed to directly estimate belowground N transfer from biological N2 fixation (BNF) us...
