Nitrogen fixation and transfer in vetch and vetch-oats mixtures

15N-labelled organic matter and ammonium sulphate fertilizer (20 and 60 kg N ha −1) were applied as 15N sources to estimate N 2 fixed in field-grown pure vetch ( Vicia sativa L.) and vetch grown in two mixtures with oats ( Avena sativa). The decline in 15N enrichment in the soil during the seven seq...
