6518. Smith, S.C., D.F. Bezdicek, R.F. Turco, and H.H. Cheng. 1987. Seasonal N2 fixation by cool-season pulses based on several 15N methods.. Plant Soil 97:3-13.
Used 15N to determine N2 fixation by fababean, lentil, Alaska pea, Austrian winter pea, blue lupin, and chickpea. Mean seasonal N2 fixation by fababean, lentil, and AWP was near 80 kg N/ha, pea and lupin near 60 kg N/ha, and chickpea less than 10 kg N/ha. The net effects on the soil N pool ranged from 70 kg N/ha input by lentil to a removal of 48 kg N/ha by chickpea. Pulse crops often remove more N in the seed than they fix, leaving a deficit for the next crop. T: legume DM, total plant N, seed yield, seed N; N fixation values by different methods.
