Abstract
A micrometeorological technique was used to calculate the net transfer of NH3 between a corn crop and the atmosphere. On the 10 days of measurement, there was continual interchange of NH3 between crop and atmosphere with a strong indication of a diurnal cycle. Ammonia absorption by the plant‐soil system (downward transfer of NH3) predominated when the soil surface was dry, but sustained losses of NH3 (upward transfer) occurred when it was moist. Net absorption rates of 6.6 g N ha−1 hour−1 were calculated in the former period, and net losses of as much as 27.6 g N ha−1 hour−1 in the latter.This publication has 1 reference indexed in Scilit:
