The average proportions of denitrifiers within the total nitrate-reducing populations were 24, 34 and 73% and those of nitrate reducers within the total bacteria were 12, 39 and 42% for non-rhizosphere soil and rhizosphere soil of 0 N and 120 kg N wheat plants, respectively. Some positive correlations existed between soil moisture and nitrate-reducing and denitrifying bacteria. Maximal denitrifying populations were reached in the rhizosphere of flowering, N-fertilized plants after heavy rain.
