Summary
Acetylene-reducing activity and populations of diazotrophs were estimated simultaneously in Giza soils after harvest of wheat and maize crops. Amendment of soil with residues of either crop together with flood irrigation enhanced the development of diazotrophs and nitrogenase activities in the soil. Bacterial numbers and acetylene-reducing activity decreased as soils dried following flood irrigation. Activities decreased progressively with each cycle of irrigation following the original incorporation of organic matter. Nitrogenase activity in the soil was greater in the cooler winter than in summer.
