Ammonia oxidizing archaea (AOA) and bacteria (AOB) were measured in cropped soil. AOA greatly outnumbered AOB and varied over time within a maize cropping system. AOB were almost 10-fold lower in disk plots, but AOA did not differ. N rate had no or minimal effect on ammonia oxidizer abundance. Microbial community biomass was dynamic and responsive to date, tillage and N rate.
