Nitrogen mineralization and water-table height in oligotrophic deep peat

  title={Nitrogen mineralization and water-table height in oligotrophic deep peat},
  author={Berwyn L. Williams and Ron E. Wheatley},
  journal={Biology and Fertility of Soils},
Peat cores, 0–60 cm depth, were taken on 14 occasions from three experimental plots where the water levels in the surrounding ditches had been artificially controlled for 14 years at 0, 20 and 50 cm below the surface. Numbers of aerobic and anaerobic ammonifying bacteria in the profile were significantly increased (P< 0.05) by lowering the water level from 0 to 50 cm. These increases occurred mainly in the surface 20 cm horizon, where 80%–90% of the ammonifying bacteria in the profile occurred… CONTINUE READING
