Municipal wastewater treatment effluents were applied to a field of nearly waterlogged peat soil to determine the removal of phosphorus and nitrogen by the soil. After application of effluents, phosphorus fixation decreased but nitrogen removal increased. In laboratory experiments on drained samples of the soil, phosphorus fixation improved greatly to between 95 and 99 percent, but severe nitrification and leaching persisted. An aerobic (drained) system would be more advantageous for actual application, provided that proper management practices were used.
