PHOSPHATE AND AMMONIUM CONCENTRATIONS IN GROUNDWATER FROM PEAT SOILS IN RELATION TO THE WATER TABLE

摘要

Soils developed from low peat found in the Biebrza National Park in north-eastern Poland show that seasonal lowering of the groundwater table in peat soils can result in a measurable increase in phosphate and ammonium concentrations in the groundwater. The main reason for the very high concentrations of phosphate is the large amount of ammonium resulting from the ammonification process, the presence of which protects the phosphate from precipitation.
