abstract:
The research was conducted in the years 1994-2003 in two rural drained catchments (the Olsztyn Lakeland), differing in the type of soil and the structure of land use. The amount of chemical erosion of phosphorus was calculated on the basis of P concentrations in monthly sampled water as well as in drainage discharges. A correlation was found between annual or seasonal precipitation amounts and the outflow of the component from the catchment. Export of the component from soil was several times higher in wet and normal periods in comparison to very dry and dry ones. Amounts of exported phosphorus compounds via drainage network from the rural catchments as related to the seasons create the following decreasing series: spring>winter>autumn> summer. Moreover, total phosphorus outflow was two times higher with regards to the increase in agricultural catchment use.
