Forms of nitrogen (N-NO_3, N-NH4^+, N-org) and phosphorus (P-PO_4^-3, P-org) were investigated in ground and surface water as well as in precipitation and run-off. The highest concentration of all the investigated compounds was determined in the drain and in run-off. This investigation shows that afforestations and small ponds function as very efficient biogeochemical barriers with regard to N-NO_3 - and P-PO_4^-3. They do not, however, limit the spread of P-org.
