摘要

Our investigations were carried out in' the central part of Poland in the region known as Wielkopolska, distinguished, both in the past and now, by its intensive and well-managed agricultural economy. The research objects comprised mainly small watercourses and their catchment areas. The results of our studies revealed a favourable role of permanent meadows regarding the quantitative occurrence in open waters and absorption of the nitrate nitrogen, potassium, sodium, phosphorus, calcium, magnesium, chlorides, and sulphates by meadow complexes.
