Trying to find the best solution for the ecological problem of karst zone (i.e. protection of surface and ground water from agricultural activity) it is important to determine the migration extent of plant nutrients leached from the soil into the streams and ground water depending on the type of land use. The paper presents the results of the studies carried out in two vicinities of intensive karst zone in Birzai district. The obtained results show the influence of drainage water on the quality of stream water in drained areas. It has also been determined that drainage water quality is influenced by soil forming rocks as well as by the type of land use. In the failures of karst zone, as well as in arable land the quality of ground water is worse, especially when ground water is found near the ground surface.
