The aim of the study was to test the effect of system management in the buffer zone on groundwater quality. The study was carried out in the catchments of Lake Niepruszewskie (Poland). Cropping structure, fitosociological survey of the buffer and littoral zone were investigated in 2000-02 and 2005-06. The highest concentration of nitrate and phosphates in the groundwater were found on cultivated fields and significantly decreased in direction to the littoral zone. The lowest values of the measure parameters were detected in the meadow and littoral zone during growing and non-growing seasons. Nitrate content in the water decreased approximately 95 percent, phosphates 47 percent in direction: arable field-meadow-littoral zone
