Pollution of groundwater due to nitrate is a serious problem in Poland. A significant part of this pollution originates from permanent grassland. The experimental results from four experiments conducted near Warsaw were compared and supplemented with the simulation made by means of the CREAMS model. A good agreement was found between the experimental and the simulated balance of nitrogen as well as chloride. The estimated nitrate nitrogen concentration in percolated water was between 10 and 90 mg N/l, which presents a real danger to the quality of groundwater. The obtained results ascertained that the CREAMS model is a proper tool for forecasting the nitrogen balance on permanent grassland, particularly the losses of nitrogen due to nitrate leaching. The chloride used as an experimental and/or calculated tracer to the nitrogen balance was shown to be advantageously valuable.
