Changes in the content of mobile phosphorus forms and their migration were studied in mineral meadow soil after application of artificial cattle urine to a number of locations in a pasture. Studies were carried out in three field experiments situated on black degraded earth in Falenty in 2004-2005. The amount of phosphorus released from soil (P-extr.) from under locations of simulated urination using artificial cattle urine due to mineralization depended mainly on the amount of nitrogen introduced with the urine. Soil moisture and temperature and the ambient temperature could also affect this process. The simulation led to the supposition that an intensive and inappropriate grazing system could result in large nitrogen inputs to the soil through animal faeces posing a serious risk of dissolved phosphorus penetrating to the ground water.
