The analysis showed that the regions of Poland varied as regards to crop production intensity as well as soil fertility and water quality. It was found that a negative effect of crop production on water quality is not significant at the present input level. There might be a threat to water quality only within the voivodeships of a relatively low crop production potential and high fertilizer rates i.e. Warminsko-Mazurskie, Wielkopolskie and Zachodnio-Pomorskie. The analysis proved that the threats to soil fertility in Poland are caused by the lack, not be the excess of elements
