The study concentrates upon evaluating the relationship between the content of phosphorus and potassium in the 0.01 mol/cubic dm CaCl2 soil extract and their concentration in the groundwaters. Significant correlations between P and K in the soil extract and their concentration in the groundwater were found for farms from Grodek and Dziarnowo and only for P in Malszyce (Poland). The physical and chemical properties of soil, such as pH value and C organic content have been influential on the appearance of significant correlations between P and K in 0.01 mol/cubic dm CaCl2 and their concentration in the groundwater
