The aim of the study is estimation the changes in chemical properties of orthic luvisols of Kaluszynska Upland during the last twenty years of their agricultural utilization. Comparing the results from 1995 with the results obtained in 1974 (collected during soil mapping) it is concluded an average decrease in pH(H2O) and pH(KCl) by about 0.5 unit to the level of 4.0. The organic matter content decreased in Ap horizons on average by about 20 percent. A very low to low content of magnesium and low content of potassium were observed, but phosphorus increased 2-3 times
