This article presents an analysis of soil properties and the effect of fertilization balanced according to those properties on potato yield and chemical composition of tubers. The experiment was carried out in 1997-1999 in Dotnuva on different plots with a prevailing soil type of soddy gleyic podzolized and soddy calcareous podzolized with traces of gleyicity light loam soil. On the basis of the revealed regularity a conclusion was drawn that according to the totality of soil properties it is possible to predict the yield, obtained at average metereological conditions and to optimize fertilization for a programmed yield. Higher deviations of actual yield from the predicted or programmed one were noted only in a very droughtly year of 1999
