Abstract: Results of the influence of chalk and mineral fertilizers during 15 years at the rates of exchange and hydrolytic acidity of sod-podzolic sandy loam soil were showed. The behavior of the calcium content in the first meter of soil has been considered. The coefficients of correlation and regression for the relationship between the exchange and hydrolytic acidity were determined.
