Abstract The paper analyzes the changes in the main parameters of fertility indices bent, such as acid-base properties, which in modern terms of use soils are particularly important because of their acidification. In this paper, scientifically substantiated and proved the possibility of reducing the negative impact of various factors on the acid-base properties, through the use of periodic liming. Established that the acid -base properties of podzolic chernozem has significant influence fertilization system. On the basis of studies have shown that the mineral fertilization system most significant effect on soil acidification, and thus offset the acid- base balance towards acidification. Based on the investigations, recommendations for improving the acid-base properties have provided a scientific basis for the development of measures to improve the properties of the soil, which ultimately will provide not only improve soil properties but also ultimately increase productivity crops.
Key words soil fertility, acid-base properties, soil acidity, the amount eaten bases, cation exchange capacity, soil fertility, land degradation, soil decalcification
