摘要
Influence of fertilizers application on the change of indexes of soil quality is studied. As a result of experiment for a period of 2005-2009 we established that the productivity of agricultural plants is multiplied under applying chemical matter in soil. The mobile forms of microelements are accumulated; indexes stipulating exchange processes in soil diminish. There are tendencies to oxidization and toxicity of land arable layer. Quality of land is appraised according to the 100 - grade scale with a correction factor by the salt pH for the forest - steppe - 0.96. As a result the quality is decrease on 9.3 %.
