The interrelation of regulation methods of soil fertility, agrochemical and agro-physical indicators of dark-brown soil was determined by the complex studies. The increase of the humus and available phosphorus content in the soil was noted at the application of organic fertilizers (manure, siderates), the increase in structural composition was observed. Productive moisture additionally collected in the soil. The use of organic and siderate-organic fertilizers promoted the increase in productivity of grain crops from 16.0 to 33.1% in comparison with the control (without fertilizers).
