The change in the potential and effective fertility indicators of the agrogrey soil under the influence of biohumus, azophoska and mixtures based on them are considered in the article. It is revealed that the biohumus application facilitates the increase of С org content by 1,3 times, hydrolys able nitrogen amount by 1,2-1,5 times and mobile phosphorus content by 2,4-2,8 times depending on its introduction doze compared with the control group. It is shown that the highest corn yield is formed under the biohumus influence introduced in the amount of 6 t/ha.
