The article shows the effective and potential fertility of leached low-humus, low-power medium-loamy chernozem under the conditions of a stationary field experiment at the Central Experimental Field of the Kurgan Research Institute. Two technologies are characterized. In the first part of the experiment, the crop rotation is corn-wheat-wheat-oats with annual plowing, in the second part-permanent wheat on a stubble background. The first technology was distinguished by a higher effective fertility, a large number of plant residues, due to which its advantage was manifested in the content of humus. The fertilizer increased the productivity of agricultural crops. In increasing crop yields, the use of N40P20 was economically and environmentally optimal. The positive effect of fertilizers on the humus content in the soil layer of 0-20 cm was manifested when applying N50-75Р in the first part of the experiment and N40-60P20 in second part, which was not observed with unilateral nitrogen fertilizer and the use of dozes N25-20P.
