Abstract: At a typical black soil leached when applying N50P60K50 under winter wheat and 8.3 t/ha of manure + N43 3P43 3K43 3 in crop rotations for the period releasing to a tube, the number of (NH4 + NO3) in the arable soil layer was within 15,5-16,0; P205 — 270-279; K20 — 93-95 mg/kg, which was independent of rotation. In the fruit-variable crop rotation against the background of the use of crop residues + N43,3P43,3K43,3 and N60P60K60 under winter wheat the number of (NH4 + NO3) amounted to 14,8; P205 — 268; K20 — 93 mg/kg
