After seven rotations in a long-term three-field trial (wheat, maize and spring barley), the chernozem soil is rich in micronutrients. The level of readily available phosphorus in fertilized treatments has increased statistically significant in relation to the non-fertilized one. The level of readily available potassium in mineral fertilizer treatments that included the incorporation of harvest residues has increased significantly relative to the control treatment and mineral fertilizer treatments without harvest residues. There are no significant differences in microelement content between the different fertilization treatments relative to the non-fertilized treatment. Yield losses in the non-fertilized treatment varied according to the crop species, ranging from 49% in spring barley (the first and fourth rotation) to 10% in maize.
