However, most indicators remain within the conventional MPC. The content of nitrate ions increased by 1.2-1.4 times as compared to the period before 2014 in the water sources of the landscapes. By-products of winter wheat were also found to have a tendency to increase the lead and cadmium content when grown on farmland, but the heavy metal content of winter wheat grains did not exceed the MAC for adult nutrition. The greatest decrease in the inflow of VM into winter wheat grains was with the complex application of Polymixobacterin and Stimpo biostimulator. In this embodiment, the lead content decreased by 2.3 times, cadmium by 1.8 times. Biological absorption coefficient on control was 0.47 for Pb, 0.11 for treatment, 0.54 and 0.29 for Cd, respectively. The use of biohumus ensured a 9.6-11.0% increase in soil biological activity. With the introduction of biohumus, the content of easily hydrolyzed nitrogen increased by 13–21 mg / kg (9.6–15.6%), mobile phosphorus - by 17–22 mg / kg (14.2–18.3%). It has been established that the mineral nutrition system leads to an increase in the number of mobile forms of HM in the soil, which increases the risk of contamination of grain with these elements (lead content increased by 0.6 mg / kg against control). Due to the organo-mineral nutrition system with the introduction of biohumus in the arable soil layer, the content of mobile forms of HM decreased. In the presence of biohumus, the content of mobile forms of copper, zinc, and lead decreased the most, by 37.2; 36.2 and 23.6%. Scientific and practical recommendations on the reclamation of the territories that have been destroyed in the ATO zone have been developed. Product Description popup.authors Viniukov Oleksandr O.
