Influence of agronomical methods on a state of heavy metals in leached chernozem. Gaidukova N.,G., I. A. Lebedovskiy. "Scientific Bulletin", VNIIMK, 2005, v. 1 (132). The influence of different agronomical methods on the content of the gross and mobile forms of manganese, copper, zinc, lead, cobalt and cadmium in low and subsurface layers of leached chernozems was investigated within the framework of agroecological monitoring. The influence of recommended and higher doses of applied fertilizers on the above mentioned elements was found out in research. There is an exceed of maximum allowable concentration of the gross forms of zinc, but the contents of their mobile forms is lower maximum allowable concentration, that ensures the receiving of ecologically clean products, but demands constant monitoring researches.
