Abstract (English):
The content of mobile forms of heavy metals in agricultural soils in the south of Primorsky region with the introduction of biochar in doses of 1 kg/m2 and 3 kg/m2 was studied. Where are no excess of maximum permissible concentration in agricultural soils. Biochar in doses of 1 and 3 kg/m2 is able to reduce the content of heavy metals in some elements (Cd, Zn, Cr, Ni, Cu, Fe, Mn).

Keywords:
heavy metals, agrosoils, biochar, mobile forms, Far East of Russia
