Abstract
The article presents the results of studying the toxic levels of mobile copper in typical chernozem by doing model field experiments with artificial soil contamination with copper sulfate at a level of 2 MPC Cu, 4 MPC Cu and 10 MPC Cu. It was shown that this increased the content of mobile copper from 1.4 (2 MPC Cu) to 2.0 times (10 MPC Cu) when copper was extracted from the soil, respectively, with an acetate-ammonium buffer solution of pH 4.8 and 1n HCl solution. The latter was accompanied by the loss of almost a third of the spring wheat yield (29%) and an increase in the entry of the element into produce (grain). The application of diatomite to the soil (dose 5 t / ha) as a detoxifying agent contributed to a decrease in the level of copper in the spring wheat produce by 8 (2 MPC Cu) and 35 (10 MPC Cu)%.
