Production of the pea-oats mixture under the influence of ultramicroelements

The production of green mass of the pea-oats mixture was estimated under the influence of treatment by the increased doses of ultramicroelements (As, Sb, Te, Tl, Cd, Bi, Sn and others). In field experiments on small plot it was shown, that foliar treatment by water solution of salts promote to raising of green mass crop to 40-50 %. The reason of toxicity of heavy metals is as a rule the excess of permissible content of elements in plants during foliar treatment or addition to soil. The empiric formulas and the intervals of permissible content of the element in plant were presented.
