Ecotoxicological evaluation of the preparation "Agrobionov" on the content of heavy metals and radionuclides in black earth of common and oil flax plants

Abstract

This article presents the results of bioinduction of "Agrobionov" product to the physiological parameters of oil   flax seeds, and also provides an ecotoxicological assessment of "Agrobionov" product usage according to the content of heavy   metals and radionuclides in the soil and oil flax plants. Laboratory and field experiments were carried out. The objects of   study are ordinary in black earth of common and flax oilseed variety "Severny". Laboratory germination of seeds, the length of   seedlings, the length of the submuscular knee was determined according to the Interstate standard "Seeds of agricultural crops"   SAUS 12038-84. The content of heavy metals (SAUS 50686-94-SAUS 50683-94) and radionuclides in the soil and seeds of oil   flax was determined by inversion voltammetry. The test "Agrobionov" product has a stimulating effect on the growth processes   in oilseed flax seeds, as well as the content of heavy metals and radionuclides in the soil and seeds when using various doses   from 100 to 500 kg / ha of the product did not exceed the maximum permissible concentration.
