Agroecological assessment of changes in cadmium content in spring barley plants under the influence of selenium and silicon

A large amount of agricultural land is located in close proximity to the metropolitan areas, it means near industrial enterprises and highways which giving rise inevitable soil pollution by heavy metals, most toxic them are cadmium, mercury lead. The plant products harvested from such areas frequently contains metals make unsuitable for human or animal consumption. Studies have shown that pre-sowing treatment spring barley seeds selenium silicon allows mitigate negative impact abiotic stresses on growth development, deliver crop yield level, laid down biology under these conditions - 3,7-3,9 t/ha. Moreover, this method reduces level cadmium accumulation finished (grain) 11-12% when growing soils with high concentration cadmium.
