Abstrakt: In a vegetative experiment on polluted 137Cs soddy-podzolic soil with peas (Pisum sativum L.) of the variety Pharaon, a comparative assessment of the effect of the organo-mineral fertilizer SUPRODIT-M, organo-mineral complex GEOTON, and mineral fertilizers (NPK and azofoska) on the content of radionuclide forms in the soil, soil biological activity, productivity, and quality of peas was undertaken. Mineral fertilizers and SUPRODIT-M were introduced into the soil, and plants were treated with the preparation GEOTON two times during the growing season. The effect of various types of agrochemicals was evaluated by changes in the potential activity of respiration (the rate of CO2 emission in the soil), the potential activity of soil denitrification, the content of 137Cs forms in the soil, the transfer factor (Tf) of 137Cs in plants, the yield and indicators of grain quality, and vegetative mass of peas. The use of SUPRODIT-M helped to reduce the content in the soil of 137Cs for the most accessible for plant exchange and mobile forms compared with the use of mineral fertilizers. It is known that leguminous crops (Fabaceae) under conditions of radioactive soil contamination accumulate 137Cs in the yield up to ten times more than spring and winter cereals. Adding NPK to the soil stimulated the rate of CO2 emission in the soil under the peas compared to the control. Application of SUPRODIT-M and azofoska reduced the potential activity of denitrification of the soil. SUPRODIT-M increased the seed yield and vegetative mass of peas. Treatment of vegetating plants with GEOTON against the background of SUPRODIT-M additionally increased the yield of peas compared to the option without treatment and relative to the control. The greatest yield of peas is obtained from the use of GEOTON against the background of mineral fertilizers. SUPRODIT-M limits the transfer of 137Cs from the soil to plants compared with mineral fertilizers. Introduction of SUPRODIT-M contributed to a significant reduction in the removal of 137Cs by peas relative to the control. The use of GEOTON against the background of SUPRODIT-M further reduced the removal of 137Cs by the plant and the vegetative mass compared to the variant without treatment and the relatively absolute control. SUPRODIT-M had a positive impact on the indicators of quality of the seed and the vegetative mass of peas. [ABSTRACT FROM AUTHOR]
