Impact of organic fertilizers on radionuclide migration in gray forest soils

In field and laboratory studies on gray forest soils of the experimental field of the Institute of Agroecology and Environmental management of NAAS for eight years (2004–2011 years) we studied the effect of new domestic organic fertilizers Vitalyst, Oasis, Dobrodiy on grain quality and yield of different crops including corn. The use of organic fertilizers increases the yield of grain corn by 13.2–37.9%, and improves the quality of crops, protein content in grain corn increases by 0.97–1.20%. During the application of organic fertilizers hydrolytic acidity of soil, humus content and heavy metals were on the level of control, it positively influenced the content of amphoteric bases Ca2+ and Mg2+, increasing the content of mobile forms of phosphorus and potassium and helping transform soluble phosphorus and potassium in mobile forms. The use of organic fertilizers increases the yield of grain corn by 13.2–37.9% and improves product quality of crops, protein content in grain corn rose to 0.97–1.20%. The content of mobile forms of phosphorus and potassium in the soil does not decrease with increasing productivity, and even slightly increased. It has been practically proven environmental and economic feasibility of new organic fertilizers Vitalyst, Oasis, Dobrodiy. The use of organic fertilizers reduces the transfer of radionuclides in the production of crops. The content of mobile forms of phosphorus and potassium in the soil were higher, even with an increase in yield, biota functioned more actively, soil phytotoxicity decreased. We have proven environmental and economic feasibility of new organic fertilizers Vitalyst, Oasis, Dobrodiy
