Study of the effectiveness of mineral fertilizers and the biopreparation Humimax on the productivity and quality of oat grain cultivated on soddy-podzolic sandy soil

Abstract

The results of studies on the effect of different doses of mineral fertilizers and the biopreparation Humimax on the productivity and quality of oat grain when cultivated on soddy-podzolic sandy soil with a pollution density of 20 or more Ci/km2, and on the transfer of radionuclides into oat grain are presented. It has been established that the use of the biopreparation Humimax provides an increase in the yield of oat grain by 23%. Consistently increasing doses of potassium in the composition of NPK, both with a separate application and in combination with a biological product, reduced the specific activity of 137Cs in oat grain by more than 3 times. The use of the drug Humimax on all backgrounds of fertilization provides an increase in the content of crude protein in the grain.
