Abstract
This article presents the results of a field experiment on obtaining environmentally friendly products from sugar and fodder beets in conditions of zinc contamination. It was found that various intensification factors during the cultivation of sugar and fodder beets significantly change the agrochemical and agroecological properties of sod-medium podzolic sandy loam soil. The zinc content in sugar and fodder beets was almost two times lower within the treatments with the simultaneous introduction of lime as N60P60K60 + Zn + lime and N60P60K60 + Zn + lime + manure. Liming significantly increased the yield of products. In general, using a fairly minimal set of intensification factors on sod-podzolic soils without a combination with supporting liming caused the suppression of sugar and fodder beets on sod-podzolic soils under conditions of zinc contamination. Agroecological regimes were changed quite pronouncedly on soddy-podzolic soils of light granulometric composition, susceptible to zinc pollution, when lime fertilizers were applied, which makes it possible to reduce the mobility of zinc in the soil environment. The introduction of dolomite flour in the treatments N60P60K60 + Zn + lime and N60P60K60 + Zn + lime + manure reduced the translocation of zinc in the soil-plant system within concentrations above the established norms. However, in the production of fodder beets, this effect was established only in the treatment N60P60K60 + Zn + lime + manure. Thus, obviously the application of mineral fertilizers in combination with liming and manure as N60P60K60 + Zn + lime and N60P60K60 + Zn + lime + manure on sod-podzolic soils of light granulometric composition in conditions of zinc pollution make it possible to obtain environmentally-friendly products of sugar and fodder beets due to the negative impact reduction.
