Influence of indexes of fertility of soils on quality of grain of winter wheat on sod-podzolic soils of Polisya

Abstract

Goal. Determine the influence of soil parameters (humus, pH, mobile phosphorus and potassium compounds) on the protein content, gluten and vitreous appearance of winter wheat grains on soddy podzolic soils of Polissya. Methods. Mathematical-statistical processing of the relational database of field experiments with fertilizers. Results On the sod-podzolic soils of Polissya the quality of winter wheat grain depends on the content of humus and the degree of acidity of the soil solution. Conclusions The norms of influence of soil fertility indices on grain quality are established.
