The influence of diet on the biological activity of the soil and the productivity of grain crops in the Prebaikalia

This article presents data on the general effect of foliar top dressing on the yield of cereals such as wheat, triticale, barley and oats on various backgrounds of mineral nutrition. The data on the biological activity of soils by the method of application analysis are also presented. The analysis of weather and agrochemical parameters of the soil, such as the amount of humus, the reaction of the soil solution, and the supply of nutrients that activate the activity of microorganisms and have a significant effect on the productivity of crops. During the research it was found that during the growing season, weather conditions and backgrounds of mineral nutrition had a significant impact on the rate of decomposition of linen. In addition, the influence of various species characteristics of crops on biological activity was noted. In the year of research, the logical effect of extra-root dressing on the studied cultures was not established. The maximum yield increase from the application of foliar top dressing was obtained on a variant of the experiment without the use of fertilizers.
