Influence of Sapropel, Diatomite, Brown Coal and Vermicompost in Normal and Ultrafine Forms on Productivity and Quality of Spring Barley

Abstract

The article presents the findings on the use of foliar treatment with suspensions of sapropel, vermicompost, diatomite of conventional grinding and in ultrafine form. Fertilizers, ground to the smallest particles in deionized water under the action of ultrasound, have a high stimulating effect on the crop and have shown better results compared to conventional milled fertilizers. The yield of spring barley of the Prairia variety non-foliar treatment with these fertilizers contributed to an increase in the grain yield of spring barley of the Prairia variety up to 22.1 %. Analysis of the structure of the yield and the chemical composition of grain has showed that diatomite, sapropel and especially vermicompost both in the usual form and especially in the ultradispersed form affect the change in indicators in comparison with the fertilized background.
