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

The article presents the findings on use of foliar treatment with suspensions sapropel, vermicompost, diatomite conventional grinding and in ultrafine form. Fertilizers, ground to smallest particles deionized water under action ultrasound, have a high stimulating effect crop shown better results compared milled fertilizers. yield spring barley Prairia variety non-foliar these fertilizers contributed an increase grain up 22.1 %.
