AN ENVIRONMENTALLY FRIENDLY SYSTEM OF FERTILIZERS IN THE CULTIVATION OF SPRING BARLEY
Studied the separate and combined application of vermicompost, fertilizer Siliplant and growth regulator EPIN on the food regime of the soil and yield of spring barley. Increasing nitrate and ammonium nitrogen in soil available phosphorus and potassium have been found in variants with the application of vermicompost. Higher additional grain yield of spring barley obtained by the integrated action of the studied factors.
