Abstract

Studies conducted to study the effect of the use of combinations of bird droppings and mineral fertilizers, organic fertilizers on the yield of grain crops in a crop rotation showed that this technique can significantly increase the productivity of arable land. On average, over three years of research, the increase in the use of mineral fertilizers and bird droppings was 45.3–46.6 % higher than in the variant without fertilizers. The use of organic mineral fertilizers obtained on the basis of bird droppings with mineral enrichment highly effective intake, grain productivity of spring wheat and oats even in adverse weather conditions exceeded the control options by 44–47 %. Conducted comparative analysis of the options with mineral fertilizers and organomineral fertilizers showed that the latter are not inferior in direct effect, and in some cases even superior to the mineral counterpart. Comparative production tests have confirmed the significant economic efficiency of using complex organomineral fertilizers compared to its industrial mineral counterpart.
