The Comparative Efficiency of Organic, Mineral and Organo-Mineral Fertilizers for the Winter Wheat Grain Yield in the Forest-Steppe of the Volga Region

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions Volga forest-steppe. According to organic system, straw predecessor, green manure Biocomposite-correct were introduced into soil (typical medium-thick medium loamy chernozem) for mass (vetch-oat mixture). system included two options: applied together nitrogen a dose 10 kg per 1 ton zeolite enriched amino acids. fertilizers nitrogene phosphorus NPK content 16 ai/ha, carbamide potassium chloride. In addition, highly siliceous rock was as fertilizer. It found that use organomineral improves nutrient regime soil; terms nitrogen, arable layer, these options not inferior option fertilizers. When introducing acids, yield exceeded by 0.59 t/ha. contributes production environmentally friendly products
