Abstract
The article presents the results of studies of the chemical composition of fresh cattle manure on straw litter, processed manure in the form of compost and granular organic-mineral fertilizer, and also presents data characterizing the level of heavy metals in organic-mineral fertilizers. It has been established that organic mineral fertilizers based on cattle manure have a high nutrient content. According to the chemical composition and content of heavy metals, organic mineral fertilizer meets the national standard of the Russian Federation GOST R 53117-2008 «Organic fertilizers on basis of waste of stock-raising. Specifications» and hygienic standards GN 2.1.7.-2041-06 «Maximum permissible concentrations (MPC) of chemicals in the soil».
