Abstract

The article presents the results of research of chemical composition of chicken manure after its low-temperature vacuum drying and processing of organic raw materials by biofermentation in specialized facilities with active aeration of organic mass. Organic fertilizers based on chicken manure obtained as a result of temperature drying in a vacuum and active aerobic fermentation have a high content of basic nutrients: total nitrogen, phosphorus, potassium, trace elements: copper, zinc, manganese, iron, necessary for plants and a minimum content of heavy metals: cadmium, nickel, lead, mercury, which is below the maximum permissible, approximately permissible concentrations of chemicals in soil in accordance with hygiene standards.

Keywords
