The article is devoted to the problem of poultry litter processing for its further utilization and application as a fertilizer. In the last decade, there has been an increase in the specific weight of poultry meat in the scale of livestock production, while the total number of poultry grown on different farms in the Penza region has increased from 9749.5 thousand to 15130.5 thousand. Currently, the annual total output of litter on the poultry farms is about 560 thousand tons, that could lead to environmental pollution in the surrounding area. Litter from local poultry farms contains a high content of nutrients necessary for plants (Ntotal up to 5.7%, P2O5 up to 5.6%, K2O up to 4.4%), that could be used as organic fertilizers or the main component in the production of organomineral fertilizers after composting.
Turkey litter generated at agricultural plots of PenzaMolInvest LLC is characterized by a high content of nutrients and after preliminary fermentation could be used to obtain granulated organic and organomineral fertilizers. Granulation of turkey litter after five months of natural composting at storage sites in pure form and with the addition of mineral components (defecate, phosphate flour or wooden plants’ ash) made it possible to obtain organic and organomineral fertilizers with high properties: nitrogen content of 2.1-4.1%, phosphorus content of 1.6-5.2%, potassium content of 1.7-4.5%, pH of 6.5-8.8, organic carbon content of 29.4-43.3%.
Keywords: poultry litter, chemical content, organomineral fertilizer, agrochemical composition of fertilizers.
