Abstract

Following the scientific management of organic manure (poultry) may contribute to reducing environmental pollution and human health, as the current study was conducted with the aim of recycling poultry manure accumulated in the field of poultry farming at the research station - Faculty of Agriculture - Karma site and the impact of varying fermentation durations on organic manure, specifically animal (poultry manure) fermented by different fermentation methods and its impact on the rest of the factors to produce highly decomposed organic manure free of pathogens. Several traditional fermentation methods (compost and water immersion) were followed. and modern (bioreactor), and for a fermentation period of 90 days with an estimate of most of the qualitative characteristics of the organic manure produced and within periods of 15 - 30 - 45 - 60 - 75 - 90 days. The results of the experiment of incubation of poultry manure showed that all the studied traits have changed with the progress of fermentation time and in the same direction, the results demonstrated that fermentation in the bioreactor unit has given the highest values of total nitrogen, total phosphorus and potassium 32.53, 16.72, 20.86, g.kg-1 for the elements mentioned sequentially, while the lowest values of pH 6.68 and C/N ratio 9.96 compared to other fermentation methods.
