Nowadays, the proliferation of organic wastes is attributed to the scaling up of poultry farms, and these organic wastes generate a plethora of ammonia losses, which in turn jeopardize atmospheric quality. These organic residues with regard to their use as nutrient source and soil conditioners in agricultural areas is considered one of their recycling ways and their fertility value is contingent on the extent of plant nutrients which lies in organic fertilizers obtained from these organic wastes. Therefore, the aim of this study was to investigate the effects of zeolite, sulfuric acid and gypsum applications on nitrogen losses as ammonia gas (NH3) from chicken fresh manure. The experiment was carried out in a closed system under laboratory condition whereby two different concentrations (1 and 2%) of zeolite, gypsum and sulfuric acid were separately applied to 250g of chicken fresh manure based on oven dry weight. The prepared samples were left to the incubation for 6 days and then daily and total nitrogen losses as NH3 were measured by vacuuming at certain intervals. The experimental results showed that the addition of zeolite, gypsum and sulfuric acid at the rate of 1% substantially decreased the nitrogen losses in gas form by 32%, 53.31% and 52.29% respectively, while the application of zeolite, gypsum and sulfuric acid at the rate of 2% significantly reduced losses by 54.23%, 58.87% and 62.09% respectively.eninfo:eu-repo/semantics/openAccessAmmonia volatilizationchicken manuregypsumsulfuric acidzeoliteArticle28541014105WOS:000471836900057N/A
