Removal of ammonia from poultry manure by aluminosilicates
Journal of Environmental Management, 2016The aim of the study was to test the possibility of using aluminosilicates as natural sorbents of ammonia from poultry manure. The ammonia-absorbing properties of sodium bentonite and zeolite were confirmed in ex situ conditions. The most significant reduction in the level of ammonia with respect to the control was noted for 2% bentonite and 1% zeolite.

Fermentation of poultry manure for poultry diets
British Poultry Science, 19771. The fermentation of poultry manure in an attempt to increase its value for poultry diets was studied. 2. Microbial strains for the efficient elimination of uric acid were isolated. 3. Suitable, cheap carbon sources (methanol, glycerol, glucose) were tested in attempts to increase cell yield. 4.

Journal of the Science of Food and Agriculture, 1973
AbstractExamination of samples of deep litter poultry manure which caused growth deformation in vegetable crops resulted in the isolation of a potent phytotoxic compound. The chemical properties and symptoms produced by tomato plants grown under hydroponic conditions, showed that it was not 2,4‐D as suggested by other workers but a nitrogen ...

Ecotoxicity Bioassays on Leachates from Poultry Manure
Bulletin of Environmental Contamination and Toxicology, 2013The main aim of this study was to evaluate the toxicity of different poultry manure landfill leachates, using a well-known toxicity test system (MS3). The bioassay was made using a battery of toxicity tests including acute toxicity with crustacean (Daphnia magna), algae (Chlorella vulgaris) and the in vitro toxicity test with the fish cell line RTG-2 ...

Anaerobic fermentation of poultry manure
Applied Energy, 1976Abstract Although both in nature and in conventional anaerobic decomposition process plants, acidification and gas production occur simultaneously, the rates of methane production and waste stabilisation can be enhanced by arranging that the process occurs in two stages.

Experimental Research of Combustion of Poultry Manure
2021This research addresses two waste management (poultry manure) objectives: reducing environmental impact through combustion, and energy generation. Poultry industry waste is produced in large amounts and cannot be always used as a fertilizer. Thus, poultry waste storage needs large sites, but if they are improperly designed could affect the phreatic ...

Animal Manures as feedstuffs: Poultry manure feeding trials
Agricultural Wastes, 1983Abstract The utilisation of dried poultry manure as a feedstuff was critically evaluated based upon feeding trial results reported in the literature. The assessment indicated that this material can have value as a feedstuff. The maximum and optimum levels of incorporating dried poultry manure into laying hen and ruminant rations, on the basis of ...
