The research results concerning microstructure and chemical composition of selected post-processed poultry beddings derived from industrial-scale poultry breeding are presented. It was found, that the proper trend is providing the optimal conditions in respect to bred-animals comfort. The highest concentration of biogenic elements — especially nitrogen and potassium — was observed for the samples of poultry manure premixed with the straw. High quality of bedding biomass influences the inhibition of poultry-manure decomposition processes advantageously. In effect, biogas yield increases (due to C/N adjustment), in spite of the fact that increase in ammonium nitrogen concentration simultaneously inhibits the methane fermentation process.
