This research is devoted to ecological problems associated with the development of poultry farming in Ukraine. It provides practical approach to the reduction of ammonium emissions from poultry farms, which results in an opportunity to produce organicmineral fertiliser. Organic-mineral fertilisers obtained
this way were tested in field.
The methods of laboratory studies found the opportunity to intensify the process of methane fermentation which is used in the complex fertilizer technology. To intensify fermentation it was suggested to reprocess the mixture by chemical and mechanical ways that consists in the preliminary dispersion. Thus, the duration of mixture methanation process in mesophilic regime has been reduced by more than a half. The functions have been obtained and can be used to select the method of fermented mixture preprocessing in industry.
