The article presents the results of Efluent organic fertilizer research. We used pig manure to obtain biomass (residues); it also provided biogas production after digestion. We used a biogas system located in LLC Organic-D for fermentation of biomass, it is located in the village of Sutysky, Tyvriv district, Vinnytsia region, Ukraine. The prospects of using similar types of fertilizers have been analyzed. Agrochemical and microbiological analysis was carried out in specialized laboratories for organic fertilizers. It has been established that the peculiarities of animal maintenance and feeding have affected the chemical composition of manure, it is confirmed by the data of microbiological and agrochemical analysis, in particular the level of its invasive contamination. The total number of fungi in the samples ranged from 118.8 to 193.8 thousand / g. The species composition of pathogenic fungi in manure were pathogenic species of the genus Alternaria and Fusarium by 3.2%, and the number of pathogenic species of fungi not rejuvenated manure was 66.7% (from the genus Fusarium - 9.5%, from the genus Aspergillus - 57.2%). Among saprotrophic fungi there are species from the genus Penicillium (Penicillium janczewskii Zaleski, P. raciborskii Zaleski, P. simplicissimum (Oudem.) Thom, P. chryzogenum Thom) from the genus Acremonium (Acremonium Kiliense Grutz). In the first sample (fermented) the number of saprotrophic fungi from the genus Penicillium was 87.1%, from the genus Acremonium 6.5%. In the second sample (without fermentation), the number of saprotrophic fungi of the genus Penicillium decreased to 33.3%. Saprotrophic fungi of the genus Acremonium were not observed. Among toxin-forming species, Penicillium janczewskii Zaleski, Penicillium chryzogenum Thom, Aspergillus flavus, Alternaria alternata (Fr.) Keissl. and Fusarium oxysporum (Schlecht.) Snyd. et Hans) were observed. A high amount of toxin-forming fungi was found in undiluted manure - 85.7%. In the updated material, the percentage of toxin-forming fungi was lower by 16.1%. Organic fertilizer Efluent was characterized by an alkaline reaction (pH 8.5), high moisture content (98.4%), significant content of nitrate nitrogen (18.2 mg/kg), copper (4.6 mg/kg), zinc (32 mg/kg), manganese (20 mg/kg) and iron (120 mg/kg). Therefore, the use of this fertilizer will provide plants with both macro and microelements, and its application on acidic soils will also reduce the level of soil acidity. Prospects of its use in soils with the raised acidity of a soil solution are given.

This paper presents the results of mycological studies of soils left barren for 15,6 and 3 years before and after addition of pine sawdust. Considerable differences in thc species composition of fungi communities were found related both to the type of soil (period of lying barren) and treatment. Before the treatment the soil was dominated by such species as <i>Paecilomyces lilacinus, P. marquandi, Apiospora montagnei, Pseudogumnnnoscus roseus, Penicillium janczewskii, P. jensenii</i>, while after a year following addition of sawdust by <i>Trichoderma harzinum, T. pubescens, T. virens</i> and numerous species of <i>Penicillium</i>. The presence of <i>Trichoderma</i> species, comprising over 60% of the communities after the treatment indicated the possibility of creating conditions for efficient protective action against root infection of trees by <i>Heterobasidion unnosum</i> (a cause of dangerous destruction in forests growing on post agricultural land in Poland).
