Description: The possibility of using peat as a solid base for a microbial preparation was investigated. The basis of the microbial consortium of the drug was made up of Pseudomonas extremorientalis and Aeromonas media isolated from coprolites of the earthworms Eisenia fetida, Savigny. Among the studied peat species, eutrophic woody peat (pH = 5.7, degree of decomposition 48%) was chosen, which stimulated the increase in the aboveground mass (+11%) of wheat seedlings in preliminary tests. We assessed the viability of bacteria within 2 months after their adsorption on peat. On the 56th day of the experiment, the number of A. media in the variant with a peat carrier remained at the highest possible level - 107 CFU / ml. In a vegetation experiment, it was found that the use of two microbial cultures (in liquid form and in solid after adsorption of bacteria on peat) for presowing seed treatment led to an increase in wheat germination by 9% (83% for the liquid form and 92% for the solid form). Plant biomass increased in variants using bacteria on peat compared to using bacteria in liquid form. The presence of peat and P. extremorientalis increased the aboveground weight of wheat by 5%, while peat with a mixture of bacteria increased this figure by 15%. In variants with the use of P. extremorientalis on peat, the rate of development of plant diseases decreased in comparison with the liquid form by more than 3 times. With the combined use of bacteria, peat provides high rates of germination of seeds and aboveground mass. The research results indicate a greater efficiency of using a solid preparative form of a microbial preparation in comparison with a liquid one.
