Abstract
For two years, the contribution of fungi and bacteria to the process of net ammonification in soddy-podzolic soil of the sorrel–blueberry birch forest of Yaroslavl oblast was determined using inhibitory analysis. It was established that the litter is characterized by equal participation of fungi and bacteria in this process. In the humus horizon, a slight excess of fungi over bacteria was noted in years of normal moisture and there was a clear dominance of fungi in dry years. In the eluvial part of the profile, the close contribution of these groups was noted, with an insignificant prevalence of one of them over the years of study. The maximum air temperature is able to change the seasonal dynamics of the abundance of saprotrophic fungi in the soil and to some extent form the generic structure of the mycobiota in the horizons of the soil profile of the birch forest.
