- Abstract
The contribution of fungi and bacteria to the process of net ammonification in the soddy–podzolic soil of the wood sorrel–bilberry birch forest of Yaroslavl oblast has been determined using inhibitory analysis. Representatives of the genera Penicillium Link (70–99%) and Trichoderma Pers. (6–20%) dominate in the mycobiota of saprotrophic fungi. Seasonal changes in the total number of fungi and the content of Corg and Norg in the soil correlate only in the eluvial horizon, with r = (–0.8) and (–0.7). In horizons A0 and A2, total fungal abundance is negatively correlated with nitrogen accumulation, with r = (–0.85) to (–0.89). It has been established that the litter is characterized by an equal participation of fungi and bacteria in this process. In the humus horizon, a slight excess of the participation of fungi over bacteria is noted. In the eluvial part of the profile, the contribution of bacteria is slightly higher than the contribution of fungi. The maximum air temperature is able to regulate the seasonal dynamics of the number of saprotrophic fungi in the soil.
