The soil microbiota of a grassy ecosystem in the subalpine belt of the Rila Mountain National Park showed greater amounts of fungal biomass. This remained relatively constant throughout the months of sampling while bacterial biomass was a dynamic value fluctuating within a wide range. The two groups of microorganisms also differed in their in-depth distribution in the soil profile: the bacterial biomass was relatively homogeneously distributed while the fungal biomass gradually decreased with depth. Good correlation between the amount of biomass and the values of some abiotic factors of the environment was shown by correlation analysis in a "warm" period of investigation; no distinct correlation between microbial biomass and environmental factors was observed in a "cold" period.
里拉山国家公园亚高山带一个草地生态系统的土壤微生物群显示出更多的真菌生物量。在整个采样月份中，真菌生物量保持相对稳定，而细菌生物量是一个动态值，在很宽的范围内波动。这两类微生物在土壤剖面中的深度分布也有所不同：细菌生物量分布相对均匀，而真菌生物量随深度逐渐减少。在调查的“温暖”时期，通过相关性分析表明生物量与环境中一些非生物因子的值之间存在良好的相关性；在“寒冷”时期，未观察到微生物生物量与环境因子之间有明显的相关性。
