A substantial parameter that links plants to the soil is microbial biomass. Measurement of the biologically-active fractions of the soil organic matter, is a good way to quantify the quality of the soil. In the study, the impact of canopy and seasonal dynamics on different forest soil microbial community composition in Mid Hills of Himachal Pradesh were investigated in the forest floor under a stand of five forest ecosystems. Soil samples were collected from the organic layer and topsoil. Microbial biomass was determined by using soil fumigation extraction method and enumeration of microbial population was done by plate count technique through serial dilution using a variety of media. The study revealed that seasonal changes have a significant effect on the quantities of microbial biomass and count found in the forest floor. According to our study, the greatest amount of microbial biomass and count in the forest floor occurred during summer season. The total microbial count (Bacteria 206.97cfu g-1, Fungi 2.22cfu g-1 and Actinomycetes 8.78cfu g-1) was found highest in Ban Oak Forest and about 1521.37 µg C g-1 registered highest soil microbial biomass under Ban Oak Forest. The microbial properties followed the trend of Ban Oak Forest > Mixed Forest > Chir Pine Forest > Agriculture Field > Bare Area. The results indicates that litter quality and seasonal dynamics associated with different environmental factors like pH, moisture and temperature are crucial in determining the relative abundance of soil microbial community found in different forest ecosystem.
