Decomposition of organic matter in soil is influenced by abiotic and biotic factors and their role is different depending on site, organic substrate and its decomposition phase. Soil microbial community influences soil organic decomposition process in a different way, which is manifested, for example, by changes of microbial abundance and production of extracellular enzymes. The thesis aimed in determining relationship of two main soil microbial decomposers groups - fungi and actinobacteria in decomposition processes in situ. The impact of selected factors on decomposition processes were determined by experiment with litterbags, which were filled with litter of plant with different properties. Astragalus exscapus from the Fabaceae family contains high amounts of nitrogen in the tissues, Fagus sylvatica contains high amounts of carbon and lignin and Carex humilis has less carbon in the tissues than Fagus sylvatica falling in tissue element composition between Astragalus exscapus and Fagus sylvatica. Litterbags with three plant species were put under a litter layer at both contrasting sites. Litterbags and samples of soil were collected every two months during the years 2011-2012. Each litterbag was weighted, DNA was isolated from litter and soil samples and analyses of quantitative real time PCR...
