The work was focused on the research of soil organic matter content and quality of selected forest soils. In the theoretical part of the thesis there were described in detail terms important to understand the given topic. In the practical part soil probes were excavated and soil samples were taken from individual horizons. The probing was carried out in two stands with a different representation of trees (forest type 0P, district Hodějov, Forest Management Třeboň, ownership of the Czech Republic, right to manage Forests of the Czech Republic, etc.). In the first case, it was a vegetation of deciduous trees (vegetation 356D12), in the second one with a vegetation of coniferous trees (356E11). In the laboratory of the Department of Agroecosystems of the Faculty of Agriculture of the University of South Bohemia in České Budějovice soil samples were modified and further examined in terms of the quantity and quality of soil organic matter. A new method, proposed by the collections of authors Kopecký, Kolář, Borová-Batt (2016), was used to compare the quality of the primary soil organic matter in individual samples by determining the velocity constant of the oxidation of the primary soil organic matter. The humus content was then determined and the degree of humification was calculated. The results show that the monitored parameters differ considerably in individual soil horizons. Significant differences were also observed when comparing soils of coniferous and deciduous stands. A considerable difference can be seen, for example, in the organic carbon content at the top horizons. For example, at the Ahe horizon, the total organic carbon content was found to be 39.71 % for coniferous soil, while in the leafy soil the carbon content at the same horizon was only 7.06 %. The highest value of the velocity constant to oxidation of the primary soil organic matter, which indicates its highest quality, was recorded at the Ep horizon (9-20 cm depth) of the deciduous soil probe.
