Key words: C/N ratio, ecosystem, Świętokrzyskie Mountains, organic matter
The research was led in the catchment of Base Station the Integrated Environment Monitoring of Św. Krzyż which is located on the northern slope of Łysa Góra, in the central part of the Świętokrzyskie Mountains, in the fir-beech forest ecosystem.
The samples were taken from the humus level form of rusty podzolic pseudogley soil. According to the methodology proposed by Kowalkowski and at authors (2002), the central points were species of trees which are characteristic for the typical forest ecosystem. The samples were taken from the depth 0–10 cm, along the lines led in 8 world directions. The Tree was the cardinal points, where the lines crossed. The distance of measurement points along the line amount to 10, 50, 100 and 300 cm from the tree trunk.
On Św. Krzyż the widest ratio C/N in the upper soils (0–10 cm) appears by the trees trunk and the places where is high contents of the organic matter. Data shows that the widest C/N ratio occurs by of fir trunk 25, 6:1, in the distance 50 cm 17,1:1 and on the 300 cm 19, 1:1, which indicates the slower mineralization of nitrogen.
