Concentrations of C<sub>ox</sub> and N<sub>t</sub> were significantly higher in individual horizons of forest humus floor. The thinning did not influence significantly (P &gt; 0.05) concentrations of C<sub>ox</sub>, N<sub>t</sub> and C/N ratio in particular soil horizons, with the exception of C/N ration in E horizon. Relative stand heterogeneity of the studied soil properties was mostly higher in soil of dense forest stand. The values of relative stand heterogeneity for individual horizons ranged from 3.1 to 61.9 % in case of C<sub>ox</sub>, from 4.9 to 55.2 % for N<sub>t</sub> and from 5.3 to 42.5 % for C/N ratio. Results of this work are useful to predict stand heterogeneity of soil biochemical properties which are known to correlate with especially C<sub>ox</sub> in soil on studied plots, especially soil respiration and enzymatic activities.
