VRANOV, V., HOLK, L., ROHLK, T., REJEK, K., FORMNEK, P.: Carbon, nitrogen, C/N ratio and their stand heterogeneity in the soil of Norway spruce stands. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 413–416 This work is aimed to determine the eff ect of thinning of young spruce stands in Moravian-Silesian Beskids Mts. on concentrations and relative stand heterogeneity of C ox , N t and C/N in soil. Concen-trations of C ox and N t were signifi cantly higher in individual horizons of forest humus fl oor. The thin-ning did not infl uence signifi cantly (P > 0.05) concentrations of C ox , N t 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 heterogene-ity for individual horizons ranged from 3.1 to 61.9 % in case of C ox , from 4.9 to 55.2 % for N t and from 5.3 to 42.5 % for C/N ratio. Results of this work are useful to predict stand heterogeneity of soil biochemi-cal properties which are known to correlate with especially C ox in soil on studied plots, especially soil respiration and enzymatic activities.
