Carbon, nitrogen, C/N ratio and their stand heterogeneity in soil of Norway spruce stands

Popis výsledku v původním jazyce

This work was aimed to determine the effect of thinning of young spruce stands in Moravian-Silesian Beskids Mts. on concentrations and relative stand heterogeneity of Cox, Nt and C/N in soil. The experiments were performed on 23-year-old Norway spruce stand located at 908 meters a.s.l. (N 49°30'10", E 18°32'20"), on plots differing in stand density. The study was restricted on horizons Oi-Oa-Oe-A-E-Bhs-Bs of Typic Haplohumod. The thinning did not influenced significantly (P>0.05) concentrations of Cox,Nt and C/N ratio in particular soil horizons, with exception of C/N ratio in E horizon. Relative stand heterogeneity of the studied properties was mostly higher in soil of dense forest stand. The reason may be higher heterogeneity of root systems and leaching of organic compounds into mineral soil connected with different intensity of throughfall. Further research is necessary to better understand these soil processes (nitrogen-carbon-soil).
