Small-scale variation of microbial activities in a forest soil under a beech (Fagus sylvatica L.) stand
Goemoeryova, E.(Technical University, Zwolen (Slovakia). Faculty of Forestry)
The aim of this study is to investigate the small-scale (100 square m) spatial variability of selected soil biological properties in a beech stand to provide more efficient sampling and to evaluate the influence of soil properties on microbial activity. In soil samples, soil respiration and catalase activity were measured. Within plot-coefficients of variation of catalase activity varied from 19 to 23 percent, those of soil respiration rate ranged from 37 to 54 percent. Catalase activity exhibited highly significant correlations with soil reaction, whereas soil respiration rate correlated with moisture and humus content
