Název v původním jazyce

Wood production, litter fall and humus accumulation in a Czech experiment in Norway spruce (Picea abies (L.) Karst.)

Popis výsledku v původním jazyce

This paper reports results from a thinning experiment in even-aged Norway spruce. The experiment includes five treatments with four (pseudo) replications in two blocks. The treatments comprise four thinning regimes and an unthinned control. The thinningregimes were defined based on two levels of simulated mechanization, two different selection principles, three different sequences of thinning operations, and two different rack widths (3.5 or 5.0 m). All treatments, except the unthinned control, includean early, heavy thinning and aim for a final crop of 400 preselected trees per ha. There were no differences between litter fall in the unthinned control and the thinned plot, but a lower content of biomass and nutrients (except calcium) in the thinnedplot. This supports the theory of faster decomposition and cycling of nutrients in organic horizons of thinned stands, as compared to unthinned stands of even-aged Norway spruce.
