VLIV JEDLE OBROVSKÉ (Abies grandis) NA HUMUSOVÉ FORMY

Original language description

Presentation summarizes the effects of the Giant Fir stand on the humus form status: accumulation of the surface holorganic layers and their pedochemistry comparing to the Norway spruce. Quantitative sampling of the holorganic horizons was performed (frame 25x25 cm in four replications) and basic pedochemical analyses were done: pH, adsorption complex characteristics by Kappen, exchangeable acidity, total nitrogen, humus, total macroelement (N, P, K, Ca, Mg) contents and plant available macroelement contents. Giant fir represents an intensively growing introduced tree species with production of relatively favourable litter and intense uptake of nurients. This is reflected in the lower surface humus accumulation (16.528 t/ha against 28.636 in the sprucestand), its less acidity and higher bases content. On the contrary, fir uptake of limited bioelements (especially N and P) decreased their content in the forest soil. High attention to the biocycles management has to be adopted on compar
