Výchovné zásahy a stav humusových forem ve smrkovém porostu vyšších poloh

Popis výsledku v původním jazyce

Accumulation and chemistry of the surface humus (humus forms) were studied on the Polom locality in the Orlické hory Mts. The plot was established in 1980 in 15 years old Norway spruce plantation. The density effect was studied (control variant and heavylow thinning) on the accumulation, soil reaction (pH), soil adsorption complex by Kappen, content of total carbon and nitrogen as well as content of macronutrients in the plant available (citric acid) and total forms. Differences in the humus forms werenot significant in many aspects. In the surface humus, differences in its accumulation reached 30 %, caused also by methodical problems. Differences in the soil reaction were minor, it was documented an acidification process of forest soils in the period 1993 ? 2002 on the other side. In the poor forests soils, there were not observed the changes in the soil adsorption complex and in the nutrient contents. Contents of the total nitrogen and carbon and their dynamics indicate the increas
