| Description
| - Trávy a keříky tvoří velké procento biomasy v chřadnoucích smrkových porostech a mohou silně ovlivňovat půdní organickou hmotu. Organická hmota Oa půdního horizontu z lokality v Krkonoších byla frakcionována na humusové kyseliny (HA) a fulvokyseliny (FA) a byla zjišťována závislost jejího složení na dominantách přízemní vegetace Vaccinium myrtillus, Deschampsia flexuosa a Molinia caerulea. Větší množství organického C bylo nalezeno pod porosty M. caerulea ve srovnání s Vaccinium myrtillus, ale míra humifikace byla u všech dominant obdobná. Vyšší podíl HA byl zjištěn pod porosty M. caerulea. Z toho vyplývá, že dominanty porostu mohou ovlivňovat kvalitu humusu, ale nemají vliv na kvantitativní aspekty humifikačního procesu. Vzhledem k významu HA a FA v půdotvorném procesu lze z výsledků usuzovat, že v průběhu procesu chřadnutí lesa může docházet k významným změnám nejen v humusových horizontech, ale v celém půdním profilu.

- Grasses and shrubs constitute a high proportion of the total biomass in declining forest stands and may deeply affect soil organic matter. We fractionated the organic matter of Oa horizons from the Krkonose Mts. into humic and fulvic acids (HA and FA) and related the differences to the dominant ground vegetation Vaccinium myrtillus, Deschampsia flexuosa and Molinia caerulea. Organic C was higher under M. caerulea than under Vaccinium myrtillus, but the humification rate was similar at all sites. A higher proportion of HA was found under M. caerulea, indicating that differences in species lead to variations in the quality of humic substances, but not in the quantitative aspects of the humification process. Regarding the importance of HA and FA in soil development, the findings suggest that, upon forest decline, major changes may be expected not only in the 0 horizons, but also in the whole soil profile.
