Description
| - A hypothesis was verified that forest floor chemistry varies according to position within the windthrow (mound, pit, or control). A parallel assessment was made of differences in the chemistry of horizons and their forms. A total numer of 1720 windthrows were studied in the fir-beech primeval forest in the flysch zone of the Western Carpathians. A total of 100 samples were taken on three positions from the following horizons and their fOlTI1s (in brackets): litter, fermented (amphigenous, zoogenous, or mycogenous), humification (unresolved, zoogenous, residues, or humic), and mineral. A random sampling eliminated the effect of correlation between the horizons and positions. Parameters assessed were Q4/6, HAIFA, C-forms, total N, P, K, and Mg contents, soil reaction, and cation-exchange capacity. The positions exhibited a significant difference in the forest floor chemistry even at a level of horizon forms. The position's significance decreased with the horizon depth.

- Ověřována byla hypotéza, že se chemismus nadložního humusu liší podle pozice ve vývratu. Zároveň byly hodnoceny rozdíly v chemismu horizontů nadložního humusu a jejich forem. V jedlobukovém pralese Razula ve flyšovém pásmu Západních Karpat bylo studováno celkem 1720 vývratů. Na 3 mikrostanovištích – kupa, deprese, kontrola – bylo odebráno celkem 100 vzorků z těchto horizontů a jejich forem (v závorce): opadanka, fermentační (amfigennní, zoogenní, mykogenní), humifikační (nerozlišený, zoogenní, reziduální, humózní), minerální. Při odběru byl aplikován náhodný výběr s odstraněním efektu autokorelace mezi horizonty i mikrostanovišti. Hodnocena byla kvalita humusu (Q4/6, HA/FA), formy C, celkové obsahy N, P, K, Mg, půdní reakce a kationtová výměnná kapacita. Mezi mikrostanovišti byl signifikantní rozdíl v chemismu nadložního humusu, a to i na úrovni forem horizontů. Význam mikrostanoviště klesal s hloubkou horizontu. (cs)
