| Description
| - Četné studie ukázaly, že vegetace a s ní spojená mikrobiální aktivita může ovlivňovat transport vody v půdě tím, že povleče půdní částice hydrofobním filmem, který významně mění jejich povrchové vlastnosti. Cílem této studie bylo vyhodnotit působení vegetace na transportní vlastnosti písčité půdy v lokalitě Mlaky II v Sekule (jihozápadní Slovensko). Byla zkoumána čtyři stanoviště s rozdílnými typy vegetačního krytu: (1) louka pokrytá hlavně různými druhy trávy, (2) holina porostlá hlavně mechy a lišejníky, (3) zamokřené podloží, kde byl snížený vliv vegetace a (4) borový les. Transportní vlastnosti půdy jsou určeny saturovanou hydraulickou konduktivitou Ks, nesaturovanou hydraulickou konduktivitou v hloubce -2 cm ks(-2 cm) a poměrem vodního toku póry s poloměrem r větším než přibližně 0.5 mm Br.

- The influence of plant transpiration on the entropy exchange was quantified as associated with the degradation of solar energy on the Earth’s surface covered by plants. Two surfaces were studied: (1) productive surface – plant transpiration taken as equal to the potential one, (2) non-productive surface – plant transpiration taken as equal to zero. The entropy exchanges associated with the absorption of solar radiation and with the conversion of absorbed solar radiation into the sensible heat and latent heat were taken into account. These processes were examined in the experimental watershed Liz (828–1074 m a. s. l.) located in the Bohemian Forest (Czech Republic). We found that in the growing season 1992 the net entropy exchange in humid hydrologic period (the Earth’s surface is productive) was considerably higher than in the arid one (the Earth’s surface was productive in 39% of days, and non-productive in 61% of days).
