TY - JOUR ID - 323 AU - Šír, Miloslav - Lichner, Ľubomír - Tesař, Miroslav - Krejča, Miroslav - Váchal, Jan PY - 2008 TI - Soil Water Retention and Gross Primary Productivity in the Zábrod area in the Šumava Mts. JF - Soil and Water Research IS - 1 SN - 18015395 KW - hydrologic cycle KW - evapotranspiration KW - gross primary productivity KW - entropy production KW - soil water retention N2 - The synergy between hydrologic extremes, plant transpiration, gross primary productivity, and soil water retention was studied in the experimental area Zábrod - meadow in the Šumava Mts. (Bohemian Forest) during vegetative seasons of 1983-2000. Heat balance, potential and actual transpiration, entropy production and gross primary productivity were evaluated. It was found that global radiation, precipitation amount and the soil water retention are the crucial factors determining hydrologic pattern and gross primary productivity. Insufficient soil water retention leads to small entropy production by evaporation and small gross primary productivity, which results in the extremalization of the hydrologic cycle. On the other hand, in the case of sufficient soil water retention, high entropy production by transpiration and high gross primary productivity leads to the stability of the hydrologic cycle. ER -
