Soil evaporation and organic matter turnover in the Sub-Taiga and Forest-Steppe of southwest Siberia.

摘要: Southwest Siberia encompasses the forest-steppe and sub-taiga climatic zones has historically been utilized for agriculture. Coinciding with predicted changes in climate region is pressure of agricultural development; however, a characterization soil water carbon dynamics lacking. We assessed current properties organic turnover forests grasslands two sites that span forest steppe bioclimatic zones. Soil evaporation was 0.62 ± 0.17 mm d−1 (mean ± standard error) 0.45 ± 0.08 mm site. Evaporation at site 1.80 ± 1.70 mm 0.96 ± 0.05 mm plots. significantly greater than The density fine roots explained isotopic patterns between vegetation types sites. found matter to be three times faster Our results show while factors, particular snow levels, are drivers cycles, level hydrology, characteristics, directly interact influence dynamics.
