20.500.12556/RUL-69068 Sources of soil CO2 in calcareous grassland with woody plant encroachment Purpose The objective of this study is to estimate the contribution of various sources that influence soil CO2 concentrations in calcareous grassland. Materials and methods The research was performed at the Podgorski Kras plain (45 °33′ N, 13 °55′ E, 400–430 m.a.s.l.) in the sub-Mediterranean region of Slovenia (SW Slovenia), where many meadows and pastures have been abandoned. In parallel to the measurement of soil respiration R s, soil gas was sampled for stable isotope analysis. Samples were taken biweekly at two sites, Grassland and Invaded, from July 2008 until November 2010. In addition, daily variations in concentration and stable isotope composition of soil CO2 were determined in May 2009. The partitioning of soil CO2 concentrations was performed using stable isotope mass balance calculation. anorganski CO2 kraška travišča organski CO2 stabilni izotopi raspiracija tal pedologija true false false Angleški jezik Neznan jezik Znanstveno delo 2015-07-10 21:17:27 2015-07-10 21:17:27 2022-07-11 03:41:33 0000-00-00 00:00:00 2012 0 0 Str. 1327-1338 no. 9 Vol. 12 2012 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*1 1439-0108 3420838 http://dx.doi.org/10.1007/s11368-012-0564-3 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=69079 Biotehniška fakulteta 0 0 0
