Climatic Influences on Seasonal and Spatial Differences in Soil CO2 Efflux

摘要: The efflux of C02 from the soil is characterized by large seasonal fluctuations due to changes in root and microbial respiration. Although several biotic abiotic factors influence activity (see Chap. 3), control exerted temperature, some cases moisture, usually dominant. In absence water stress, variation temperature accounts for most diurnal efflux. Where stress frequently occurs, may not be correlated with but its moisture content (Rout Gupta 1989). Thus, release appears respond or whichever limiting at time measurement (Schlentner van Cleve 1985).
