Abstract
Efflux of carbon dioxide from soil is a central component of the carbon cycle and climate models, but one potentially large source is rarely indicated, namely, photochemical decomposition of soil organic matter. A survey from diverse environments around the world shows that this process is almost ubiquitous and comparable in magnitude to respiration. Moreover, it can persist when respiration subsides, such as in dry and cold soils.
期刊介绍：
The scope of ACS Earth and Space Chemistry includes the application of analytical, experimental and theoretical chemistry to investigate research questions relevant to the Earth and Space. The journal encompasses the highly interdisciplinary nature of research in this area, while emphasizing chemistry and chemical research tools as the unifying theme. The journal publishes broadly in the domains of high- and low-temperature geochemistry, atmospheric chemistry, marine chemistry, planetary chemistry, astrochemistry, and analytical geochemistry. ACS Earth and Space Chemistry publishes Articles, Letters, Reviews, and Features to provide flexible formats to readily communicate all aspects of research in these fields.
