"Carbon decomposition" refers to the breaking down or decay of carbon-containing substances such as plants, animals, or organic matter. Full definition
They also accounted for the rate of soil carbon decomposition as a function of temperature at the freeze - thaw boundary, which sinks deeper and deeper as soil warms. (newscenter.lbl.gov)
The results suggest that soil respiration and organic carbon decomposition in the tundra, especially in grassy areas, will increase with warming temperatures and rising soil moisture, resulting in increased carbon dioxide emissions to the atmosphere. (sciencedaily.com)
An organic carbon decomposition model, calibrated with laboratory incubations, indicates a greater production rate of CO2 - C equivalents from waterlogged (compared to drained) permafrost soils, when the higher global warming potential of methane is factored in. (nature.com)
