However, for reasons which are not well understood, many peatland soils produce smaller amounts of CH 4 than theoretically predicted, and carbon dioxide (CO 2 ) produced during anaerobic decomposition in peatland soils cannot be accounted for by commonly measured microbial processes.

Abstract Soil respiration—the flow of biologically‐generated CO 2 from the soil surface to the atmosphere—is a major component of global carbon cycling, but the long‐term response of this flux to altered precipitation regimes remains uncertain, due to different responses of soil respiration in distinct ecosystems with varying degrees of water limitation.

The dynamics of deep soil carbon are poorly understood, particularly in alkaline soils. Deep soil inorganic carbon is often overlooked in carbon accounting frameworks, leading to systematic underestimation of agricultural carbon sequestration.
