Soil organic matter turnover is continuous, occurring at at annual rate of 2-4%.
Organic residues within the particulate organic carbon fraction provide a labile source of carbon for soil organisms to consume.

In gravel soil, the carbon pool is concentrated compared to a soil without gravel.
How much organic carbon could the soil store? The carbon sequestration potential of Australian soil
Journal article
Soil is a huge carbon (C) reservoir, but where and how much extra C can be stored is unknown.
Assessment of the potential for soil carbon sequestration based on soil type, land use, and climate scenarios is crucial for determining which agricultural regions can be used to help mitigate increasing atmospheric CO2 concentrations.
