The depth distribution of soil organic carbon in relation to land use and management and the potential of carbon sequestration in subsoil horizons
K Lorenz, R Lal - Advances in agronomy, 2005 - Elsevier
Routine soil surveys for estimating the soil organic carbon (SOC) pool account for a soil
depth of about 1 m. Deeper soil horizons, however, may have a high capacity to sequester …

Agricultural soils as a sink to mitigate CO2 emissions
Agricultural soils, having been depleted of much of their native carbon stocks, have a
significant CO2 sink capacity. Global estimates of this sink capacity are in the order of 20‐30 …
