Jun 28, 2005. Soils play a key role in the global cycling of carbon. (C), storing organic C, and releasing CO2 to the atmosphere. Although a large number of studies have focused on the CO2 flux at the soil–air inter- face, relatively few studies have examined the rates of CO2 production in individual layers of a soil profile.

Mar 9, 2015. When soil scientists studies soil, they examine the soil profile. A soil profile is the vertical arrangement of different layers of soil – known as soil horizons. Soil horizons can give us a lot of valuable information by providing evidence for different geological, hydrological, biological and climate-related process.
