3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Soil soil Mixtures of minerals and organic matter. Organic matter includes macromolecular compounds containing high levels of carbon and nitrogen and contains living small organisms (Mostly microbes). Note. The soil can be treated in the following two states. a) undisturbed soil, over time, the formation of different characteristics of the soil layer; b) disturbed soil, usually in the arable land or excavation sampling disturbed soil, used in this standard test is disturbance soil. 3.2 Mineralization process Complete degradation of organic molecules. Note. During this process, the labeled carbon atoms (14C) are quantitatively oxidized and a corresponding amount of 14CO2 is released.
