# Commission Decision of 10 June 2010 on guidelines for the calculation of land carbon stocks for the purpose of Annex V to Directive 2009/28/EC (notified under document C(2010) 3751) (2010/335/EU), Division 4.1: Mineral soils

Extent: E+W+S+N.I.

For the calculation of SOC the following rule may be used:
SOC = SOCST × FLU × FMG × FI
where:
SOC soil organic carbon (measured as mass of carbon per hectare);
SOCST standard soil organic carbon in the 0-30 centimetre topsoil layer (measured as mass of carbon per hectare);
FLU land use factor reflecting the difference in soil organic carbon associated with the type of land use compared to the standard soil organic carbon;
FMG management factor reflecting the difference in soil organic carbon associated with the principle management practice compared to the standard soil organic carbon;
FI input factor reflecting the difference in soil organic carbon associated with different levels of carbon input to soil compared to the standard soil organic carbon.
For SOCST the appropriate values presented in point 6 shall apply.
For FLU , FMG and FI the appropriate values presented in point 7 shall apply.
As an alternative to using the above rule, other appropriate methods, including measurements, may be used to determine SOC. As far as such methods are not based on measurements, they shall take into account climate, soil type, land cover, land management and inputs.
