Converts area, sampling depth, bulk density and initial/final organic-carbon mass fraction
Converts area, sampling depth, bulk density and initial/final organic-carbon mass fractions into stock estimates and a gross CO2-equivalent difference. This is a simple stock-difference calculation; it does not establish additionality, permanence, leakage, sampling representativeness, credit eligibility or verified carbon removal.
