57. The initial quantity of the carbon stock in the soil carbon reservoir is determined using equation 7. The result of the equation must be entered into the CBM-CFS software for the simulation of the baseline scenario and project scenario.Equation 7
CSoilRef = ((Yearinv – 1990) x 0,0167 + 1) × tCsoilDP/ha
Where:
CSoilRef = Carbon stock present in the soil, in metric tonnes of carbon per hectare, at the start date of an early project;
Yearinv = Year when the inventory to determine the initial carbon stock in the soil was done;
0.0167 = Annual rate of carbon accumulation in the soil following site preparation work;
1 = Term linking the estimated carbon stock present at the start of the early project with the measured carbon stock present in the soil of the lot or part of a lot for the project;
tCsoilDP/ha = Carbon stock in the soil carbon reservoir, in metric tonnes of carbon per hectare, determined using the compiled value of the carbon stock obtained following the analysis of soil samples taken during the initial inventory of the lot or part of a lot for the project.
