13  Working out the soil organic carbon stock in each layer
 (1) The soil organic carbon stock  for each soil sample i within the 0-30 cm and 0-x cm layers, in tonnes of organic carbon per hectare, must be worked out under subsection (2) or (3) based on the relationship between:
 (a) the mass of oven dry whole soil collected () for the sample layer (0-30 cm and 0-x cm) worked out in accordance with any requirements in the Supplement, in tonnes of oven dry whole soil per hectare; and
 (b) the equivalent soil mass (the ESM) defined for the CEA in the baseline sampling round, given by section 12 of this Schedule, in tonnes of oven dry whole soil per hectare.
 (2) If ,  is worked out using the following equation:
  equation 52

  where:
 is the number of sub-layers in the 0-30 cm or 0-x cm layers and used to derive  (in accordance with any requirements in the Supplement).
             Note:  The value of n increases with increasing depth such that sub-layer 1 denotes the soil sub-layer including the soil surface and sub-layer n denotes the deepest sub-layer that contributes to equation 52 as required by the Supplement.
 is the identifier for a soil sub-layer within the 0-30 cm or 0-x cm layers.
 is the soil organic carbon stock in a soil sub-layer determined in accordance with any requirements in the Supplement, in tonnes of soil organic carbon per hectare.
 (3) If  ,  is worked out using the following equation:
  equation 53

  where:
 is the number of sub-layers progressing incrementally down from the soil surface required to produce a value for  that is equal to or exceeds the ESM for the CEA given by section 12 of this Schedule, in tonnes of oven dry whole soil per hectare.
Note: The value of n increases with increasing depth such that sub-layer 1 denotes the soil sub-layer including the soil surface and sub-layer  denotes the sub-layer .
 is the identifier for a soil sub-layer within the 0-30 cm or 0-x cm layers.
 is the soil organic carbon stock in a soil sub-layer determined in accordance with any requirements in the Supplement, in tonnes of soil organic carbon per hectare.
 is the sum of soil organic carbon stocks in all sub-layers excluding sub-layer n, in tonnes of soil organic carbon per hectare.
 is the soil organic carbon stock in the sub-layer n, in tonnes of soil organic carbon per hectare, determined in accordance with any requirements in the Supplement.
ESM is the equivalent soil mass for the CEA given by section 12 of this Schedule, in tonnes of oven dry whole soil per hectare.
 is the oven dry mass of whole soil within
