29  Working out the modelled soil organic carbon stock for each model-validation site
        (1) The modelled soil organic carbon stock  for each model-validation site i in the CEA, within the 0-30 cm and 0-x cm layers, in tonnes of organic carbon per hectare, must be worked out under the subsection (2) or (3) based on the relationship between:
 (a) the modelled mass of oven dry whole soil () estimated by a modelled carbon stock estimate for the estimation event, for a model-validation site i, in the layer (0-30 cm or 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 (ESM) defined for the CEA where the soil samples were collected in the baseline sample round given by section 13 of this Schedule, in tonnes of oven dry whole soil per hectare.
 (2) If ,  is given by the following equation:
  equation 91

  where:
   is the number of sub-layers in the 0-30 cm or 0-x cm layer 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 91 as required by the Supplement.
   is the identifier for a soil sub-layer within the 0-30 cm or 0-x cm layer.
   is an identifier for each model-validation site collected from the stratum .

        is the modelled soil organic carbon stock in a soil sub-layer for model-validation site i, determined by a modelled carbon stock estimate for the estimation event in accordance with any requirements in the Supplement, in tonnes of soil organic carbon per hectare.
 (3) If  ,  is given by the following equation:
  equation 92

  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 13 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 layer.
   is an identifier for each model-validation site collected from the stratum .
   is the modelled soil organic carbon stock in a soil sub-layer for model-validation site i determined by a modelled carbon stock estimate for the estimation event, in accordance with any requirements in the Supplement, in tonnes of soil organic carbon per hectare.
   is the sum of
