27  Working out the modelled soil organic carbon stock in each layer of each stratum
            (1)    The modelled soil organic carbon stock  for each stratum h in the CEA, for 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 mass of oven dry whole soil in the stratum estimated by a modelled carbon stock estimate for the estimation event in accordance with any requirements in the Supplement () for the layer (0-30 cm or 0-x cm), in tonnes of oven dry whole soil per hectare; and
(b)  the equivalent soil mass (the ESM) defined for the CEA in the first estimation event given by section 13 of this Schedule, in tonnes of oven dry whole soil per hectare.
 (2) If , Mod is given by the following equation:
  equation 88

  where:
   is the number of sub-layers in the 0-30 cm or 0-x cm layers and used to derive (in accordance with the requirements in the Supplement).
   is the identifier for a soil sub-layer within the 0-30 cm or 0-x cm layers.
   is the mean modelled soil organic carbon stock in a soil sub-layer, for stratum h, determined by a modelled carbon stock estimate for the estimation event in accordance with the requirements in the Supplement, in tonnes of soil organic carbon per hectare.
 (3) If ,  is given by the following equation:
                 equation 89

  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 layers.
   is the modelled soil organic carbon stock in a soil sub-layer, for stratum h, determined by a modelled carbon stock estimate for the estimation event in accordance with the requirements in the Supplement, in tonnes of soil organic carbon per hectare.
   is the sum of modelled soil organic carbon stocks in all sub-layers excluding sub-layer n, for stratum h, 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 modelled soil organic carbon stock in the soil sub-layer n, for stratum h, determined by a modelled carbon stock estimate for the estimation event in accordance with any
