6 Determining Equivalent Soil Mass (ESM) from sampling round masses (1) The equivalent soil mass (the in tonnes per hectare, for each CEA must be ESM), calculated in accordance with this section. (2) The corrected soil masses from equation 6 must be: Mi (a) ranked from lowest to highest for each CEA; and (b) assigned a sequential rank from 1 to the number of samples in the CEA k N. (3) A percentile must be calculated for each value of using the following equation: P k equation 7 (4) If one of the percentiles given by equation 7 is 10—the for the CEA is the mass of ESM the soil layer given by equation 6. (5) If subsection (4) does not for each CEA is given by the following ESM equation: equation 8 is the corrected soil mass of the sample which has been assigned the lower bound MLB i, rank as having the value of closest to and lower than 10, in tonnes of soil per LB P hectare, as given by equation 6. is the corrected soil mass of the sample has been assigned the upper bound MUB i, rank as having the value of closest to and higher than 10, in tonnes of soil per UB P hectare, as given by equation 6. is the percentile associated with the lower bound rank given by equation 7. PLB P LB is the percentile associated with the bound rank given by equation 7. PUB P UB 7 Calculation of SOC stock in each sample (1) If carbon analysis is undertaken on a homogenised sample as outlined in the Supplement—the for each sample in tonnes of carbon per hectare, is given by the i, following equation: equation 9 where: is determined in accordance with section 6 of this Schedule for the CEA to which ESM the sample belongs. is the organic carbon content of the sample layer of sample as a percentage of OCi i, oven dry soil mass, determined in accordance with any requirements in Supplement.
6 Determining Equivalent Soil Mass (ESM) from sampling round masses (1) The equivalent soil mass (the ESM), in tonnes per hectare, for each CEA must be calculated in accordance with this section. (2) The corrected soil masses Mi from equation 6 must be: (a) ranked from lowest to highest for each CEA; and (b) assigned a sequential rank k from 1 to the number of samples in the CEA N. (3) A percentile P must be calculated for each value of k using the following equation: equation 7 (4) If one of the percentiles given by equation 7 is 10—the ESM for the CEA is the mass of the soil layer given by equation 6. (5) If subsection (4) does not ESM for each CEA is given by the following equation: equation 8 MLB is the corrected soil mass of the sample i, which has been assigned the lower bound rank LB as having the value of P closest to and lower than 10, in tonnes of soil per hectare, as given by equation 6. MUB is the corrected soil mass of the sample i, has been assigned the upper bound rank UB as having the value of P closest to and higher than 10, in tonnes of soil per hectare, as given by equation 6. PLB is the percentile P associated with the lower bound rank LB given by equation 7. PUB is the percentile P associated with the bound rank UB given by equation 7. 7 Calculation of SOC stock in each sample (1) If carbon analysis is undertaken on a homogenised sample as outlined in the Supplement—the for each sample i, in tonnes of carbon per hectare, is given by the following equation: equation 9 where: ESM is determined in accordance with section 6 of this Schedule for the CEA to which the sample belongs. OCi is the organic carbon content of the sample layer of sample i, as a percentage of oven dry soil mass, determined in accordance with any requirements in Supplement.
