An approach for estimating fixed depth SOC stocks from horizon data is presented. Trapezoidal approach is likely to provide cruder estimates than spline method. Horizon and soil group had a significant effect on SOC stocks in both methods. SOC stock differences by soil group were mainly evident in the upper 30 cm. Demonstrated approach aims to facilitate horizon sampling use in SOC stock studies.
