Methods of reporting SOC stocks and statistical power
This experiment attempted to determine if there was a change in
SOC to a depth of 150 cm. In principle it is important to establish if
there is change at such depths as 30% of the organic carbon in the
150 cm profile was found at depths N60 cm. However as found in
meta-analyses, for example by Shi et al. (2013), we were unable to determine
a statistically significant change in SOC stock below 40 cm
