Table 3. Means of mineral soil carbon storage ± one standard error across all landuse types and soil depths. Reported Pvalues and Fvalues were derived from individual ANOVAs performed for each soil depth. For each analysis, the numerator degrees of freedom were 2 and denominator degrees of freedom were 43. Different superscripted letters represent significant differences among categories, as determined by means separation.
