Table 3. Means of mineral soil carbon storage ± one standard error across all land-use types and soil depths. Reported P-values and F-values 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.
