  1. ME, MA, MI, and SC represent soil aggregate fractions with grain sizes of > 1 mm, 0.25–1 mm, 0.053–0.25 mm, and < 0.053 mm, respectively. MWD, GMD, MWSSA, and D represent the mean weight diameter, geometric mean diameter, mean weight specific surface area, and fractal dimension of soil aggregates, respectively. Differences in homogeneous data were performed in SPSS Ver. 20.0 using one-way ANOVA with Duncan's multiple range test (P< 0.05) for means separation
