Fig. 3. Relative share of soil organic carbon (SOC) in soil by different aggregate size fractions under different land uses (bari, rainfed upland; khet, irrigated lowland; DF, degraded forest and shrub land; DS, dense Shorea forest; PS, pine–Shorea forest; SC, Schima–Castanopsis forest; SPS, Schima–pine–Shorea forest). Mean ± SE; values with different letters, uppercase for land uses and lowercase for aggregate size classes, are significantly different at P < 0.05 (Student–Newman–Kuels = 0.05).
