Fig. 6. Mean and standard deviations (bars) of soil water characteristic curves for different treatments (FGD, flue gas desulfurization by-products; FGDC, flue gas desulfurization by-products + yard waste compost; BTS, borrowed topsoil + lime; SP, unreclaimed spoil; UMS, unmined soil) for the 0- to 10-cm depth. SWC = soil water characteristic curve.
