Fig. 2 Variation between initial and final dry mean-weight diameters (MWD) with different rates of sludge application in (A) silty clay soil, (B) loamy soil, and (C) sandy loam soil. Each value of MWD in these figures is the mean MWD for each application rate and therefore represents an average of three replicates. (24-C = composted de-inked sludge at 24 dry t ha^-1). The vertical bar represents the least significant difference (LSD) for treatments comparison at P 0.10. Treatments marked by other letters are significantly different
