dc.description.abstractA field experiment was conducted to determine the effectiveness of production oily waste sludges as stabilizers of wind erodible fraction, WEF (material < 0.84 mm), of sandy loams and to determine the persistence of stabilized fractions during cultivation. The waste sludge application resulted in 5 replicated soil oil contents, 0, 1.05, 1.45, 3.0, and 7.0% (by weight). Dry aggregate size distribution, DASD, determinations were carried out twice an year for five consecutive years. The soil oil content had significant influence on the temporal changes in both WEF and DASD. The amount of WEF that was stabilized by the sludge increased with soil oil content (R2 = 0.88). Similar trends were observed for aggregates > 0.84 mm and < 34 mm. Depending on the soil oil content, the potential maximum amount of WEF stabilized into aggregates > 0.84 mm ranged from 41 to 63% (R2 = 0.93). The half-life for destabilization of the stabilized WEF was 2 yr. The re-sieving data indicated that mechanical stress enhanced fragmentation of stabilized aggregates.en_US
