The objective of this study was to determine the influence of selected soil properties on the relative strength of individual oil aggregates against crushing forces. Soil aggregates were crushed between a flat surface and a flat plate connected to a pocket penetrometer. Significant relationships were found between dry-aggregate stability and the clay content, sand content, CEC and ESP of the soils studied. There was also a significant positive correlation between dry-aggregate stability and wet-aggregate stability (r=0.94**). No significant relationships were found between dry-aggregate stability and silt content, organic matter content, CaCO 3 content or pH. Stepwise multiple regression analysis indicated that clay content with ESP was a good predictor of dry-aggregate stability and accounted for 0.90 to 0.96 % of the variability in the dry-aggregate stability of the soils studied.
