Abstract:
The objective was to identify stable and unstable soils and the effect of exchangeable sodium percentage (ESP) thereon, using the microaggregate stability test. Six predominantly kaolinitic and illitic soils from South Africa were used in this study. Two-gram samples of microaggregates (<105 μm) were subjected to a range of ultrasonic energy levels and particle size distribution was determined by a light-scattering technique. According to the distribution of the undispersed clay percentages with respect to energy level, the six soils were divided into unstable, semistable, and stable soils. Samples with ESP = 1 behaved like the stable soils and samples with ESP > 1 behaved like unstable soils. Microaggregate stability depended strongly on the soil clay mineralogy. -from Authors
