Abstract
A standardized ultrasonic dispersion is presented with reference to soil structure. It is suggested that the parameters of aggregate stability can be expressed by the input of ultrasound energy which causes a soil‐dependent process of aggregate dispersion. Preliminary results for soils of different land use and parent materials show that, for the soils examined, the stability of mesoaggregates (60–2,000 μm) lowers in the sequence forest > grassland > wasteland >arable land and limestone > basalt > loess > glacial till. Close correlations were also found to the content of carbon and clay.
