Soil-Aggregate Crushing-Energy Meter, A - USDA

Aggregate stability has been considered to be a func-tion of the energy required to alter a sample. Some (Mar-shall and Quirk, 1950; Grossman et al., 1959; Gill and McCreery, 1960; Farrell et al., 1967) have used a drop-shatter technique. In this method, the aggregate stability is expressed in terms of the height from which the sample
