Aspects of soil particle size analysis in Australia

Analysis of the particle-size characteristics of a soil can provide valuable information on the processes and products of soil formation. Studies of loess soils world-wide have used particle size as a major criterion, however, in Australia the particle-size characteristics of parna (a t y e of loess with a high clay content) have not been measured in detail. A modified method of particle-size analysis is proposed which gives more accurate results and which may contribute to a better understanding of soil formation in general, and loess formation in particular, in Australia.
