Australian Journal of Soil Research, 1991
An Alfisol, a Mollisol and an Oxisol were fractionated into different particle sizes after a range of disaggregating treatments from gentle to vigorous. The Alfisol and the Mollisol appeared to break down in steps; macroaggregates >250 µm diameter breaking down to microaggregates 20-250 µm diameter before particles <20 µm were released ...

Soil aggregates as mass fractals
Australian Journal of Soil Research, 1995Soil aggregates have a fractal mass. That is, they are porous and, as they are studied in greater detail, more pores may be observed. Mass fractals have scale-dependent bulk density. Larger objects, or soil aggregates, have a smaller bulk density. Bulk density in soil studies is sometimes assumed to be constant.

Publisher Summary This chapter discusses the factors and mechanisms governing the formation and destruction of water-stable soil aggregates. The formation and degradation of water-stable aggregates comprise a complex interrelationship of physical, biological, and chemical reactions.

Aggregation in swelling clay soils
Australian Journal of Soil Research, 1973Dry sieving, wet sieving, and aggregate bulk density measurements were used to study the mechanisms of dry aggregate formation in three swelling clay soils. These experiments showed that, for a given soil, a single probability function can be used for all dry aggregate fractions to predict their water stability and the distribution of water stable ...

Soil aggregates and water retention
2004Publisher Summary This chapter explains the way aggregate-size distributions affect soil water retention from saturation to the wilting point. It uses the van Genuchten approximation of gravimetric water retention data and describes the effects of both aggregate-size distributions and particle-size distributions (PSDs) on parameters of the van ...
