Effect of aggregate stability on soil compaction
Soil and Tillage Research, 1991Abstract Investigations of three differently textured and structured soils showed that soil compaction is a function of texture, structure, matric water potential and type and intensity of loading. Time-dependent consolidation and shear experiments revealed that fine-textured soil is more compressible than heavier soil.

Stability of structural aggregates of dry soil
Australian Journal of Agricultural Research, 1950The stability of natural aggregates of dry soil has been examined by a drop-shatter method similar to that used in coal technology, The median size was determined after dropping from heights of 30, 60, 120, and 240 cm. The dropping procedure subdivides aggregates along surfaces of weakness into smaller natural units.

Emerging threats to the stability of soil aggregates
2021Soil aggregates are clusters of soil particles, supporting the soil physical structure. Soil aggregation is key to the functions of ecosystem, including aeration, water infiltration and storage, nutrient cycling, and the pore system. This doctoral work investigates the effects of threats on the stability of soil aggregates.

The Influence of Soil Aggregate Stabilizers on the Biological Activity of Soils
Soil Science Society of America Journal, 1954Abstract The influence of three synthetic polyelectrolytes, hydrolyzed polyacrylonitrile (HPAN), modified vinyl acetate maleic acid compound (VAMA), and a new polymer 212 on the biological activity in six agricultural Arizona soils and quartz sand was investigated.

Stabilizing Soil Aggregates with Phosphoric Acid
Soil Science Society of America Journal, 1976Abstract Four P‐containing fertilizer materials (H 3 PO 4 , liquid and dry ammonium polyphosphate, and triple superphosphate) were compared for ability to increase water stability of aggregates in an acid soil.

Wet Aggregate Stability of Some Botswana Soil Profiles
Arid Land Research and Management, 2006ABSTRACT During intense and short rainfall events, important losses of fertility are expected as a result of erosion in drylands because the nutrient pools are concentrated in the topsoil. Therefore, we evaluated the kinetics of aggregate stability in some Haplargids and Torripsamments in Botswana as it represents a resistance factor against losses of ...

Soil aggregation: Formation, stabilization, and impacts of soil management
2023Soil structure has as its main component the soil aggregate, which is composed primarily of particles of sand, silt, and clay, bound together by inorganic and organic materials at various scales. However, the concepts and models explaining how soil aggregates form and stabilize have evolved over the years.
