Aggregation and Aggregate Stability in Forest and Range Soils
Soil Science Society of America Journal, 1988Abstract A simple method for measuring aggregation and aggregate stability across soils of widely varying structure and texture is presented. The method uses standard techniques of particle‐size analysis to measure yield of fine particles (<26‐µm estimated spherical diam.) after three types of dispersion treatments: shaking in ...

Structure and stability of soil aggregates
Eurasian Soil Science, 2007The formation and disintegration of macroaggregates into water-stable particles in a wide range of soil water contents—from the hygroscopic moisture to the capillary saturation moisture—were analyzed. It was found that the disintegration of macroaggregates into water-stable particles follows an exponential law.

Stability of soil aggregate in loamy soils of Slovakia
Journal of Elementology, 2017Stability of soil aggregates is affected by dozens different factors and their individual effects are hardly discernable. For this reason, we investigated the structure of the top layer (to a depth 0.2 m) of loamy soils (Haplic Fluvisol, Mollic Fluvisol and Calcaric Chernozem), at three sites (Šulekovo, Trakovice and Bučany) in the north-western part ...

Microorganisms and Soil Aggregate Stability
1985A soil aggregate has been defined as “a naturally occurring cluster or group of soil particles in which the forces holding the particles together are much stronger than the forces between adjacent aggregates” (Martin et al., 1955). The terms soil structure and soil aggregation are often used synonymously, but soil aggregates are the basic units of soil

Soil Aggregates — Formation and Stability
1990The first requirement for the efficient production of most agricultural crops is that sufficient water derived from rainfall or irrigation is accepted by the soil. Otherwise, water is not only wasted, but erosion may result. The second requirement for crops other than rice is that waterlogging does not occur, and that soil aggregates at field capacity ...

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.

The role of microorganisms in the stabilization of soil aggregates
Soil Biology and Biochemistry, 1971Abstract The maintenance of water-stability of soil aggregates bound by different chemicalbinding agents produced in situ by pure cultures of microorganisms and by an indigenous soil microflora was assessed by wet-sieve analysis. Seven fungi, six streptomycetes, and five bacteria produced binding materials in artificial aggregates of Miami silt ...

Soil colloids affect the aggregation and stability of biochar colloids
Science of The Total Environment, 2021The stability of biochar colloids plays an important role in the transport and fate of contaminants and nutrients in soil. This study aimed to investigate the effects of main soil components, kaolin (Kao), goethite (Goe), and humic acid (HA) colloids on the aggregation kinetics of biochar colloids derived from dairy manure (DM), sewage sludge (SS), and
