Wet Aggregate Stability of Some Botswana Soil Profiles

Arid Land Research and Management, 2006
ABSTRACT 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 ...

Structure and stability of soil aggregates

Eurasian Soil Science, 2007
The 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.

Soil Aggregates — Formation and Stability

1990
The 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 ...

Microorganisms and Soil Aggregate Stability

1985
A 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

Aggregation and Aggregate Stability in Forest and Range Soils

Soil Science Society of America Journal, 1988
Abstract 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 ...

Studies on aggregate stability. I. Re‐formation of soil aggregates

Journal of Soil Science, 1986
SUMMARY When natural soil aggregates were destroyed by crushing, techniques traditionally used for re‐forming aggregates, such as wetting/drying and freezing/thawing cycles, did not produce any stable re‐formed aggregates. Incubation without amendment, was similarly unsuccessful, whereas incubation with glucose amendment did produce ...

Aggregate stability kit for soil quality assessments

CATENA, 2001
Abstract Aggregate stability affects soil strength and, therefore, the soil's ability to transmit liquids and gases, which are important functions for crop production and ecosystem health. Because aggregate stability is an indicator of vital soil functions, it can be used to assess soil quality.

Soil Aggregate Stability: A Review

Journal of Sustainable Agriculture, 1999
ABSTRACT Soil aggregate stability is a crucial soil property affecting soil sustainability and crop production. A broad outline of the processes and agents of aggregate formation and aggregate stabilization are presented and discussed in this review. Aggregate stability is difficult to quantify and interpret.

Organic Materials Which Stabilize Natural Soil Aggregates

Soil Science Society of America Journal, 1962
Abstract The effect of periodate followed by sodium borate treatment on the stabilities of prewet soil aggregates has been determined by a permeability technique and by wetsieving. The effect of periodate treatment depends on the history of the site, the depth, and the great soil group from which the sample is ...
