Soil aggregate stability within morphologically diverse areas

CATENA, 2015
Abstract Knowledge of spatial distribution of soil aggregate stability as an indicator of soil degradation vulnerability and its possible prediction are required for many scientific and practical environmental studies. The goal of our study was to provide a model for predicting soil aggregate stability within morphologically diverse areas, where soil

Assessing soil aggregate stability with mobile phones

2020
<p>A new methodology for the assessment of soil slaking using a mobile app named SLAKES was developed. The app uses an image recognition algorithm that measures the increasing area of soil aggregates immersed in water at regular intervals over a 10 minutes period.

Stabilizing Soil Aggregates with Phosphoric Acid

Soil Science Society of America Journal, 1976
Abstract 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.

Stability of structural aggregates of dry soil

Australian Journal of Agricultural Research, 1950
The 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.

Dry Soil‐Aggregate Stability: Energy‐Based Index

Soil Science Society of America Journal, 1982
Abstract Most methods used to estimate aggregate stability apply an unmeasured force, or a measured force without knowledge of transfer, to a single or a group of aggregates. A technique is needed to estimate aggregate stability based on quantitative transfer of energy.

Effect of aggregate stability on soil compaction

Soil and Tillage Research, 1991
Abstract 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.

Aggregate Stabilities of Some Southeastern U.S. Soils

Soil Science Society of America Journal, 1997
Abstract Soils from humid regions have traditionally been considered to have stable aggregates. Some humid southeastern U.S. soils have demonstrated poor structural stability. We hypothesized that a sensitive measure of aggregate stability of southeastern U.S.

Settling Velocity of Soil Aggregates, Aggregate Stability, and Interrill Erodibility of Ten Clay Soils

Soil Erosion, 2013
Soil aggregate stability is probably the single most important soil property governing soil erodibility. Thus, soil physical, chemical, and mineralogical properties which influence such stability must ultimately also influence the soil's erodibility.

Dry‐Soil Aggregate Stability as Influenced by Selected Soil Properties

Soil Science Society of America Journal, 1992
Abstract Dry aggregate stability is an important soil physical property for evaluating tillage and wind‐erosion research. Research in this study was aimed at developing a model for predicting soil aggregate stability as influenced by intrinsic soil properties, with particular application to wind erosion.

A whole soil stability index (WSSI) for evaluating soil aggregation

Soil and Tillage Research, 2011
Soil aggregate stability is a frequently used indicator of soil quality, but there is no standard methodology for assessing this indicator. Current methods generally measure only a portion of the soil or use either dry-sieved or wet-sieved aggregates. Our objective was to develop a whole soil stability index (WSSI) by combining data from dry aggregate ...
