Soil slaking assessment using image recognition
An aggregate is a group of primary particles that cohere to each other and their stability is a function of the binding forces between them that withstand after an applied disruptive event (Kemper and Rosenau, 1986).As reviewed by many authors e.g., (Tisdall and Oades, 1982, Kemper and Rosenau, 1986, Field et al., 1997, Amézketa, 1999, Dıaz-Zorita et al., 2002, …

A practical, reproducible laboratory method for assessing soil
2018). Aggregate stability is one of the key indicators for soil health (Rieke et al., 2022). Various methods have been developed for quantifying soil aggregate stability. Because aggregate stability is not a direct intrinsic chemical or physical measurement such as soil pH or bulk density, it is (in practice) defined by the measurement method.

Soil aggregate stability (SAS) is needed to evaluate the soil's resistance to degradation and erosion, especially in semi-arid regions. Traditional laboratory methods for assessing SAS are labor-intensive and costly, limiting timely and cost-effective monitoring. Thus, we developed cost-efficient wall-to-wall spatial prediction maps for two fundamental SAS …

Evaluation of aggregate stability methods for soil health
Aggregate stability is generally quantified as the fraction of aggregates remaining after exposure to destabilizing stressors (Angers and Carter, 2020).The measure is a valuable indicator of soil health because it is conceptually linked to soil hydrologic function (Arshad and Coen, 1992, Hortensius and Welling, 2008, Moncada et al., 2015) and empirically linked to …

Exploratory assessment of the SLAKES method to characterize aggregate
Classical soil aggregate stability (AS) methods lack standardized protocols and require long measurement times. However, the fairly new SLAKES method purportedly allows for rapid AS estimation with minimal technical equipment. SLAKES has been tested on fine-textured soils but its suitability for other soil types is unknown.

Aggregate stability as an indicator of soil susceptibility to runoff
This was done through comparisons of topsoil aggregate stability and field-assessed susceptibility to runoff and erosion. Aggregate stability was determined through immersion and subsequent wet-sieving of <2-mm air-dried soil samples into water, which actually tests aggregate resistance to slaking (Le Bissonnais, 1996).
