Wet sieving apparatus for disturbed samples | Royal Eijkelkamp
Description. Aggregate stability research. The wet sieving apparatus is used to determine aggregate stability. Wet aggregate stability is determined on the principle that unstable aggregates will break down more easily when immersed into water than stable aggregates. 8 sieves (with 60 mesh screen) are filled with a certain amount of soil aggregates and …

SLAKES: A Free Smartphone App to Measure Aggregate Stability
Aggregate stability is one of the most common indicators of soil health. Soils with greater aggregate stability are more resistant to wind and water erosion, and are linked to improved water capture, infiltration, and storage. The Soil Health Institute (SHI) recommends measuring aggregate stability using the Slakes app as part of a minimum ...

Aggregate Stability and Size Distribution
This chapter discusses the principles underlying the development of methods for measuring aggregate stability and size distribution. Multiple-sieve techniques give data on the amount of aggregates in each of several size groupings. To evaluate treatments or to rank soils, a single parameter to represent a soil sample is necessary.

Aggregate stability as an indicator of soil
Aggregate stability was determined by immersion in water and wet-sieving of 2-mm sieved, air-dried 0- to 10-cm soil samples, which actually tests aggregate resistance to slaking. Under simulated rainfall, runoff depth and soil loss after 30 min were negatively correlated with topsoil content in stable macroaggregates (>0.2 mm).
