Wet sieving method, complete set, up to 8 samples at once (Discontinued)

The wet sieving apparatus is used to determine the aggregate stability of a soil, which is the resistance of soil structure against mechanical or physico-chemical destructive forces. Due to the impact of aggregate stability on plant growth and soil loss, applications of the wet sieving apparatus are the fields of agriculture and land conservation. This method to determine aggregate stability will be especially useful for researchers and scientists on soil erosion, land degradation and conservation, agriculture, sustainable agriculture.
Scientists on salinization problems may have advantage determining wet aggregate stability using wet sieving, to control deterioration of soil structure or to determine possible impacts of amelioration practices on aggregate stability. The wet aggregate stability is determined on the principle that unstable aggregates will break down more easily than stable aggregates when immersed into water.
To determine the stability, 8 sieves (with 60 Mesh screen) are filled with a certain amount of soil aggregates. These sieves are placed in a can filled with water, which will move up and downward for a fixed time. Unstable aggregates will fall apart and pass through the sieve and are collected in the water-filled can underneath the sieve. After this fixed time, the cans are removed and replaced by new water filled cans. Now, all aggregates are destroyed. Sand grains and plant roots will remain on the sieve and only aggregates are considered. After drying the cans with the aggregates, the weight of both stable and unstable aggregates can be determined.
