Performance of a reciprocal shaker in mechanical dispersion of soil samples for particle-size analysis

Abstract: SUMMARYThe dispersion of the samples in soil particle-size analysis is a fundamental step, which is commonly achieved with a combination of chemical agents and mechanical agitation. The purpose of this study was to evaluate the efficiency of a low-speed reciprocal shaker for the mechanical dispersion of soil samples of different textural classes. The particle size of 61 soil samples was analyzed in four replications, using the pipette method to determine the clay fraction and sieving to determine coarse, fine … Show more

“…Aparecida, Simões & Andrade (2012), stated that soil texture is based on various combinations of sand, silt and clay, being the particle size distribution of a soil sample defined by relative contents of these fractions. Corá, Fernandes, Beraldo & Marcelo (2009), concluded that stability and size of soil aggregates increase mainly with concentrations of humic and fulvic acids, as well as with an increasing in oxides and hydroxides of Fe and Al.…”
