Última Performance of a reciprocal shaker in mechanical dispersion of soil samples for particle-size analysis Rev. Bras. Ciênc. Solo Dourado,Thayse Aparecida; Silva,Laura Fernanda Simões da; Marinho,Mara de Andrade. The 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 and total sand fractions. The silt content was obtained by difference. To evaluate the performance, the results of the reciprocal shaker (RSh) were compared with data of the same soil samples available in reports of the Proficiency testing for Soil Analysis...

A.N. Beretta, A.V. Silbermann, L. Paladino, D. Torres, D. Bassahun, R. Musselli, and A. García-Lamohte. 2014. Soil texture analyses by hydrometer: modifications of the Bouyoucos method. Cien. Inv. Agr. 41(2): 263-271. The Robinson pipette method (Pipette) is accurate and precise but time consuming. Bouyoucos (1936) proposed a more rapid and simpler procedure called the hydrometer method. Both analytical techniques are sedimentation procedures accepted as standard techniques for particle-size analysis. The sand, silt, and clay contents of several soil samples were determined using the Pipette method as a control and compared with the Bouyoucus, the Bouyoucos Modified (Bouyoucos_M) and the Bouyoucos Modified with gravimetric determination of the sand content...
