Chemical dispersion in particle size analysis of latosols
01/Aug/2011
The complete sample dispersion and maintenance of stability in the dispersed phase are fundamental for a greater accuracy in soil texture analysis. For this purpose, Na+ and Li+ compounds were tested as alternative chemical dispersants, compared to a 10 mmol L-1 NaOH solution, for the possibility of a more effective dispersion and to minimize the presence of pseudo components, basically pseudo-silt, in the particle size analysis of Oxisols. Eight samples of Oxisols from the State of Minas Gerais, selected for […]
