The dispersion of Oxisol samples can be somewhat difficult due to highly stable microaggregates that are not always completely destroyed by chemical and mechanical dispersion. It is therefore important that chemical and mechanical methods are combined, along with the pretreatment of the sample, for complete and stable soil particle dispersion throughout the analytical procedures. Thus, this study aimed to evaluate the efficiency of mechanical dispersion (slow agitation with an orbital shaker – 30 rpm for 16 h, in the presence […]
