Studying the influence of the aggregate sizes on some elements of an oxisol with PIXE

Abstract

An investigation of the influence of the aggregate sizes on some elements of an oxisol is presented. Proton Induced X-ray Emission (PIXE) has been used to carry out this analysis. Aggregate sizes from <0.5 mm to 4.7 mm have been used, and results confirm that the presence of Cl and Ca was greater in the small aggregate fractions. The content of K was greater in the large aggregate fractions. Fe, Al, Si, and Ti showed small differences in their concentration as a function of the aggregate sizes. © 1993 The Williams and Wilkins.
