Abstract

WASTOWSKI, Arci Dirceu; ROSA, Genesio Mario da; CHERUBIN, Maurício Roberto  and  RIGON, João Paulo Gonsiorkiewicz. Characterization of chemical elements in soil submitted to different systems use and management by energy dispersive x-ray fluorescence spectrometry (EDXRF). Quím. Nova [online]. 2010, vol.33, n.7, pp. 1449-1452. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422010000700005.

This study aimed to evaluate the chemical elements levels in soil, submitted to different management systems and use by the Energy Dispersive X-Ray Fluorescence Spectrometry - EDXRF. The systems were T1 - agro forestry (SAF), T2 - Native Field (CN), T3 - Native Forest (NM), T4 - Tillage Forest (PF); T5 - conventional tillage system (SPC) and T6 - System tillage (NT). Samples were collected at 0-10 and 10-20 cm, dried and ground for analysis in EDX-720. The soil showed no difference in the average concentrations of chemical elements analyzed in the profiles, but the systems presented different concentrations of metal elements, and T3 had the highest K, Ca and Zn at 0-10 cm and higher contents of K, Ca, Cu, Zn and Mn in the layer of 10-20 cm.

Keywords : metals in soil; chemical elements; energy dispersive X-ray fluorescence spectrometry.
