Caracterização dos níveis de elementos químicos em solo, submetido a diferentes sistemas de uso e manejo, utilizando espectrometria de fluorescência de raios-x por energia dispersiva (EDXRF)

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