HIGHLIGHTS

Higher concentrations of exchangeable Zn were found in areas with pig slurry application.

No higher concentrations of Cu were found in the exchangeable fraction in areas using pig slurry.

In all study areas, it was observed that more than 70% of Cu is in recalcitrant forms.

Key words:
organic fertilization; heavy metals; agro-industrial residue; Cerrado

ABSTRACT

Disposal of pig slurry in the soil as a source of nutrients to plants, if improperly performed, can contribute to the contamination of ground and surface water and plants by the elements zinc (Zn) and copper (Cu). This study aimed to evaluate the zinc and copper fractions in Oxisols of different textures submitted to successive applications of pig slurry. Soil samples were collected in areas with and without pig slurry use, in the 0 - 0.10 and 0.10 - 0.20 m layers. The available and unavailable fractions of Zn and Cu were determined by sequential chemical fractionation, and the total and available Zn and Cu concentrations were evaluated. The Kruskal-Wallis test analyzed results. The areas with the longest pig slurry use showed the highest Zn concentrations in the most available forms. The soils in areas with and without pig slurry use showed a predominance of Cu in the not available form.
