Heavy metals in the soil and castor bean plants fertilized with sewage sludge stabilized by different processes
ABSTRACT: This study evaluated the levels of heavy metals in the soil and castor bean plant after fertilization with sewage sludge (SS) subjected to different stabilization processes. The study was conducted in a Haplic Cambisol with the following treatments: control (CO), fertilization with solarized sewage sludge (SSS), composted sewage sludge (CSS), vermi composted sewage sludge (VSS), limed sewage sludge (LSS), and mineral fertilizer (MF). The experimental design included a subdivided plot scheme with fertilization being the primary factor and soil layers or leaf parts being the secondary factor. The data obtained were analyzed using analysis of variance and the Scott-Knott test with 5% significance. Fertilization with SSS, CSS, and LSS led to the highest increase in Zn in the soil, mainly in the surface layer. In the leaf tissues, Zn and Cu levels were higher with the CO and SSS treatments, whereas the Ni level was higher with SSS, CSS, VSS, and MF treatments. In general, Zn and Cu levels were higher in the leaf limb than in the petiole, whereas Ni, Pb, and Cr levels were higher in the petiole than in the leaf limb. In any case, no symptoms of toxicity in the plants and no risk of soil contamination were observed with any of the fertilization treatments.
期刊介绍:
The purpose of Ciência Rural is to publish the results of original research, note and reviews which contribute significantly to knowledge in Agricultural Sciences. Preference will be given to original articles that develop news concepts or experimental approaches and are not merely repositories of scientific data. The decison of acceptance for publication lies with the Editors and is based on the recommendations of Editorial Comission, Area Committee and/ or ad hoc reviewers. The editors and reviewers are external to the institution.
