Abstract

In this work aimed to evaluate the effects of the use of wastewater from dairy cattle in the concentration of metals in a cultivated ultisol with fig (Ficus carica L.). The work was developed in the area of the Integrated Agroecological Production in the municipality of Seropédica, RJ. The nitrogen was used as a reference element in fertilization of the fig tree with application of wastewater from dairy cattle. We evaluated the following parameters of the soil Zn, Cu, Fe and Mn availables. The data were submitted to analysis of variance and means were compared using the Tukey test at 10% probability. Regarding the content of metal, it was observed that the use of wastewater of cattle in the fig tree fertilization was able to reduce the concentration of Zn elements Cu, Fe and Mn that were in high concentrations in the soil indicating toxic levels. Also noteworthy that the organic matter incorporated into the soil may have acted in thechelation and complexation, forming precipitates of low mobility of Zn, Cu, Fe and Mn.
