| Resumo: |
Swine wastewater (SW) has characteristics that allow its disposal in the soil as a fertilizer. This is an alternative in order not to accumulate this material in the farm as well as it provides savings with mineral fertilizers. The aim of this study was to evaluate the effect of applying swine wastewater on the chemical properties of a distrophic Red Latosol for two seasons. The experiment was carried out under field conditions with treatments defined as T0 = 0 (control), T1 = 150, T2 = 300, T3 = 450, T4 = 600, T5 = 750 m3 ha-1 of SW applied during the crop cycle of elephant grass. SW application contributed to the increase of magnesium and phosphorus and the reduction of soil aluminum in the first season. As for the second season when compared to the first one, there were reductions in K, Ca, and P concentrations. Hence applications of SW did not contribute to the increase in concentration of elements in the soil.
