Abstract

The objective of this study was to evaluate the chemical alterations in soil resultant from the application of different doses of tannery wastewater (ARC) on Mombasa grass (Panicum maximum cv. Mombasa). Based on the chemical composition of the wastewater the following application doses of ARC were established: T1 = 0.0; T2 = 1.5; T3 = 3.0; T4 = 5.0; T5 = 10.0 e T6 = 15.0 kg?ha-1 of chromium. According to the results obtained it was concluded that the tannery wastewater provided a reduction in the concentrations of available P and K in the soil, which was probably a result of increased absorption of these elements by plants. The total nitrogen concentrations remained virtually unchanged, while sodium increased with elevated ARC doses. Chromium, in its available form, was not detected in soil even in the larger doses applied.
