Concentração de cátions presentes no lixiviado de solos tratados com vinhaça

Abstract: O presente estudo teve como objetivo avaliar a qualidade do lixiviado de solos que receberam doses de vinhaça em diferentes tempos de incubação. Para isso, em 27 colunas de PVC de 20 x 110 cm (diâmetro x altura), foram reproduzidos três solos classificados como Nitossolo Háplico, Argissolo Amarelo e Espodossolo Cárbico, com horizontes, espessuras e densidades semelhantes à original. Os solos foram tratados com vinhaça em doses equivalentes a 0 (testemunha), 350 e 700 m³ ha-1 e submetidos aos tempos de incubaçã… Show more

“…In studies applying different doses of vinasse to soils, Bebé et al (2009), Brito et al (2007, and Canellas et al (2003) reported increased potassium concentrations in the top and deep soil layers that were proportional to the amounts applied, corroborating the results of the present study. Vinasse contributes significantly to reducing mineral fertilization requirements, and 150 m 3 ha -1…”

“…As soon as the organic matter contained in the vinasse is incorporated into the soil, it is colonized by fungi, which transform it into humus, neutralizing the acidity of the medium and thus increasing the soil pH (SILVA et al, 2007). Increases in pH in the deepest soil layers in response to vinasse applications have also been reported by Brito and Rolim (2003) and Brito et al (2007).…”

“…Dentre os metais quantificados estão presentes, em concentrações de mg/L, os elementos: ferro, manganês, estrôncio, cobre, níquel, chumbo, cromo e cobalto. A vinhaça estudada é semelhante às características obtidas por Brito et al (2007) (Ribeiro et al, 1983). : 0,85) em colunas de percolação contendo latossolo vermelho distrófico (67% areia, 7% silte e 26% argila).…”
