Qualidade do percolado de solos que receberam vinhaça em diferentes doses e tempo de incubação

Abstract: Neste estudo, objetivou-se avaliar a qualidade do percolado de solos que receberam doses de vinhaça em diferentes tempos de incubação. Para isto, foram reproduzidos, em 27 colunas de PVC de 20 x 110 cm (diâmetro x altura) solos classificados como Nitossolo Háplico, Argissolo Amarelo e Espodossolo Cárbico, com horizontes, espessuras e densidades semelhantes aos do solo original. Os solos foram tratados com vinhaça em doses equivalentes a 0 (Testemunha), 350 e 700 m³ ha-1 submetidos aos tempos de incubação de 30… Show more

“…Corroborating with this study, Brito et al (2007) the behavior of vinasse doses in yellow dystrophic Argisol, in which they obtained statistical differences in the COD of the percolates in the treatments that received 350 m³ ha -1 and 700 m³ ha -1 of vinasse, obtaining concentrations in percolates of 100 and 125 mg L -1 for the respective dosages, thus evidencing COD reduction efficiencies above 81% when compared to the control (water supply) treatment. The authors also report that although the vinasse doses are low, there were periods of 30 days of rest followed by the applications of the leach layers based on the volume of the pores, generating percolated and being possible to evaluate the COD behavior in the treatments.…”

“…It was shown that cation concentrations in the leachate were less than those in the vinasse, indicating the high cation retention of soils. In a complementary study [55] the physicochemical properties of percolates in soils, which received vinasse applications of 0, 350, and 700 m 3 ha −1 for different lengths of time (30 and 60 days), were evaluated and the parameters analyzed (CRO, BRO, EC, TDS, and pH) indicated lack of environmental problems and that the risk of polluting subterranean waters was low.…”

“…Brito et al (2007) aplicaram vinhaça em três tipos de solos em taxas que variaram de 0 a 700 m 3 ha -1 e observaram uma diminuição de matéria orgânica e cátions nos lixiviados, indicando que grande parte do material orgânico e inorgânico presente na vinhaça ficou retido no solo. Resposta semelhante foi obtida por Silva et al (2012), quando estudaram a distribuição de solutos em solo argiloso incubado com vinhaça.…”
