Impactos Da Aplicação De Lodo De Esgoto Na Cultura Da Cana-De-Açúcar E No Ambiente

Abstract: A pesquisa de campo teve por objetivo avaliar os efeitos da aplicação de lodo de esgoto (LE), complementado ou não com adubos NP, NK, PK e NPK, sobre a nutrição e produtividade da cultura de cana-de-açúcar, para caracterizar o potencial do lodo em fornecer nutrientes, e os possíveis impactos ambientais devido à presença de metais pesados em um Argissolo Vermelho-Amarelo distrófico. O LE foi aplicado nas doses de 0, 20 e 40 t ha 1 (material úmido, com 620 g kg-1 de água) e o N, P e K, respectivamente, nas doses… Show more

“…In industrial practice, high levels of aluminium are associated with low cell viability and reduced ethanol yield. Very low levels of cadmium were found in sugar cane from an area fertilized with treated municipal sewage sludge (Silva et al 2010). Even so, the cell recycling and the yeast capacity of cadmium accumulation led to a toxic level of this metal to yeast fermentation.…”

“…Although sewage sludge is also very lacking in K, it has high levels of P [60]. This organic fertilizer can improve soil's physical and chemical characteristics and can increase sugarcane productivity, acid phosphatase activity, and biomass [61]. These authors also highlighted the beneficial effect of B, Zn, and Cu from sewage sludge in association with available P that provided increase in the stalks production.…”

“…Para o feijão, foi encontrado resultados divergentes, variando de 14 t ha -1 de biossólido a 40 t ha -1 de composto (LOBO et al, 2012;CUNHA, 2011). Para a cultura da cana-de-açúcar, Silva et al (2010) recomendam aplicações de até 40 t ha -1 .…”
