Title A name given to the resource Soil chemical attributes in function of vinasse doses and application time = Atributos químicos de um Neossolo Regolítico distrófico em função das doses e tempos de aplicação de vinhaça Creator An entity primarily responsible for making the resource Renato Paiva de Lima, Mario Monteiro Rolim�, Mara Suyane Marques Dantas, Andréa Raquel Fernandes Carlos da Costa, Anamaria de Sousa Duarte, Anderson Rodrigo da Silva Description An account of the resource The vinasse, generated from alcohol distillation, is an organic matter and nutrients rich residue widely used for fertigation in sugarcane plantings. However, if such effluent is applied in excessively high doses, it can unbalance the soil sorption complex, causing serious risks to the environment if disposed indiscriminately on soil. Thus, the objective of this study was to evaluate the effect of increasing doses of vinasse (0; 59; 119; 237e 474 m3 ha-1) and different incubation times (30 and 60 days) in the soil chemical proprieties. During the study, characterization of soil chemical attributes based on electrical conductivity of soil saturation extract (CEes), pH and exchangeable cations (K+ and Na+) levels. At the end of the study, it was concluded that the incubation time of vinasse in the soil affected the variables was studied. The contents of K+ and Na+ in the soil were significantly influenced by the application of vinasse increasing doses, however pH and CEes were little affected independent of the utilized doses. Application of water depths caused greater leaching of K+ in the soil than Na+ , which can cause sodicity of soil due to the application of high doses of vinasse. = A vinhaça é um resíduo proveniente do processo de destilação do álcool, rico em matéria orgânica e nutrientes e, por isso, é muito utilizado para fertirrigação nos próprios canaviais. Entretanto, se aplicado em doses excessivamente altas pode desequilibrar o complexo sortivo do solo e, se descartado indiscriminadamente no solo, pode trazer sérios riscos ao ambiente. Objetivou-se avaliar o efeito de doses crescentes de vinhaça (0; 59; 119; 237 e 474 m3 ha-1) e diferentes tempos de incubação (30 e 60 dias) nos atributos químicos de um Neossolo Regolítico distrófico. Durante o estudo, foram avaliadas as seguintes variáveis: condutividade elétrica do extrato de saturação do solo (CEes), pH e teores de K+ e Na+ trocáveis do solo. Ao final do estudo, foi possível concluir que os tempos de incubação de vinhaça no solo só afetaram significativamente as variáveis estudadas quando foi utilizada a maior dose de tal resíduo. Os teores de K+ e Na+ presentes no solo foram influenciados significativamente em decorrência da aplicação das doses crescentes de vinhaça, entretanto o pH e a CEes foram pouco afetados independente das doses utilizadas deste resíduo. A aplicação das lâminas de lixiviação provocou maior lixiviação de K+ do que Na+ do solo, fato que pode ocasionar a sodicidade do solo em função da aplicação de altas doses de vinhaça.
