Resumo: Veredas are wetlands typically found in the Brazilian Cerrado playing important environmental functions. The hydromorphic conditions control important processes and reactions occurring in these environments. The objective of this study was to assess the pH, redox potential (Eh), and electrolytic conductivity (EC) of water from five veredas located in the Triângulo Mineiro region, nearby Uberlândia and Uberaba, Minas Gerais State, Brazil. The pH and EC of water samples (in triplicate) collected in different positions (upper, middle and bottom) of the selected wetlands were monitored monthly from September 2014 to September 2015. Eh was monitored in an incubation experiment using soil samples from the superficial layer (0-20 cm) and subsurface layer (40-70 cm) of the middle position of two of the selected veredas. In general, pH ranged from 3.4 to 6.5 throughout the year. For EC, the values ranged from 1.0 to 67.0 µS cm-1. Most of the year, pH was between 4.2 and 5.1 and EC was around 9.0 µS cm-1. Under laboratory conditions, Eh decreased from oxidic conditions to suboxidic (reduced) conditions. There were no significant differences between the wetlands and soil layers regarding the variation of Eh.

As condições de hidromorfismo controlam importantes processos e reações que ocorrem nas veredas. Objetivou-se com este trabalho, avaliar o pH, potencial redox (Eh) e condutividade eletrolítica (CE) da água de cinco veredas localizadas na região do Triângulo Mineiro, próximas dos municípios de Uberlândia e Uberaba, MG. No período de setembro de 2014 a setembro de 2015, mensalmente, foram determinados o pH e CE de amostras de água coletadas (em triplicata) em diferentes posições (terço superior, médio e inferior) das veredas selecionadas. O Eh foi monitorado em um experimento de incubação utilizando amostras de solo da camada superficial (0-20 cm) e subsuperficial (40-70 cm) do terço médio de duas das veredas selecionadas. Em geral, durante um ano, o pH variou de 3,4 a 6,5. A CE variou de 1,0 a 67,0 µS cm-1. Na maior parte do ano, o pH esteve entre 4,2 e 5,1 e, a CE, em torno de 9,0 µS cm-1. Em condições laboratoriais, o Eh decresceu de uma região oxidada para uma região suboxidada. Não houve diferenças significativas entre as veredas e camadas de solo avaliadas quanto à variação do Eh.Universidade Federal do Ceará2019-03-22T17:37:57Z2019-03-22T17:37:57Z2018-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfNASCIMENTO, D.
