Resumo: Soil and water losses caused by water erosion represent a risk of environmental damage and loss of soil productivity, with economic, social and environmental consequences. Plant cover is an important ally against water erosion, together with the knowledge of rainfall characteristics. Thus, this study aimed to evaluate the soil and water losses and to determine rainfall patterns in two homogeneous eucalyptus plantations; one in Yellow Argisol, located in Teixeira de Freitas, and another in Humiluvic Spodosol, located in Caravelas, both in the Extreme South of the state of Bahia. Erosion plots were installed, and consisted of three treatments: bare soil, eucalyptus, and native forest. Rainfall data was obtained from an automatic gauging station, with 10 minute registration interval for erosivity (erosivity index EI30) and rainfall pattern analyses. Higher soil losses were observed in Yellow Argisol, and the advanced rainfall pattern was predominant. Eucalyptus minimum tillage was efficient in reducing soil and water losses by water erosion.

A cobertura vegetal é um importante aliado no combate à erosão hídrica, assim como o conhecimento das características da chuva. Deste modo, o presente estudo teve como objetivo avaliar as perdas de solo e água e determinar os padrões de chuva em floresta homogênea de eucalipto em Argissolo Amarelo, no município de Teixeira de Freitas, e em Espodossolo Humilúvico, no município de Caravelas, ambas no Extremo Sul da Bahia. Parcelas de perdas de solo foram instaladas envolvendo três tratamentos: solo descoberto, Eucalipto e Mata nativa (área em equilíbrio), em ambas as classes de solo avaliadas. Para a erosividade, obtida pelo índice de erosividade em 30 minutos (EI30), e para os padrões de chuva dos eventos erosivos foram considerados dados pluviométricos obtidos em estação climatológica automatizada, com intervalos de registro de 10 minutos. As maiores perdas de solo foram observadas no Argissolo Amarelo e o padrão de chuva predominante foi o avançado. O cultivo mínimo de eucalipto mostrou-se eficiente na redução das perdas de solo e de água por erosão hídrica.Universidade Estadual de Londrina2019-02-15T09:33:16Z2019-02-15T09:33:16Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfGUIMARÃES, D.
