Water erosion is one of the main environmental impacts land use. When soil and water losses occur, nutrients essential for growth maintenance plants are removed, with harmful outcomes on sustainability agriculture environment. In addition, they lead to other deleterious effects, such as sedimentation eutrophication bodies. Estimation due in sub-basins prediction degradation, especially areas semi-intensive cultivation, coffee fields. Thus, aim this study was estimate relation limit loss...

RESUMO Em estado natural, os Latossolos apresentam grande estabilidade e resistência à erosão, sendo mais abundantes utilizados para atividades agropecuárias no sul de Minas Gerais. Contudo, nos últimos cem anos, estes foram submetidos a cultivos manejos que favorecem erosão hídrica.
