Resumo: The aim of this study was to assess organic matter and physical-hydric attributes of an Oxisol under a clonal planting of eucalypt and an abandoned pasture in comparison to a successional forest with its soil under natural conditions at Paragominas municipality, southeast region of the state of Pará. In July 2013, soil samples were collected at the depths 0-0.15 and 0.15-0.35 m, which were used for the determination of the following attributes: organic matter content; soil bulk density; porosity, soil water retention and S index. In field, soil water infiltration tests were performed. The abandoned pasture was the system that presented the greatest contents of organic matter in the soil surface, when compared to successional forest and  eucalypt clonal plantation. None of the studied systems achieved a critical level for bulk density and S index values and all systems had water infiltration speed classified as very high. Based on these variables, the soil management with eucalypt cultivation with two years of implantation may be recommended in areas with abandoned pastures.

Em julho de 2013, amostras de solo foram coletadas às profundidades 0-0,15 e 0,15-0,35 m, as quais foram utilizadas para a determinação dos seguintes atributos: teor de matéria orgânica, densidade, porosidade, curva de retenção de água e índice S. Em campo, testes de infiltração de água no solo foram realizados. A pastagem abandonada foi o sistema que apresentou os maiores teores de matéria orgânica na superfície do solo, quando comparado à floresta sucessional e ao plantio clonal de eucalipto. Nenhum dos sistemas estudados obtiveram um nível crítico para os valores de densidade do solo e índice S e todos os sistemas apresentaram uma velocidade de infiltração básica de água classificada como muito alta. Com base em tais variáveis, o manejo do solo com cultivo de eucalipto com dois anos de implantação pode ser recomendado em áreas com pastagens abandonadas.Universidade Federal de Lavras (UFLA)2016-12-232017-08-01T20:16:08Z2017-08-01T20:16:08Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfROCHA, J.
