Resumo: Eucalyptus patches are spreading rapidly through middle Paraíba do Sul river valley and environmental effects of this activity are still ambivalent and poorly documented (Vianna et al., 2007). This study aims to evaluate the litter production and litter storage on slopes in Eucalyptus and verify its water retention capacity, to support understanding of the hydrological responses to rainfall inputs. This study aims to evaluate the litter production and litter storage of Eucalyptus. Study site is located at a headwater basin in Sesmarias river basin covered by Eucalyptus grandis x urophyla, 3 x 2 meters spaced (1666 trees. ha-1) planted in April 2004. Litter was collected in four different positions using 0.5 quadracts to litter production measurement, and 0.25 m quadracts to litter storage measurement. Samples were dried, weighted, separated in fractions (leaves, branches, grass, roots + fine material) and had the fractions weighted. Litter fall showed an increase with decreasing rainfall, and the litter fall was higher in the divisor (10.2 Mg.ha-1) than in the slope (6.6 Mg.ha-1). Litter storage presents an increase trend, with annual accumulation of 2,2 Mg.ha-1 and it is composed largely by leafs. Water retention capacity is 235%, which is close to values that are found in the Tropical rainforest (200% - 259%).

Este trabalho tem o objetivo de avaliar a produção e o estoque de serrapilheira em encostas sob plantio de Eucalyptus e verificar sua capacidade de retenção hídrica, como suporte ao entendimento das respostas hidrológicas as entradas de chuvas. A área de estudo está localizada na bacia do rio Sesmarias, numa área coberta por Eucalyptus grandis x urophyla, com espaçamento 3 x 2 m (1666 árvores.ha-1), plantadas em abril de 2004. A serrapilheira foi coletada em quatro diferentes posições usando quadrados de 0,5m para medição de produção, e quadrados de 0,25m para medição do estoque. As amostras foram secas, pesadas, separadas em frações (folhas, galhos, gramínea e raízes + material fino), as quais também eram pesadas. A produção apresentou aumento com a diminuição das chuvas, e foi maior no divisor (10,2 Mg.ha-1) que na encosta(6,6 Mg.ha-1). O estoque de serrapilheira apresenta uma tendência de aumento, com acúmulo anual de 2,2 Mg.ha-1, e é composto principalmente por folhas. A capacidade de retenção hídrica de 235% aproxima-se dos valores encontrados em Floresta Tropical Chuvosa de Encostas (200% - 259%).Universidade Federal do Rio de Janeiro2010-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/681010.11137/2010_2_66-73Anuário do Instituto de Geociências; Vol 33, No 2 (2010); 66-73Anuário do Instituto de Geociências; Vol 33, No 2 (2010); 66-731982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6810/5407Copyright (c) 2010 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMelos, Aline Riccioni deSato, Anderson MululoCoelho Netto, Ana Luiza2017-01-23T21:51:15Zoai:www.revistas.ufrj.br:article/6810Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T21:51:15Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
