Resumo: http://dx.doi.org/10.5902/198050987564This study aimed to define the critical limits of physico-hidric attributes to areas under forest and pasture and to evaluate the intensity of compression of these uses in a Hapludalf in South Brazil. The use of soils were: Native Forest – formed for arboreal species; Pasture – five years old, constituted of Brachiaria brizantha associated with Paspalum lourai and Trifolium sp.; Eucalipto 20 - Eucalyptus saligna with 20 years old, installed under conventional tillage; Eucalipto 4,5 - Eucalyptus saligna under 2nd rotation, 4.5 years old. It was evaluated the hydraulic conductivity, macro, micro and total porosity and bulk density. The eucalyptus is a potential crop to be used in recovering degraded areas with no commercial objective. Soil compression increase bulk density and decrease macroporosity and total porosity until the layer of 0.40 m in eucalyptus for commercial use and until 0.10 m in pasture. Values based on restriction and yield of annual crops or in the least limiting water range have potential to be used as restrictive values for perennial and pasture crops.

Os usos do solo constituíram-se de: Floresta - composta por espécies arbóreas e arbustivas; Pastagem - com cinco anos de idade, constituída de braquiária brizanta (Brachiaria brizantha) consorciada com pensacola (Paspalum lourai) e trevo (Trifolium sp.); Eucalipto 20 - povoamento de Eucalyptus saligna com vinte anos de idade, sendo realizado o preparo convencional do solo para implantação do povoamento; Eucalipto 4,5 - plantio clonal de Eucalyptus saligna conduzido em 2a rotação, com 4,5 anos de idade. Foram avaliadas a condutividade hidráulica do solo saturado, a porosidade (macro, micro e total) e a densidade do solo. O eucalipto tem potencial para ser utilizado em áreas de recuperação, sem objetivo comercial. A compactação aumenta a densidade e diminui a macroporosidade e porosidade total do solo até a camada de 0,40 m em eucalipto com fins comerciais e até a camada de 0,10 m em pastagem. Valores baseados em restrições ao crescimento e rendimento de culturas anuais ou no intervalo hídrico ótimo têm potencial para serem utilizados para culturas perenes e pastagem.Universidade Federal de Santa Maria2012-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/756410.5902/198050987564Ciência Florestal; Vol. 22 No. 4 (2012); 833-843Ciência Florestal; v. 22 n. 4 (2012); 833-8431980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/7564/pdfSuzuki, Luis Eduardo Akiyoshi SanchesLima, Cláudia Liane Rodrigues deReinert, Dalvan JoséReichert, José MiguelPillon, Clênio Nailtoinfo:eu-repo/semantics/openAccess2017-04-20T11:49:12Zoai:ojs.pkp.sfu.ca:article/7564Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-20T11:49:12Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
