Resumo: | This work was carried out at Federal University of Santa Maria campus, Rio Grande do Sul, Brazil, with the objective to evaluate the influence of residues management system of an black wattle reforestation on water and soil losses from natural rainfall. The treatments were: T1 - shallow clear cutting burned; T2 - cut and deposition of the residues and T3 - reforestation of black wattle. The treatment T1 had significantly greater water losses than T2, which also had significantly greater water losses than T3. The precipitation during the studied period was 1,384 mm, with anerosivity index (EI30) of 7,474 MJ mm ha-1 h-1. The soil losses evidenced significantly differences between T1 and the other two treatments T2 and T3, which reduced the soil losses in 99,6% and 99,9%, respectively, in relation to T1. |

Este trabalho foi conduzido no Campus da Universidade Federal de Santa Maria, Rio Grande do Sul, com o objetivo de avaliar a influência do sistema de manejo dos resíduos da exploração de um reflorestamento de acácia-negra sobre as perdas de água e solo provocadas por chuva natural. Os tratamentos consistiram: T1 - corte raso e queimada dos resíduos; T2 - corte raso e deposição dos resíduos; e T3 - reflorestamento de acácia-negra. O tratamento T1 perdeu significativamente mais água que o tratamento T2, o qual também perdeu significativamente mais água que o tratamento T3. A precipitação durante o período estudado foi de 1.384 mm, com índice de erosividade de chuva (EI30) de 7.474 MJ mm ha-1 h-1. As perdas de solo evidenciaram diferenças significativas entre T1 e os outros dois tratamentos T2 e T3, os quais reduziram as perdas de solo em 99,6% e 99,9%, respectivamente, em relação a T1.Universidade Federal de Santa Maria1998-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35010.5902/19805098350Ciência Florestal; Vol. 8 No. 1 (1998); 43-53Ciência Florestal; v. 8 n. 1 (1998); 43-531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/350/221Silva, Lauro Leal daSchneider, Paulo RenatoEltz, Flávio Luiz Folettoinfo:eu-repo/semantics/openAccess2017-06-09T11:24:43Zoai:ojs.pkp.sfu.ca:article/350Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-09T11:24:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
