Resumo: Litter production and decomposition of an Atlantic Forest fragment in Marambaia Island, Mangaratiba, RJ, were monitored from December 2003 to November 2004. For the litter deposition evaluation, 30 litter traps were installed and 36 litter bags were allocated in the area to quantify litter decomposition. Soil samples were collected at 0-5 cm, 5-10 cm and 10-20 cm depth to evaluate soil fertility. The litter production was 7.9 Mg ha-1 and the highest deposition was verified in November and the lowest in June. The leaf fraction presented the highest contribution comparing to the others. In seven months of observation, litter decomposition rate was 40% and showed an exponential decrease. Different behavior for N, P and K release was verified. Exception for P, carbon, nutrients and H+Al presented highest concentrations in superficial layer.

A produção e a decomposição de serapilheira de um fragmento de Floresta Atlântica de encosta na Ilha da Marambaia, Mangaratiba, RJ, foram estudadas durante o período de dezembro de 2003 a novembro de 2004. O aporte de serapilheira foi mensurado partindo de trinta coletores cônicos. A taxa de decomposição da serapilheira foi quantificada por meio de 36 sacolas de decomposição instaladas na área. Para avaliação da fertilidade do solo foram coletadas amostras nas profundidades de 0-5, 5-10 e 10-20 cm. A produção total de serapilheira foi de 7,9 Mg ha-1, sendo a maior deposição verificada no mês de novembro e a menor em junho. A fração foliar foi a de maior contribuição em relação às demais. A taxa de decomposição da serapilheira foi 40% em 7 meses de observação, seguindo modelo exponencial. Verificou-se comportamento diferenciado quanto à liberação de N, P e K. Com exceção do fósforo, os maiores valores de nutrientes, carbono e H+Al foram observados na camada superficial.Universidade Federal de Santa Maria2008-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/42810.5902/19805098428Ciência Florestal; Vol. 18 No. 4 (2008); 443-454Ciência Florestal; v. 18 n. 4 (2008); 443-4541980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/428/305Pereira, Marcos GervasioMenezes, Luis Fernando Tavares deSchultz, Nivaldoinfo:eu-repo/semantics/openAccess2017-05-09T12:05:02Zoai:ojs.pkp.sfu.ca:article/428Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-09T12:05:02Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
