Resumo: | The aim of this project was to evaluate the Regenerative and Analogous Agroforestry Systems (SAFRA) on environmental sustainability, using as indicators the biomass increase or accumulation and nutrients deposition through litter arboreal species. This work is part of PRODETAB/EMBRAPA - 39th Project – and was developed in Goura Vrindávna Farm, Paraty - RJ. 28 multipurpose arboreal species were cultivated in three agroforestry treatments, Minimum SAFRA (simplified system of the banana culture enrichment), Absolute SAFRA (dense and diversified system) and Modified SAFRA (the same composition of the latter SAFRA plus soil fertilization). For evaluating nutrients deposition through litter fifteen months after planting, samples of three Safra and two control treatments, banana culture and area in fallow, were collected with 625cm2 collectors. Macro and micronutrients determinations were done in the samples. The Minimum SAFRA was the system that deposited the greatest weight in litter (32.4 t.ha-1) and the greatest content of micro and macronutrients. Excepting C and H, N was the one which presented greatest content in the five treatments, and Fe was the micronutrients of major deposition. The vegetation pruning in the SAFRA benefited the nutrients cycling and contributed to its content elevation in litter. Considering the nutrients deposition through litter, the SAFRAs were the most promissory systems in the re-establishing of these ecological functions, when compared to area in fallow and banana monoculture. |

Este trabalho faz parte das ações do PRODETAB - projeto 039 e foi desenvolvido na Fazenda Goura Vrindávna, Paraty, RJ. Foram plantadas 28 espécies arbóreas de múltiplos usos em três tratamentos agroflorestais, Safra Mínimo (sistema simplificado de enriquecimento de bananal), Safra Absoluto (sistema adensado e diversificado) e Safra Modificado (mesma composição do anterior e com adubação do solo). Para a avaliação do aporte de nutrientes via serrapilheira; foram coletadas amostras nos três tratamentos Safras e em dois tratamentos testemunhas (Bananal e Capoeira) por meio de coletores de 625 cm2, 15 meses após o plantio. Nas amostras, foram feitas as determinações dos teores e conteúdos de micro e macronutrientes. O Safra Mínimo foi o sistema que depositou maior peso de serrapilheira (32,4 Mg ha-1) e aportou maiores conteúdos de micro e macronutrientes. Com exceção do C e H, o N foi o que apresentou os maiores conteúdos nos cinco tratamentos, e em relação aos micronutrientes, o Fe foi o elemento de maior aporte. A poda da vegetação nos Safras favoreceu a ciclagem de nutrientes e contribuiu para elevação dos conteúdos destes na serrapilheira. Os Safras, sob o aspecto do aporte de nutrientes via serrapilheira, foram os sistemas mais promissores na recomposição dessas funções ecológicas, quando comparados à Capoeira e monocultura de banana.Universidade Federal de Santa Maria2007-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/194410.5902/198050981944Ciência Florestal; Vol. 17 No. 2 (2007); 129-136Ciência Florestal; v. 17 n. 2 (2007); 129-1361980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1944/1186Silveira, Nina DuartePereira, Marcos GervasioPolidoro, José CarlosTavares, Sílvio Roberto de LucenaMello, Rodrigo Barcelarinfo:eu-repo/semantics/openAccess2017-05-12T17:31:17Zoai:ojs.pkp.sfu.ca:article/1944Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-12T17:31:17Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
