Resumo: Litter production and nutrient deposition were assessed in a four year old (Grevillea rubusta Cunn) plantation in Quedas do Iguaçu, southwestern of State Paraná. The trial was established on soil classified as Haplustox (LATOSSOLO VERMELHO Distroférrico). The results showed the following features: i) Grevillea produces a large amount of litter (1,267 Kg/ha); more than various Pinus and Eucalyptus atands in similar conditions; ii) The nutrient levels in the litter are not correlated whith volume of wood produced; (the only exception was the decrease of the level of P as volume increased; iii) A positive and significant (>90,0%) correlation was evident between volume of wood produced and amount of nutrients in the litter. iv) The largest amount of litter was produced by Fine Flower provenance, and the smallest by Albert River; v) Control plots deposited the largest amount of K and Zn while other nutrients (N, P, Ca, Mg, Cu, Fe and Mn) were deposited in larger amounts by the Fine Flower provenance.

Os resultados possibilitaram as seguintes conclusões: 1) A grevilea produz em média 10267 kg de serapilheira por hectare/ano, superando as produções observadas em povoamentos de Pinus e Eucalyptus. 2) A concentração dos macronutrientes na serapilheira não tem relação com o crescimento volumétrico, exceto de P, que se apresenta em maior concentração em povoamentos com a menor produção volumétrica de média. 3) As procedências mais produtivas em madeira tenderam a depositar, pela serapilheira, as maiores quantidades de macro e micronutrientes no solo. A procedência Fine Flower foi a que apresentou a maior deposição de serapilheira, enquanto que a menor foi observada na procedência Albert River. As maiores concentrações de N, K e Zn foram registradas na testemunha; as de Ca na procedência Porter’s Gap ; as de P, Mg e Cu na Albert River e as de Fe e Mn pela Fine Flower. Os maiores conteúdos de N, P, Ca, Mg, Cu, Fe e Mn foram obesrvados na procedência Fine Flower, e os de K e Zn na testemunha. Apenas Mg e Mn em nível de concentração e Cu e Mn em nível de conteúdo mostraram diferenças significativas.Embrapa Florestas2004-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1597Pesquisa Florestal Brasileira; n. 48 (2004): jan./jun.; 75-91Pesquisa Florestal Brasileira; No. 48 (2004): jan./jun.; 75-911983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1597/650Martins, Emerson GonçalvesFerreira, Carlos AlbertoNeves, Edinelson Jsosé MacielInoue, Mario Takaoinfo:eu-repo/semantics/openAccess2018-03-22T17:55:25Zoai:pfb.cnpf.embrapa.br/pfb:article/1597Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-03-22T17:55:25Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
