Resumo: | Fast growing plantations in Brazil, especially with Eucalyptus and Pinus species, are responsible for thousands of employs, presenting significant participation in the country economy. It also contributes to the environment by lowering the pressure over natural forests helping to preserve their natural resources. The extremely high growth rate of these forest plantations imposes high demand on water and nutrients from the soils in addition the majority of these soils are poor in nutrients. This is motive of wariness in relation to the sustainability of the future productivities. Replenishment of nutrients is necessary and use of wastes from pulp and paper mills, for this purpose are envisaged as a priority. In this paper it was evaluated, in a factorial designed trial, the effect of five doses of pulp and paper wastes (0, 10, 20, 40, 80 t/ha), and four doses of phosphorous as P2O5 (0, 28, 56, 112 g/tree). The planting was performed in the region of Ponta Grossa, state of Paraná-BR in LATOSSOLO VERMELHO-AMARELO, a chemically poor soil, very common in the so-called region of the “Campos Gerais”. Trees were implanted in 3m X 2m spacing. Phosphorous were applied in furrows between the rows at planting time, and wastes ten months latter spread over the surface and mixed in the soil by a rotating tillage tool. The results obtained 6 years after planting allowed the following conclusions: application of phosphorous and pulp and paper wastes increased wood volume substantially to the control, about 38% and 61% from the smallest to the biggest dose rate of phosphorous and among 20% to 40% for pulp and paper wastes applied; increases of 52% to 92% of productivity above the control treatments were also obtained with different combinations of P and waste. |

Do ponto de vista ambiental, contribuem para reduzir a pressão sobre as florestas nativas, concorrendo assim para a sua preservação e a dos recursos naturais nelas existentes. Esses povoamentos florestais, implantados na sua maioria em solos de baixa fertilidade, apresentam altas taxas de crescimento, necessitando de quantidades significativas de água e nutrientes do solo, o que causa preocupações com a sustentabilidade desses sistemas e com a necessidade de reposição futura de nutrientes. A utilização de resíduos para esta finalidade é considerada prioritária. Neste trabalho foram avaliados os efeitos da fertilização mineral e da aplicação de resíduo da indústria de celulose no crescimento de árvores de E. dunnii, em ensaio com delineamento fatorial, combinando 4 doses de fósforo (0; 28; 56 e 112 g de P2O5/planta) com 5 doses de resíduo (0; 10; 20; 40 e 80 t/ha). O plantio foi realizado na região de Ponta Grossa – PR, utilizando-se o espaçamento de 3 X 2 m entre plantas, em LATOSSOLO VERMELHO-AMARELO, solos de baixa fertilidade, característicos dos campos gerais do Estado do Paraná. A adubação com fósforo ocorreu no sulco, no momento do plantio, e o resíduo foi aplicado 10 meses após o plantio, a lanço, em toda a parcela, e incorporado ao solo mecanicamente, com enxada rotativa. Os resultados obtidos aos seis anos de idade permitem concluir que o E. dunnii respondeu isoladamente à adubação fosfatada e à aplicação de resíduo de celulose, em volume cilíndrico arbóreo, com ganhos em volume com relação à testemunha, de 38% a 61%, da menor para a maior dose de fósforo aplicada, e entre 20% e 40% para os níveis de resíduo testados. Estas respostas também ocorreram nas diferentes combinações de doses de fósforo com os níveis de resíduo, sendo todas superiores à testemunha, em volume cilíndrico de madeira, de 52% a 92%.Embrapa Florestas2003-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1607Pesquisa Florestal Brasileira; n. 47 (2003): jul./dez.; 43-54Pesquisa Florestal Brasileira; No. 47 (2003): jul./dez.; 43-541983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1607/638Andrade, Guilherme de CastroSilva, Helton Damin daBellote, Antonio Francisco JuradoFerreira, Carlos Albertoinfo:eu-repo/semantics/openAccess2018-03-22T17:55:17Zoai:pfb.cnpf.embrapa.br/pfb:article/1607Revistahttps://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:2018-03-22T17:55:17Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
