Caracterização tecnológica da madeira de Eucalyptus benthamii para produção de ...
Alves, Isabel Cristina Nogueira; Gomide, José Lívio; Colodette, Jorge Luiz; Silva, Helton Damin daO objetivo deste trabalho foi avaliar a qualidade tecnológica da madeira de Eucalyptus benthamii para produção de celulose kraft. Suas características foram comparadas com as de um híbrido de Eucalyptus grandis x Eucalyptus urophylla que é, provavelmente, o clone mais plantado no Brasil e, portanto, de grande importância no setor nacional de celulose e papel. Determinaram-se a densidade básica, composição quími...
Modelos matematicos para a estimativa da biomassa e do conteudo de nutrientes e...
Silva, Helton Damin daOrientador: Carlos Bruno Reissmann; Tese (Doutorado) - Universidade Federal do Parana; Área de concentração: Silvicultura; O acúmulo e a ciclagem de nutrientes em florestas plantadas é fundamental para o estabelecimento de práticas de manejo que favoreçam a manutenção da produtividade do sítio florestal. O recrutamento, acúmulo e a liberação de nutrientes depende da idade e do estágio de desenvolvimento das árv...
Dendroenergetical characterization of Eucalyptus benthamii trees
Lima, Edson Alves de; Silva, Helton Damin da; Lavoranti, Osmir JoséEucalyptus benthamii has shown to be the most proeminent specie for regions with frost incidence. The objective of this work was to classify selected Eucalyptus benthamii trees for breeding by importance ordening dendrometric and energetic characteristics, useful for this work 91 disks of DBH were collected, from three plantations at Guarapuava municipality, Parana state, with geographical coordinates 25º 23’ 2...
Evaluation of Seedlings Gowth of Eucalyptus badjensis in Substrata from Compost...
Maeda, Shizuo; Andrade, Guilherme de Castro; Ferreira, Carlos Alberto; Silva, Helton Damin da; Agostini, Raul BortolottoThe aim of this work was to evaluate the seedling growth of Eucalyptus badjensis Beuzev. & Welch in substrata prepared from different residues: pulp and paper mill wastes (organic sludge and cellulose mill liquid alkaline liquor), brewery malt and also goat manure. The experiment was carried out in the seedlings nursery of the Embrapa Florestas, in Colombo, Paraná. The organic sludge, cellulose mill liquid alka...
Effects of Urban Waste and Mineral Fertilizers Applications on Eucalyptus grand...
Andrade, Guilherme de Castro; Bellote, Antônio Francisco Jurado; Silva, Helton Damin da; Dedecek, Renato Antônio; Gava, José Luiz LuiForest plantations have been studied as a potential ecosystem able to absorb organic residues as fertilizers or soil conditioners. This study evaluate the effects of the application of composted organic waste and mineral fertilizers in a Eucalyptus grandis (W. Hill ex Maiden) plantation with 86 months of age in Neossolo Quartzarênico. It was analyzed wood production, litter decomposition and the physical and ch...
Nutrient Accumulation in Eucalyptus grandis Biomass and Litter Using Urban Wast...
Andrade, Guilherme de Castro; Bellote, Antonio Francisco Jurado; Silva, Helton Damin da; Rizzi, Nivaldo Eduardo; Gava, José LuizLarge quantities of organic wastes are produced mainly in big cities, annually. There is urgent demand for safe and possible economic practices for its use on forest plantations. This study evaluated the effects of the application of urban waste and mineral fertilizers on Eucalyptus grandis W. Hill ex Maiden plantation growing on Neossolo Quartzarênico, analyzing nutrient contents in the litter and in the above...
Prognosis of the Volume Growth of Eucalypts Trees, in Plantations, in the South...
Ferrari, Marcio Pinheiro; Ferreira, Carlos Alberto; Silva, Helton Damin da; Trevisan, RobertoThis paper deals with the prognosis of the individual volumetric growth of Eucalyptus species in the Brazilian South Region. It was accomplished in a fertilizer trial with Eucalyptus dunnii and a competition trial among species (E. bicostata, E. “cambiju” - natural hybrid, E. deanei and E. viminalis) implanted in Vila Velha, PR. The method of successive regressions, modified to the exponential form, including t...
Aethalion reticulatum (Linnaeus, 1767) (Hemiptera: Aethalionidae) in Grevillea ...
Santana, Dalva Luiz de Queiroz; Ferreira, Carlos Alberto; Martins, Emerson Gonçalves; Silva, Helton Damin daThe grevilea, Grevillea robusta (Cunn), species of the Proteaceae family, native of Australia it was introduced in Brazil and in several other countries of the world, for ornamentation, wind breaks and to shade agricultural crops. In general the grevilea has few pests in its area of natural dispersion and also in Brazil. Recently a severe infestation of the cicada Aethalion reticulatum (Hemiptera: Aethalionid...
Mineral nutrients, biomass and litter deposition on Eucalyptus plantation under...
Bellote, Antonio Francisco Jurado; Dedecek, Renato Antonio; Silva, Helton Damin daIt was evaluated the effect of different residue management systems in the plant nutrition status, nutrient contents in the litter and litter biomass yield, on Eucalyptus grandis plantation. Samples were taken on four residue management systems: (i) removal of all residues from previous harvesting and NPK fertilization; (ii) maintenance of all residues on soil surface and NPK fertilization; (iii) removal all at...
Response of Pinus taeda to ash from plant biomass in Cambissolo Humico in pots
Maeda, Shizuo; Silva, Helton Damin da; Cardoso, CamileThe aim of this work was to measure the effect of ash, collected from the boiler of a pulp mill and applied in doses equivalent to 0, 10, 20, 40 and 80 t.ha-1 on the chemical characteristics of the soil and on the development and absorption of nutrients for Pinus taeda L. seedling potted with CAMBISSOLO Humico from the 0-20 cm layer in Piraí do Sul, PR. Portions of the soil were placed in pots and aliquots of ...
