Efeitos da aplicação de composto orgânico de lixo urbano e de fertilizante mine...
Andrade, Guilherme de CastroABSTRACT Large quantities of organic wastes are produced mainly in big cities, annually. There is urgent demand for safe and possibly economic practices for its use. Forest plantations have been studied as a potential ecosystem able to absorb organic residues as fertilizers or soil conditioners. This study evaluated the effects of the application of 15 tons/ha of composted organic waste of the city of São Paulo...
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...
Carbon Accumulation in Pinus taeda Estimated by X-rays Densitometry and Trunk A...
Bellote, Antonio Francisco Jurado; Dedecek, Renato Antonio; Lavoranti, Osmir José; Tomazello Filho, Mario de Castro; Andrade, Guilherme de CastroThe objective of this work was to evaluate Pinus aeda growth and based on X-ray methods of densitometry and bole analyses to develop mathematical models to estimate carbon amount accumulated on trees of different ages varying on DBH. Five P. taeda plantations were selected on sites of different soils, thinning intensity and growing rate. On each site dominant trees were selected and discs cuts from different h...
Site evaluation and productivity of a 3-year old stand of Eucalyptus urograndis...
Andrade, Guilherme de Castro; Bognola, Itamar Antonio; Bellote, Antonio Francisco Jurado; Franciscon, Luziane; Waterloo, Maarten JohannesPlantation forests in Brazil cover 7 million hectares, which represents 1% of the country (68% of Eucalyptus and 25% of Pinus plantations). The aim of this study was to evaluate a Eucalyptus urograndis plantation. High levels of Ca and Mg in the soil suggest that limestone had leached into the soil profile. The soil resistance down to 60 cm depth in the row of planting was lower than the inter-row space, indica...
Characterization of Substrates Elaborated with Organic Residues to Produce Fore...
Maeda, Shizuo; Dedecek, Renato Antonio; Agostini, Raul Bortolotto; Andrade, Guilherme de Castro; Silva, Helton Damin daConsidering the need for viable options for destination of waste from agricultural and agriindustries activities waste from logging and brewing industries and goat dregs previously composted, with potential foruse as substrates for the production of seedlings of trees were characterized chemically and physically. The treatments had consisted of the following mixtures: S1) commercial product for substratum (Plan...
Phosphate and potash fertilization on Acacia mearnsii De Wild. (Black wattle) p...
Andrade, Guilherme de Castro; Bellote, Antonio Francisco Jurado; Ferreira, Carlos Alberto; Silva, Helton Damin daAcacia mearnsii is the third forest species more planted in Brazil, especially in small farms at Rio Grande do Sul State. The species is also known as black wattle and is important as a source of tannin, timber, pulpwood and rayon. Its fast growth results in high demand of nutrients and fertilization is necessary to keep site productivity. In this paper it is reported the results of the application of four dose...
Growth Eucalyptus dunnii as effected by phosphorus fertilization and pulp and p...
Andrade, Guilherme de Castro; Silva, Helton Damin da; Bellote, Antonio Francisco Jurado; Ferreira, Carlos AlbertoFast 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 nutrien...
