Soil properties and variability of tracheid dimensions and wood density in Pinu...
Corrêa, Robson Schaff; Bellote, Antonio Francisco JuradoThe understanding of wood quality in relation to different forest sites is of fundamental relevance in current timber market. There are only few studies available concerning soil and wood quality of tropical pinots. So, the goal of this work was to characterize tracheid dimensions and wood density of Pinus caribaea var. hondurensis, correlating these variables with soil properties at different sites. Discs were...
Soil Physical and Chemical Attributes and Their Relation to Pinus taeda Growth ...
Bellote, Antonio Francisco Jurado; Dedecek, Renato AntonioIn order to evaluate the effect of soil chemical and physical attributes on the productivity of 20 year-old Pinus taeda stands planted on different soil types and with different growth rates, four sites were selected based on previous inventory, in two municipalities in the State of Paraná. Experimental plots were established on these areas where dominant trees were selected. Data on DBH and height were recorde...
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...
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...
Variables of briquetting process and quality of forestry biomass briquettes
Furtado, Thielly Schmidt; Valin, Marina; Brand, Martha Andreia; Bellote, Antonio Francisco JuradoIn the quest for recovery of waste generated from forest production to the process of industrial transformation of the biomass it was developed the process of briquetting. The cluster of wood particles facilitates the operations of handling of combustible material in addition to concentrating the available energy in terms of volume. The purpose of this study was to evaluate whether the raw material affects the ...
Biometric characteristics and seedlings nutrition of Pinus taeda under salinity...
Maeda, Shizuo; Silva, Helton Damin da; Bellote, Antonio Francisco JuradoThe application of cellulosic waste in forest plantations is an alternative to disposal, but more studies are necessary to confirm the safity of this disposal. The response of Pinus taeda L. to salinity in Humic Distrocryept was evaluated. In plantation, the seedlings were assessed for their height and stem diameter (SD), and at 120 days, were assessed the SD, height, dried root biomass (DRB), shoot (DBS) and t...
Dendronutrition as a tool to evaluate Pinus taeda wood productivity and quality
Bellote, Antonio Francisco Jurado; Tomazello Filho, Mario; Dedecek, Renato AntonioThe objective of this work was to evaluate the effect of mineral nutrients on tree growth and wood quality of Pinus taeda, on commercial plantation at 20 years after planting, on different soil types. Experimental plots were set, and from trees representing each population, stem disks were collected at different heights. Treegrowth, wood quality and growth ring parameters – tracheids diameter and radial density...
Changes in chemical characteristics of a Litholic Humic Neosol grown with Pinus...
Maeda, Shizuo; Silva, Helton Damin da; Bellote, Antonio Francisco JuradoThe aim of this work was to evaluate, in vase, the effect of cellulosic residue in soil and chemical characteristics of effluents resulting from that application in Litholic Humic Neosol layers collected in the 0 to 10 and 10 cm to 30 cm. Doses of sludge, equivalent to 0, 10, 20, 40 and 80 Mg ha-1 were implanted in a randomized design. Aliquots corresponding to doses of sludge, collected on the treatment were m...
