“…The organomineral fertilization provided the less acid soil and a decrease in the potential acidity value, which is in accordance with Carvalho, Moreira, Cruz, Fernandes and Oliveira (2014), who found the same benefits in olive trees fertilized with 50% of organomineral. However, these results are different from those found by Centurion, Centurion, Roque, Prado and Natale (2005), who observed a high pH under a soil management with tropical kudzu (Pueraria phaseoloide L.) associated with rubber trees compared to the management using harrow and brushcutter. Nascimento, Silva, Roberval and Silva (2005) observed a decrease in acidity using legumes such as pigeon pea.…”

Rubber tree (Hevea brasiliensis) is a native species of the Amazon biome. This species had great economic importance due to the production of latex, used to obtain natural rubber. Seeking growth in productivity with adequate management is necessary to optimize production and increase areas with rubber trees. This study aimed to verify the physical and chemical attributes of soil under three different managements and two rubber tree clones, searching for the best alternative for the general edaphoclimatic conditions of the Cerrado biome. The experiment was installed in Palmeiras of Goiás, GO, Brazil, in a randomized block design in a 2×3 factorial arrangement, consisting of two rubber tree clones (PB 312 and RRIM 600) and three management strategies (organomineral fertilizer with poultry litter, pigeon pea as green manure, and mechanical mowing-brushcutter). Physical attributes such as soil density, soil penetration resistance, soil moisture and aggregation, soil fertility, and tree development were analyzed. Statistical analyses of variance and Tukey test were carried out in order to compare the dendrometric data and physical and chemical attributes of the soil under the different treatments applied in the inter-row of rubber trees. No significant statistical differences were found among treatments and between clones in relation to soil physical attributes. However, the soil pH reduced the use of organomineral fertilizer and the clone RRIM 600 had the highest heights.

“…However, the knowledge on which management practices cause less alterations in the physical properties is still very little and it is key for a better plantation development and soil conservation. The conventional management used in the region is harrowing, with some recommendations for trimmer and green manuring (Centurion et al, 2005). However, the management techniques have great influence in soils attributes and species development.…”

“…Ribon et al (2003), when studying Oxisols and Ultisols in the area, have observed that the management with trimmer favours the increase in soils density and reduce the soil's macro porosity, eventually causing harm to tree development. On the other hand, Centurion et al (2005), when studying the influence of types of management in the soil's chemical properties and rubber tree nutritional state and development, observed that trimmer is important for the soil-plant system. Centurion et al (1995) performed a study on rubber tree development in soils from São Paulo's plateau (Oxisols and Ultisols) and have verified that those have not presented limitations in physical properties, effective depth, texture and internal drainage in this crop's development.…”

São Paulo's western plateau is a privileged region for rubber tree plantation, since it does not present favourable conditions for the development of plant disease. However, the soil in that region is still scarcely studied. This study has the objective of evaluating the effect of management practices applied between the lines of rubber trees (Hevea brasiliensis) in physic-hydric attributes of a red oxisol and redyellow ultisol, in the city of Jaboticabal-SP, in random blocks with four repetitions. The following treatments were applied between the lines: harrowing, green manure application with Pueraria phaseoloides and trimmer. The quantified data were: soil permeability, clay content, disperse clay, flocculation degree, water retention curve and total porosity, for four soil layers (0-0.10; 0.10-0.20; 0.20-0.30; and 0.30-0.40 m). The studied soils presented differences regarding water permeability for the different treatments. Higher gravimetric humidity for lower tensions in both soils was observed. Green manure with pueraria favors increase in total porosity in the studied soils, contributing for increase in total porosity, humidity and permeability.

“…These uses have already embodied in the new research, the user of Hevea brasiliensis to double-fitness, or being directed to clones for production of rubber and wood, making the crop more attractive and profitable, and as a honey plant and for the extraction oil seeds, thus also being used for fuel production (biodiesel). [1][2][3][4][5][6][7][8] For proper drying, the moisture content of wood should be adjusted gradually to the equilibrium moisture content desired. This control is done through periodic adjustments in temperature and relative humidity inside the greenhouse, given by a drying program, whose productions requires an understanding of the species drying behavior.…”

The Simpson model proposes that the rate of wood drying is directly proportional to average moisture content. In this work was done the fitting and the reproduction of drying curve forHeveabrasiliensiswood through of Simpson model and the chi-square statistical method. The curves were obtained by drying 108 specimensHeveabrasiliensiswood with size 10 mm x 20 mm x 100 mm that were drying in a laboratory kiln. The drying control was performed through gradual temperature increase in order to minimize the errors arising due the drastic loss of moisture by wood. The gravimetric method was used to evaluate the drying process, the specimens have theirs mass measured every 6 hours until the timber reached the theoretical anhydrous state. The drying curve of rubber wood obtained here can be used to estimate the drying time of this species for different kiln temperature settings.
