This study aimed to identify the best shade level for the growth of Schizolobium parabyba var. amazonicum and Eucalyptus urograndis seedlings to obtain more resilient seedlings with higher quality. We used an entirely randomized design was used, in a 2 x 4-factor scheme, with two species and four levels of shading, comprising 5 repetitions and 6 plants per repetition, totaling 30 plants per treatment. The four shading levels were characterized as follows: T1 (full sun), T2 (50%-shading screen), T3 (plastic), T4 (50%-shading screen plus wool blanket). For the production of Eucalyptus urograndis seedlings, it is recommended an unshaded environment, since one variable showed a significant difference. For the Schizolobium parahyba var. amazonicum species, it is suggested to produce it under shade, where is was achived (50% together with the wool blanket), better results for the most variables.
本研究旨在确定亚马孙副半裂叶菌和尾巨桉幼苗生长的最佳遮荫水平，以获得更具抗逆性和更高品质的幼苗。我们采用完全随机设计，在2 × 4因素方案中，采用两个物种和四个遮阳水平，包括5次重复，每次重复6株，每次处理共30株。4个遮阳等级分别为:T1(全日照)、T2(50%遮阳屏)、T3(塑料屏)、T4(50%遮阳屏加毛毯)。在桉树幼苗生产中，由于有一个变量表现出显著的差异，因此建议在无遮蔽的环境中进行生产。对于amazon Schizolobium parahyba var. amazonum，建议在遮荫下生产，在遮荫下可以达到50%(与羊毛毯一起)，对大多数变量都有较好的效果。

The present study aimed to characterize medium density particleboard manufactured with CCB treated particles of Pinus sp. wood specie and alternative mixed vegetal oil-base bicomponent polyurethane resin. For this, three different resin concentrations (10 %, 12 % and 15 %) were used in combination with the presence or absence of the CCB preservative, resulting in six distinct treatments. The particleboards were produced according the Brazilian Standard – NBR and evaluated according European standards – EN. The results met the requirements of NBR and EN. The technical feasibility of making panels with those materials used were proved and the quality of the product according to its performance were verified, indicating the possibility to use alternative bicomponent polyurethane resin from mix vegetal oil. Statistical analysis demonstrated that adhesive and preservative factors and the interaction between them were significant on physical and mechanical properties.

The aim of this study was to evaluate the distribution of chemical and physical fractions of soil organic matter (SOM) in anthropic horizons of soil profiles in the west of Pará. The highest total organic carbon values were observed in the superficial horizons, especially in the antrópico LAd and antrópico CHd (45.0g kg-1). Were observed predominance of recalcitrant organic material. It appears that most of the C found in the SOM fractions is associated with C stabilization mechanisms such as the recalcitrance provided by the presence of pyrogenic coal, in addition to its ability to present carboxylic groups that increase its interaction with the mineral fraction of the soil, characterizing the mechanism of chemical protection. It is observed that the SOM fractions can function as indicators that contribute to better understanding of the soil carbon dynamics in soils with antrópico horizons.
