13. Leaching of Heavy Metals in Soils Conditioned with Biosolids from Sewage Sludge
ABSTRACT A promising use of biosolids is as organic fertilizer in agricultural and forestry activities. However, its composition might contain several pollutants, especially heavy metals, which may result in an increase in the concentrations of these elements in the soil and the risk of groundwater contamination. This study aimed to determine the leaching le

14. Potencialidad de varias especies para la obtención de biomasa con fines energéticos en el secano mediterráneo de Chile
Abstract In Chile, there are about 1.8 million hectares of dryland soils with severe site restrictions for agronomic and forest species growth. However, these soils can be used to establish energy crops, using forest species specially adapted to this condition. The purpose of this paper is to estimate the potential land availability in the drylands of centra

15. New Contours of the Native Vegetation Protection Law of 2012
ABSTRACT The conservation of natural resources within rural properties is a constitutional obligation. Among the social function criteria required for the exploitation of rural properties, besides the rational use and respect of working conditions, there is a need to ensure environmental protection. The current guidelines regarding the exploration and the en

16. Estimativa de impactos da extração seletiva de madeiras na Amazônia utilizando dados LIDAR
Resumo As atividades de manejo florestal são consideradas importantes para o desenvolvimento sustentável no Brasil. Tais atividades, entretanto, exigem monitoramento rigoroso que muitas vezes é de difícil operacionalização. O mapeamento das áreas afetadas pela exploração seletiva de madeira e a mensuração dos impactos decorrentes da exploração f

17. Consumption and Characterization of Forestry Biomass Used in Tobacco Cure Process
ABSTRACT The tobacco production requires annually a large volume of firewood used in the cure process of tobacco leaves, representing up to 10% of its production cost. An alternative is the use of agroindustry residues, such as sawdust or pellets. The objective of this study was to analyze the consumption and to characterize forestry biomass used in the toba

20. Sampling frequency to estimate cumulative nitrous oxide emissions from the soil
Resumo: O objetivo deste trabalho foi avaliar a influência da frequência de amostragem de gases na estimativa das emissões acumuladas de óxido nitroso (N2O) do solo. Foram avaliadas emissões de gases durante dois anos (2014-2016), em quatro sistemas: plantio de eucalipto, lavoura, pastagem e fragmento florestal. As estimativas acumuladas de N2O foram ca

21. Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants
Abstract: Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to incorporate into these baits. Moreover, leaf-cutting ants can avoid toxic baits by associating the attractant with the toxin. We e

22. Growth and quality of Handroanthus serratifolius seedlings in soils incorporating amendments and inorganic residues
ABSTRACT Rock powder and boiler ash are residues with a high potential for the fertilization of substrates to produce forestry seedlings. They are the source of macro and micronutrients, besides having an effect on soil pH. Therefore, this study aimed to evaluate the effect of the isolated application of rock power, boiler ash, dolomitic limestone and calciu

24. Fertilization of Eucalyptus Stands at Advanced Ages in Minas Gerais, Brazil
ABSTRACT This study evaluated the response to fertilization at advanced ages in Eucalyptus stands. Fertilization at advanced ages (FA) was applied in stands managed according to tall shaft and coppice regimes. All stands received operational fertilization from the company. It was used as the basis to the network of continuous forestry inventory plots (P-IFC)
