1. Mapping of areas suitable for the application of biosolids in the Quadrilátero Ferrífero region, Minas Gerais, Brazil
Abstract The recovery of degraded areas is imperative for the sustainability of mining activities. The main action implemented to improve the chemical, physical and biological conditions of soils, tailings and sterile deposits is the incorporation of organic material. Biosolids (hygienized sewage sludge) are among the organic materials that can be applied. H

2. MANEJO DE RESIDUOS DE Eucalyptus grandis Hill ex Maiden EN SITIOS CONTRASTANTES
ABSTRACT In northeastern Argentina, very little is known about the impact of various techniques of management of residues from forest harvesting on soil properties. We carried out this study in two sites in Entre Ríos Province (Argentina): post-harvest of Eucalyptus grandis Hill ex Maiden stands in an Aquic Hapludert (S1) and in a Fluventic Hapludoll (S2).

3. High levels of β-xylosidase in Thermomyces lanuginosus: potential use for saccharification
ABSTRACT A new strain of Thermomyces lanuginosus was isolated from the Atlantic Forest biome, and its β-xylosidases optimization in response to agro-industrial residues was performed. Using statistical approach as a strategy for optimization, the induction of β-xylosidases activity was evaluated in residual corn straw, and improved so that the optimum cond

4. Decomposição de resíduos da colheita e transferência de carbono para o solo em plantações de eucalipto / Harvest residue decomposition and carbon transference to the soil in eucalypt plantations
In Brazil, eucalyptus is planted in regions with different climate and soil conditions, which affect harvest residue decomposition and the rate of carbon transference fromresidues (Cres) to the soil, hence influencing soil organic matter (SOM) content. SOM is considered one of the most important indicators of soil quality and forest production sustainability

5. CALIDAD DEL CARBONO ORGÁNICO DEL SUELO EN DIFERENTES TÉCNICAS DE MANEJO DE RESIDUOS FORESTALES
ABSTRACT Different harvest techniques and residue management can cause changes in the quantity and quality in soil organic matter (OM). This study aims to assess changes in concentration and in the quality of the OM, in an Ultisol with differents forest residue managements at the beginning of the second rotation. The treatment was: a) elimination of harvest

6. A biodegradation study of forest biomass by Aspergillus niger F7: correlation between enzymatic activity, hydrolytic percentage and biodegradation index
Aspergillus niger F7 isolated from soil was found to be the potent producer of cellulase and xylanase. The residue of forest species Toona ciliata, Celtris australis, Cedrus deodara and Pinus roxburghii was selected as substrate for biodegradation study due to its easy availability and wide use in industry. It was subjected to alkali (sodium hydroxide) treat

7. Resíduo da colheita de eucalipto e fontes de cálcio na agregação do solo e na estabilização da matéria orgânica / Crop residue of eucalyptus and calcium sources on soil aggregation and stabilization of organic matter
The interaction of organic compounds with divalent cations such as calcium (Ca) may improve soil aggregation and polymerise the organic molecules, forming metal-organic complexes more stable. The effectiveness of Ca on the aggregation in forest soils, in field conditions, and the influence of different sources of Ca in decomposing residues of eucalyptus and

8. Study for use the wastes of the paper manufacture in the road construction / Estudo para a utilização de resíduo da fabricação de papel na construção rodoviária
The paper and pulp industry represent one of the most expressive industrial sector around the world, being of great importance to the world economy. In South America, because of the wide forest resources, Brazil and Chile are the largest pulp-producing. Brazil produces around 6 million tons of pulp per year, among which 98% of the pulp are produced by the bl

9. Avaliação da funcionalidade do solo em sistemas florestais enriquecidos com leguminosas. / Evaluation of soil functionality in forest systems enriched with leguminous trees.
The study was conducted in an area of abandoned pasture, originally under the cover of the Atlantic Forest, to evaluate the process of succession and restoration of degraded areas. The area was located in Valença municipality, State of Rio de Janeiro Brazil. In 2001 it was conducted a planting of nitrogen fixing leguminous trees in different proportions: 0%

11. Fractions of organic matter and decomposition of eucalypt harvest residues in Coastal Plain soils of Bahia, Brazil / Frações da matéria orgânica e decomposição de resíduos da colheita de eucalipto em solos de Tabuleiros Costeiros da Bahia
Eucalypt is the most planted tree in Brazil and to maintain a sustainable forest production it is fundamental do understand the processes of litter decomposition and the impact of eucalypt cultivation on soil organic matter (SOM) fractions. The conversion of planted pastures in eucalypt plantations alters the labile and humified pools of SOM, but little is k

12. Ecotoxicologia de um sistema florestal de eucalipto tratado com lodo de esgoto / Ecotoxicology of eucalyptus forest system treated with sewage sludge
The application of sewage sludge in forest systems quests the improvement of the production, favoring the physical, chemistries and biological characteristics of the soil and of the plants. However, the sludge can contain pathogen and, organic and inorganic toxics elements, and the effect of these pollutants in the soil and in the plant is still unknown. It
