1. Nutrition of tree species in tropical dry forest and rainforest environments
ABSTRACT Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity. The objective of this study was to evaluate the nutrient utilization efficiency of N, P, K, Ca and Mg of dominant species in tropical dry forest and rainforest environ

2. Assessment of the effects of vegetational cover on the long-term stabilityof a waste rock dump
Abstract Waste rock dump reclamation includes re-grading the banks to flatten the overall slope followed by re-vegetation. These measures are required to reduce surface erosion, provide physical stability, and meet future use goals. In some cases, the presence of trees can cause localized shear zones in a waste rock dump by the load of the tree mass and the

3. Overcoming dormancy of Senna multijuga seeds with an ultrasonic probe the comparison with ultrasound and sulfuric acid baths
RESUMO: Entender a germinação é extremamente importante para produção de mudas utilizadas na revegetação de áreas degradadas. Algumas espécies são consideradas dormentes por apresentarem uma estratégia de sobrevivência para superar condições ambientais adversas. Essas sementes germinam apenas quando esse processo é interrompido, o que pode oc

4. The landscapes from Ouro Preto, Minas Gerais State: decoding in space and time
Resumo As paisagens são formadas por elementos físicos de ordem material e por elementos abstratos de ordem imaterial, assim sua gestão e planejamento devem considerar estes dois aspectos. Com o objetivo de compreender as paisagens do município de Ouro Preto, Estado de Minas Gerais, foram identificadas e classificadas as apropriações pelos atores que a

5. Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland
ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativ

6. Physical Quality of a Typic Hapludult Soil Under Forest Leguminous Trees and Pasture
ABSTRACT Revegetation with leguminous trees has been used to recover degraded areas. This study aimed to evaluate the physical quality of a Typic Hapludult soil under secondary forest, pasture and three leguminous tree species: Acacia (Acacia auriculiformis), Sabia (Mimosa caesalpiniaefolia) and Inga (Inga spp. ), in Conceição de Macabú County, Rio de Ja

7. Diversity of Arbuscular Mycorrhizal Fungi in an Amazon Environment after Mining
ABSTRACT At the Brazilian Amazon forest, studies were carried out to estimate the community of arbuscular mycorrhizal fungi (AMF), from this it was used a bioassay of dilutions of samples collected from preserved and regenerated areas after bauxite extraction. To regenerate areas, tree species were introduced and samples were taken after 2, 6, 12, and 16 ye

8. Growing Periandra mediterranea on post-mining substrate: native Fabaceae with potential for revegetation of degraded rupestrian grasslands in Brazil
ABSTRACT Recovery of degraded areas of rupestrian grasslands is hampered mainly by the limited knowledge regarding substrate management and the biology of native species suitable for revegetation of these areas. The aim of our study was to examine the establishment and growth of Periandra mediterranea in different textures of lateritic substrate from a minin

9. Reforestation of a Degraded Area with Eucalyptus and Sesbania: Microbial Activity and Chemical Soil Properties
ABSTRACT Mining activities generally affect soil quality, degrading it and creating the need for consistent environmental recovery efforts. This study evaluates the influence of monospecific and mixed stands of Sesbania virgata (S) and Eucalyptus camaldulensis (E) on the chemical properties and microbial activity of the soil in a degraded area by clay extrac

10. Reclamation of a Degraded Coal-Mining Area with Perennial Cover Crops
ABSTRACT: Studies addressing the potential of grass roots in improving the structural quality of constructed minesoils are not frequent in the literature, although they are essential for understanding the re-establishment of soil functions in the environment. The objective of this study was to quantify the root attributes of the species Urochloa humidicola,

11. Initial Recovery of Organic Matter of a Grass-Covered Constructed Soil after Coal Mining
ABSTRACT Revegetation is essential to improve the quality of constructed soils. This study investigated effects of perennial grasses on total organic carbon (TOC) stock, organic matter (OM) fractions and on quality of a recently constructed soil, after coal mining. Soil samples were collected from the 0.00-0.03 m layer two years after the beginning of the ex

12. Rhizobia Isolated from Coal Mining Areas in the Nodulation and Growth of Leguminous Trees
ABSTRACT An alternative for recovery of areas degraded by coal mining is revegetation with rapidly growing leguminous trees, which often do not establish in low fertility soils. The objective of this study was to evaluate the efficiency of native rhizobia isolated from coal mining areas in the nodulation and growth of leguminous trees. We isolated 19 strains
