1. CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST
RESUMO As florestas secundárias de Mata Atlântica possuem um papel importante no contexto das mudanças climáticas por atuarem como sumidouro de carbono da atmosfera. Entretanto, essas florestas podem se transformar em fonte de carbono com o aumento da mortalidade de árvores. O conhecimento dessa mudança é possível mediante inventários florestais con

3. Organic Carbon and Physical Properties in Sandy Soil after Conversion from Degraded Pasture to Eucalyptus in the Brazilian Cerrado
ABSTRACT Soil is currently seen as the most relevant carbon sink and the most effective carbon stabilizer. In contrast, agriculture is the second largest C emitter, after burning of fossil fuels. This organic carbon (OC) introduced into the soil, mainly via organic matter (OM), is essential for several soil properties and plays an extremely important role in

4. Carbon sequestration and greenhouse gases emissions in soil under sewage sludge residual effects
The large volume of sewage sludge (SS) generated with high carbon (C) and nutrient content suggests that its agricultural use may represent an important alternative to soil carbon sequestration and provides a potential substitute for synthetic fertilizers. However, emissions of CH4 and N2O could neutralize benefits with increases in soil C or saving fertiliz

5. Química entre a microcamada superficial oceânica e os aerossóis marinhos
The sea surface microlayer (SML), although poorly understood, is important in biogeochemical cycling and sea - air exchanges; it is a source or a sink for a range of pollutants. In this paper, an overview of sampling techniques and the role of SML in biogeochemical cycles and climate is presented. The chemical and biological nature of the ocean surface film

6. Potencial uso de serpentinito no armazenamento mineral do CO2
Rising anthropogenic CO2 emissions are considered a major contributor to the greenhouse effect. There are several options for reducing atmospheric CO2 levels, and among these alternatives, Carbon Capture and Storage (CCS) has been identified as an effective and promising approach. This work investigated the feasibility of using serpentinite as a vehicle for

7. Aspectos fisiológicos e da produção do arroz em resposta ao silício / Physiological and productive aspects of rice plants according to silicon supplying
The objective of this study was to analyze the role of supplemental silicon (Si) in the biomass accumulation and grain yield of rice (Oryza sativa L.). Different experiments were carried out in which wild rice plants (japonica subsp. Oochikara - WT) and mutant defective for the absorption of Si - lsi1 (Low silicon rice 1) were raised under hydroponics condit

8. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

9. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan

10. Dinâmica do carbono e fluxo de gases do efeito estufa em sistemas de integração lavoura-pecuária na Amazônia e no Cerrado / Carbon dynamics and greenhouse gas fluxes in integrated crop-livestock systems in Amazonia and Cerrado
Changes on land use and management influence the accumulation of carbon (C) in soil and the greenhouse gas (GHG) fluxes. In Brazil, especially in Amazonia and Cerrados biomes, the native vegetation has been historically converted in pastures and agriculture causing considerable amount of GHG emissions to the atmosphere. Recently, pastures and agricultural ac

The main greenhouse gases (GHG) are the nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2), whose atmosphere concentrations increased in an unprecedented rate since the Industrial Revolution. This work aim evaluates the GEE emissions of spring/summer season in different soil management systems located in the Planalto region of Rio Grande do Sul Stat

Climatic change is associated with the increase of greenhouse gases (GHG) concentration, including carbon dioxide (CO2). Among the most important strategies to decrease global warming are decrease emissions and increase biological capture of CO2 through carbon sequestration in the ecosystems. Therefore, soils are fundamental to this strategy because dependin
