1. Soil Microbial Attributes Under Agroforestry Systems in the Cerrado of Minas Gerais
ABSTRACT The aim of this study was to evaluate the soil microbiological attributes of two Agroforestry Systems (AFS) in the city of Grão Mogol-MG considering two soil classes (Udox and Aqualf). Three composite samples were collected from the 0-5 cm soil depth layer. Each sample was subsequently divided into five replications to evaluate the carbon of soil

2. Soil CO2 Efflux Measurements by Alkali Absorption and Infrared Gas Analyzer in the Brazilian Semiarid Region
ABSTRACT The CO2 emission from the soil surface, commonly referred to as soil CO2 efflux (ECO2) or soil respiration, is the sum of processes that include root respiration and microbial activity. Measuring this evolution is important to establish sustainable land use models and to estimate global fluxes of carbon, which affect climate change. Despite its impo

5. FLUXO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE PREPARO DO SOLO E ROTAÇÃO DE CULTURAS NO PLANALTO DO RIO GRANDE DO SUL / GREENHOUSE GASES FLUX IN SYSTEMS OF SOIL TILLAGE AND CROP ROTATION IN THE PLANALTO REGION OF RIO GRANDE DO SUL
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

6. Indicadores microbiológicos e bioquímicos da qualidade do solo em transição para cultivo orgânico de feijoeiro comum (Phaseolus vulgaris L.) / Microbiological and biochemical indicators of the quality of ground transitioning to organic cultivation of common bean (Phaseolus vulgaris L.)
The soil quality indicators analyses during and after the transition period of conventional to organic production system are very important to evaluated the sustainability of agricultural systems. Soil microbiological and biochemical indicators shall quickly indicate changes occurred on both, soil management and production systems. The objective of this work

7. EMISSÕES DE CO2 DO SOLO SOB PREPARO CONVENCIONAL E PLANTIO DIRETO EM LATOSSOLO VERMELHO DO RIO GRANDE DO SUL / SOIL CO2 EMISSIONS IN CONVENTIONAL AND NO-TILL SYSTEMS IN A RHODIC HAPLUDOX IN RIO GRANDE DO SUL
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
