Soil carbon stock (SCS) assessment and monitoring is required to evaluate soil health, assess soil ecosystem services, support carbon credit accounting, and guide public policy. In all cases, baseline SCS values are essential, yet they are hardly ever available across large regions, e.g...
Eucalyptus ssp. (eucalyptus) is commonly used in integrated crop-livestock-forestry and livestock-forestry systems. Acacia mangium (acacia) grows as fast as eucalyptus in tropical conditions and is capable of fixing N2 from the atmosphere. Both species differ in terms of litter quality: eucalyptu...
Para monitorar o carbono (C) no solo, o Protocolo de Medição, Relato e Verificação (MRV) recomenda que além de quantificar os teores e estoques de C no solo também seja quantificada a fração lábil da matéria orgânica mais sensível às mudanças no uso da terra, como o&...
O reflorestamento compensatório emerge como uma estratégia contra as mudanças climáticas, consistindo no plantio de árvores em áreas degradadas ou desmatadas para neutralizar as emissões de carbono. As árvores sequestram o C, armazenando-o em sua biomassa e no solo. Este estudo se conce...
Measuring soil carbon content dry combustion or wet chemistry requires extensive sample preparation and labor, making these methods too costly for monitoring soil carbon. Visible-near infrared (VisNIR) spectroscopy expedites soil carbon assessment with minimum sample preparation and reduced labor. The...
Carbon is a key element in the contemporary context of climate change, and its cycle in nature is interconnected with various ecosystem functions. This study uses soil organic carbon (SOC) stock and land use/land cover (LULC) maps from the MapBiomas project to evaluate SOC...
Soil bulk density is an essential property for determining soil carbon stock and sequestration, influencing other soil properties and functions. It is a difficult attribute to measure, and therefore, many studies have used statistical and computational methods to model the variation of ...
Gleysols are typical mineral hydromorphic soils, characterized by a gley horizon near the surface due to prolonged saturation. These soils originate from a range of unconsolidated fluvial, marine, and lacustrine sediments of Pleistocene or Holocene age. Their texture varies from sandy to...
The Brazilian semiarid region faces critical challenges of water scarcity, soil degradation, and the intensified impacts of climate change, threatening food security and the continued survival of families in rural areas. Against this backdrop, underground dams emerge as an innovative and eff...
Soil organic carbon (SOC) is a key indicator for assessing pasture degradation. This study presents an integrated, field-based approach to analyzing SOC dynamics in pastures of Rio de Janeiro state (Brazil). Unlike methods based exclusively on remote sensing or modeling, our analysis is...
