The Chapadinha microregion stands out in soybean cultivation, accounting for 78% of production in eastern Maranhão. The replacement of natural vegetation with soybean farming has impacted biodiversity, regional water cycles, and ecological balance. Therefore, the aim this study was to comprehend&...
This study quantified the soil carbon content and stock in a chronosequence of an Integrated Crop-Livestock-Forest (ICLF) system in Maranhão, Brazil, comparing it with degraded pasture and reference areas. The experiment included two reference environments: secondary regenerating vegetation for approx...
A inclusão da dimensão socioambiental na avaliação de empresas tornou-se relevante nas últimas décadas do século XX quando o conceito de desenvolvimento sustentável destacou a necessidade de aliar crescimento econômico à preservação ambiental e à responsabilidade social. O desempenho econômico pa...
This study examines how Brazilian agribusiness companies adopt Corporate Socioenvironmental Responsibility (CSR) tools based on Environmental, Social, and Governance (ESG) frameworks and the Sustainable Development Goals (SDGs), evaluating their role in strengthening governance, reducing reputational risks, and ...
Objetivou-se avaliar a influência de regimes hídricos no acúmulo de biomassa do feijão-caupi. O estudo foi conduzido na área experimental da Embrapa Meio-Norte, em Teresina, PI. Os tratamentos foram cinco regimes hídricos (133,80; 191,70; 249,00; 303,00 e 357,00 mm) e duas cultivares de...
O presente estudo teve como objetivo avaliar genótipos de feijão-caupi (Vigna unguiculata) para produção de forragem, considerando-se a adaptação às condições edafoclimáticas do Semiárido do norte do Piauí. Utilizou-se o delineamento em blocos casualizados com quatro repetições. Os tratamentos incluír...
Organic matter is essential for soil health, but is depleted by conventional agricultural practices. Remotely piloted aircraft (RPA) with multispectral sensors offer an efficient and accurate alternative for monitoring soil carbon through spectral indices. In this study, the objective was to ...
In the Brazilian semi-arid region, slash-and-burn agriculture is the primary driver of soil degradation, resulting in declining crop yields and the impoverishment of rural communities. Nevertheless, smallholder farmers have adopted reforestation practices to sustain bee populations during the dry seas...
Aim of study: Conservation management is an important alternative for the mitigation of environmental problems caused by conventional agriculture; however, information about long-term benefits of conservation systems is still incipient. Simulation modeling of soil organic matter dynamics has been appl...
Nutrients and carbon cycling processes in integrated production systems are essential for agroecological sustainability in the Cerrado of Northeast Brazil. However, quantitative and process-level understanding remains limited. This study aimed to characterize off-season plant residue decomposition under differe...
