The role of soil organic matter in sustainable crop production in the Tropics. Soil organic matter has long been recognized as important indicator of soil productivity. Repositório: BDPA Ano de publicação: 2011
Organic matter content and composition in a sandy loam Amazonian Acrisol as affected by soil management. The agricultural production in the State of Acre (Brazilian Amazon Southwest) is still very incipient and, so far, none investigation about the effect of soil management systems on organic matter (OM)... ...

Management impacts on soil organic matter of tropical soils. Increased soil organic matter (SOM) improves the cation exchange capacity of tropical weathered soils, and liming is required to achieve high yields in these soils. Despite a decrease in SOM in the sh... ... Repositório: BDPA Ano de publicação: 2015
Methods of soil organic carbon determination in Brazilian savannah soils. Several methods exist for determining soil organic carbon, and each one has its own advantages and limitations. Consequently, a comparison of the experimental results obtained when these methods are e... ... Repositório: BDPA Ano de publicação: 2014
Relationships between labile soil organic carbon fractions under different soil management systems. ABSTRACT: The study of labile carbon fractions (LCF) provides an understanding of the behavior of soil organic matter (SOM) under different soil management systems and cover crops. The aim of this stu... ... Repositório: BDPA Ano de publicação: 2016
No silver bullet for digital soil mapping: country-specific soil organic carbon estimates across Latin America. Country-specific soil organic carbon (SOC) estimates are the baseline for the Global SOC Map of the Global Soil Partnership (GSOCmap-GSP). This endeavor is key to explaining the uncertainty of global... ... Repositório: BDPA Ano de publicação: 2018
Can soil organic carbon pools indicate the degradation levels of pastures in the Atlantic Forest biome. In Brazil, a large part of the Atlantic Forest was deforested in pastures, which were developed on the basis of natural fertility and organic matter content of the new deforested soil. However, as tim... ... Repositório: BDPA Ano de publicação: 2014
Evolution of the soil organic matter content after 15 years of crop livestock system. Soil organic matter (SOM) is sensitive to changes in land use and is a key indicator of soil quality. This work evaluates the evolution of the organic matter of an oxisol under a crop-livestock integr... ... Repositório: BDPA Ano de publicação: 2021
Soil organic carbon temperature sensitivity of different soil types and land use systems in the Brazilian semi-arid region. Quantifying the sensitivity of soil organic matter decomposition (SOM) to global warming is critical for predict future impacts of climate change on soil organic carbon stocks (SOC) and soil respirati... ... Repositório: BDPA Ano de publicação: 2019
Losses and gains of soil organic carbon in grasslands in the Brazilian semi-arid region. Studies show that soil organic carbon (SOC) decreases between 3 % and 9 % in degraded grasslands in tropical regions, mainly due to the absence of techniques to enhance carbon contribution to soils. T... ... Repositório: BDPA Ano de publicação: 2021
