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
Soil carbon fractions in response to mineral and organic fertilizer types and rates. Abstract: The use of organic fertilizers from pig slurry and poultry litter can increase soil organic carbon and crop productivity. This study aimed to evaluate soil organic carbon fractions and corn... ... Repositório: BDPA Ano de publicação: 2023
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
Stock of organic carbon in spodic horizons of Brazilian Spodosols. Soils classified as Spodosols in Brazil occur at different landscapes, from coastal plains to high altitude areas. Although they are present in different environments, these soils are formed mainly un... ... Repositório: BDPA Ano de publicação: 2019
Particulate organic carbon in agrosystems in the brazilian Semiarid. Drylands cover about 40% of the planet, in which 44% are occupied with cultivated systems. Covering 45% of Brazilian Semiarid the grasslands are main land use this region. In order to increase biomass... ... Repositório: BDPA Ano de publicação: 2018
Trees and grass contribution to soil organic carbon in agroforestry systems. Agroforestry systems have the potential to enhance carbon (C) sequestration in soil compared with treeless (agricultural) systems (Montagnini & Nair, 2004). When one type of vegetation is replaced wit... ... Repositório: BDPA Ano de publicação: 2015
Sub-surface soil organic carbon stock affected by tree lines in an oxisol under integrated crop-livestock-forestry in the Southern Amazon. The carbon (C) removed from the atmosphere through photosynthesis may be finally transferred into the soil. Soil organic C storage (SOC), therefore, is an important indicator of the capacity of a prod... ... Repositório: BDPA Ano de publicação: 2017
Total and particulate contents and vertical stratification of organic carbon in agroforestry system in caatinga. The objective of this work was to evaluate the variation in total and particulate organic carbon contents, carbon vertical stratification, and sensitivity index of organic matter fractions in soils wi... ...

Soil organic carbon accumulation in a Mollisol amended with mineral and organic fertilizers under conventional tillage and no-till systems. Repositório: BDPA Ano de publicação: 2013
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
