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... ... Repository: BDPA Publication year: 2018
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... ... Repository: BDPA Publication year: 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... ... Repository: BDPA Publication year: 2021
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... ... Repository: BDPA Publication year: 2014
Modelling and digital soil mapping of the organic carbon stock in the topsoil (0-10 cm) of Rio de Janeiro State, Brazil. A soil database with 431 soil profiles of Rio de Janeiro State was used in the scope of a research project entitled "Quantifying the magnitude, spatial distribution and organic carbon in soils of Rio... ...

Emission of CO2 from biochar-amended soils and implications for soil organic carbon. Soil amendment with pyrogenic organic matter (PyOM), also named biochar, is claimed to sequester carbon (C). However, possible interactions between PyOM and native soil organic carbon (SOC) may accele... ... Repository: BDPA Publication year: 2015
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... ... Repository: BDPA Publication year: 2015
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Soil amendment with pyrogenic organic matter (PyOM) can sequester carbon, increase mutualistic root symbioses with arbuscular mycorrhizal fungi and nitrogen-fixing rhizobia, and hence improve crop yie... ...

Preparation and characterization of biodiesel industry waste partially carbonized material in order to produce an organic soil conditioner. This work seeks to determine the best methods of production of partly carbonized waste of biodiesel industry - castor (Ricinus communis) meal - aimed at obtaining material comparable to organic matter... ...
