Methods of soil organic carbon determination in Brazilian savannah soils. Author(s): MARCHÃO, R. L.; MADARI, B. E.; SOUZA, D. M. de 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
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
Emission of CO2 from biochar-amended soils and implications for soil organic carbon. Author(s): SAGRILO, E. 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
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Author(s): SAGRILO, E. 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... ...

Trees and grass contribution to soil organic carbon in agroforestry systems. Author(s): TONUCCI, R. G. 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 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
Preparation and characterization of biodiesel industry waste partially carbonized material in order to produce an organic soil conditioner. Author(s): NOVOTNY, E. H. 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... ...

Organic carbon decomposition in soil amended with organic compost from slaughterhouse residues. Author(s): SOUZA, H. A. de; TANIGUCHI, C. A. K. Repository: BDPA Publication year: 2018
Soil organic carbon in the brazilian semi-arids tropics. Author(s): GIONGO, V.; MENDES, A. M. S.; GAVA, C. A. T.; CUNHA, T. J. F. The Brazilian semi-arid tropics occupies an area of 969,589 km2 that represents 11% of the national territory and the Caatinga is its most representatives Biome with an area of 844.453 km². However, a... ... Repository: BDPA Publication year: 2011
Predicting soil organic carbon dynamics of integrated crop-livestock system in Brazil using the CQESTR model. Author(s): MADARI, B. E.; LEITE, L. F. C.; MACHADO, P. L. O. A.; CARVALHO, M. T. M. Land degradation and reduction in productivity have resulted in losses of soil organic carbon (SOC) in agricultural areas in Brazil. Our objectives were to 1) evaluate the predictive performance of CQ... ... Repository: BDPA Publication year: 2022
