Nitrous oxide emission in pasture under rotational and continuous managements. Abstract: One of the most important anthropogenic methane and nitrous oxide sources in Brazil are the agricultural activities. In 2010 it was estimated that the emissions of methane (CH4) and nitrous... ... Repository: BDPA Publication year: 2016
Liming acidic soils. 1. Description of the practice. 2. Range of applicability. 3. Impact on soil organic carbon stocks. 4. Other benefits of the practice. 5. Potential drawbacks to the practice. 6. Recommendations before... ... Repository: BDPA Publication year: 2021
CH4 and N2O fluxes from planted forests and native Cerrado ecosystems in Brazil. ABSTRACT: Forest soils are N2O sources and commonly act as CH4 sinks. This study evaluated the dynamics of the CH4 and N2O fluxes of soils under Eucalyptus plantations and native Cerrado vegetation, a... ... Repository: BDPA Publication year: 2021
Distribuição dos fluxos de n2o ao longo do dia em latossolo vermelho no cerrado. Os fluxos de N2O oriundos do solo estão entre os mais relevantes para os cálculos das emissões dos GEE. A quantificação das emissões desses gases pelo solo em longos períodos normalmente são realizada... ... Repository: BDPA Publication year: 2013
Soil CO2 emission in 'Tifton 85' bermudagrass pasture fertilized with liquid pig slurry. The application of liquid pig slurry (LPS) to pastures offers potential as a fertilizer but could have a direct influence on soil CO2 emissions. This study evaluated soil carbon dioxide emissions afte... ... Repository: BDPA Publication year: 2021
Low Carbon Beef: a case study in a sandy soil from Brazilian Cerrado. Global demand for food is increasing, which pressures for greenhouse gas emissions reduction or neutralization to mitigate the climate change. In this context, Brazil has developed technologies to pro... ... Repository: BDPA Publication year: 2022
