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
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... ... 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
Comparison of H/AL stoichiometry of mineral and organic soils in Brazil. Exchangeable Al has been used as a criterion for the calculation of lime requirement in several Brazilian States. However, the laboratory method with extraction by a 1 mol L-1 KCl solution followed by... ... Repositório: BDPA Ano de publicação: 2009
Modeling of bentazone leaching in soils with low organic matter content. Abstract: The aim of this study was to estimate bentazone´s potential to leach to groundwater in the Arenosols developed from sand, Luvisols developed from loamy sand or sandy loam, and Luvisols or Ca... ...
