Unweathered wood biochar impact on nitrous oxide emissions from a bovine-urine-amended pasture soil
(Soil Science Society of America, 2010)
Low-temperature pyrolysis of biomass produces a product known as biochar. The incorporation of this material into the soil has been advocated as a C sequestration method. Biochar also has the potential to influence the ...
Diurnal fluctuations of dissolved nitrous oxide (N₂O) concentrations and estimates of N₂O emissions from a spring-fed river: implications for IPCC methodology
(Blackwell Publishing, 2007)
There is uncertainty in the estimates of indirect nitrous oxide (N₂O) emissions as defined by the Intergovernmental Panel on Climate Change (IPCC). The uncertainty is due to the challenge and dearth of in situ measurements. ...
Comparison of measured and EF5-r derived N₂O fluxes from a spring-fed river
(Blackwell Publishing, 2006)
There is considerable uncertainty in the estimates of indirect N₂O emissions as defined by the Intergovernmental Panel on Climate Change's (IPCC) methodology. Direct measurements of N₂O yields and fluxes in aquatic river ...
Lime and soil moisture effects on nitrous oxide emissions from a urine patch
(Soil Science Society of America, 2004)
Liming has been mooted as a mitigation option for lowering soil N₂O emissions. This study investigated the effect of soil pH and soil water content on N₂O and N₂ emissions following the addition of synthetic urine (500 kg ...
A laboratory study of bacteria-facilitated cadmium transport in alluvial gravel aquifer media
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Colloids, including bacteria, can dramatically accelerate the transport of heavy metals in ground water. Batch and column experiments were conducted to investigate adsorption of cadmium (Cd) onto Bacillus subtilis spores ...
