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 ...
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 ...
Soil respiratory quotient determined via barometric process separation combined with nitrogen-15 labeling
(Soil Science Society of America, 2004)
The barometric process separation (BaPS) and ¹⁵N dilution techniques were used to determine gross nitrification rates on the same soil cores from an old grassland soil. The BaPS-technique separates the O₂ consumption into ...
A wood based low-temperature biochar captures NH₃⁻N generated from ruminant urine-N, retaining its bioavailability
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2012-04)
Aims: Ammonia (NH₃) can be volatilised from the soil surface following the surface application of nitrogenous fertilisers or ruminant urine deposition. The volatilisation of NH₃ is of agronomic and environmental concern, ...
Biochar adsorbed ammonia is bioavailable
(Springer Netherlands, under the auspices of the Royal Netherlands Society of Agricultural Science, 2012-01)
Biochar is produced as a by-product of the low temperature pyrolysis of biomass during bioenergy extraction and its incorporation into soil is of global interest as a potential carbon sequestration tool. Biochar influences ...
Effect of soil moisture and bovine urine on microbial stress
(Elsevier on behalf of Urban and Fischer, 2012)
While many studies have examined the cycling of urinary nutrients, few have focused on the effects ruminant urine might have on the soil microbial community. Urine application can cause microbial communities to become ...
Real-time, high-resolution quantitative measurement of multiple soil gas emissions : selected ion flow tube mass spectrometry
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
A new technique is presented for the rapid, high-resolution identification and quantification of multiple trace gases above soils, at concentrations down to 0.01 µL L⁻¹ (10 ppb). The technique, selected ion flow tube mass ...
Accounting for the utilization of a N₂O mitigation tool in the IPCC inventory methodology for agricultural soils
(Springer Netherlands, 2007)
In this study we review recent studies
where dicyandiamide was used as a nitrification inhibitor to reduce both N₂O emissions from urine patches and nitrate leaching from pasture systems, and which led to the development ...
Nitrous oxide emissions from in situ deposition of ¹⁵N-labeled ryegrass litter in a pasture soil
(Crop Science Society of America, Soil Science Society of America and American Society of Agronomy, 2013-03)
During pasture grazing, freshly harvested herbage (litterfall) is dropped onto soils from the mouths of dairy cattle, potentially inducing nitrous oxide (N₂O) emissions. Although the Intergovernmental Panel on Climate ...
