Impacts of long term copper exposure on abundance of nitrogen cycling genes and denitrification activity in pasture soils
(Elsevier BV, 2019-06-01)
Soils are the main source of nitrous oxide (N₂O) emissions, with 60–70% of global N₂O production due to the enhanced denitrification activity with elevated nitrogen (N) availability associated with agricultural intensification. ...
Influence of soil bulk density and matric potential on microbial dynamics, inorganic N transformations, N₂O and N₂ fluxes following urea deposition
(Elsevier Ltd., 2013-10)
Transformation of ruminant urine-nitrogen (N) can contribute to negative environmental outcomes such as nitrate leaching which leads to eutrophication of waterways and production of nitrous oxide (N₂O), a greenhouse gas. ...
Accumulation and distribution of phosphorus in the soil profile under fertilized grazed pasture
(Elsevier BV, 2017-02-15)
The fate of phosphorus originating from long-term fertilizer inputs in the soil profile is of great agronomic and environmental concern but remains poorly understood. Sequential fractionation was used to investigate ...
Mass balance assessment of phosphorus dynamics in a fertilizer trial with 57 years of superphosphate application under irrigated grazed pasture
(Springer Verlag, 2019-05)
Improving the efficiency of phosphorus (P) use is a major challenge for agricultural production and sustainability. Using a combination of new and historic data, a mass balance approach was employed to construct and discuss ...
Effect of nitrogen and waterlogging on denitrifier gene abundance, community structure and activity in the rhizosphere of wheat
(Oxford University Press and Blackwell Publishing Ltd on behalf of the Federation of European Microbiological Societies, 2013-03-01)
Microbial denitrification plays a key role in determining the availability of soil nitrogen (N) to plants. However, factors influencing the structure and function of denitrifier communities in the rhizosphere remain unclear. ...
