Author correction: Influence of soil moisture on codenitrification fluxes from a urea-affected pasture soil
(Nature Publishing Group, 2018-03-07)
Correction to: Scientific Reports https://doi.org/10.1038/s41598-017-02278-y, published online 19 May 2017.
This article contains an error in Figure 3, where the y-axis ‘DOC (μg g⁻¹ soil)’ is incorrectly labelled as ‘DOC ...
Phylogenetic and functional potential links pH and N₂O emissions in pasture soils
(Nature Publishing Group, 2016-10-26)
Denitrification is mediated by microbial, and physicochemical, processes leading to nitrogen loss via N₂O and N₂ emissions. Soil pH regulates the reduction of N₂O to N₂, however, it can also affect microbial community ...
Regulation of N₂O emissions from acid organic soil drained for agriculture
(Copernicus Publications on behalf of the European Geosciences Union, 2019-11-29)
Organic soils drained for crop production or grazing land are agroecosystems with potentially high but variable emissions of nitrous oxide (N₂O). The present study investigated the regulation of N₂O emissions in a raised ...
Density effects on soil-water characteristics, soil-gas diffusivity, and emissions of N₂O and N₂ from a re-packed pasture soil
(Soil Science Society of America, 2019-02)
Density-induced soil structural changes may potentially alter both soil total porosity and soil pore size distribution, and thus change the soil’s water retention characteristics, gas diffusion and transport properties, ...
Impact of nitrogen compounds on fungal and bacterial contributions to codenitrification in a pasture soil
(Springer Nature, 2019-09-16)
Ruminant urine patches on grazed grassland are a significant source of agricultural nitrous oxide (N₂O) emissions. Of the many biotic and abiotic N₂O production mechanisms initiated following urine-urea deposition, ...
Ammonium sorption and ammonia inhibition of nitrite-oxidizing bacteria explain contrasting soil N₂O production
(Macmillan Publishers Limited, part of Springer Nature and the Nature Publishing Group, 2015-07-16)
Better understanding of process controls over nitrous oxide (N₂O) production in urine-impacted 'hot spots' and fertilizer bands is needed to improve mitigation strategies and emission models. Following amendment with bovine ...
Nitrite accumulation and nitrogen gas production increase with decreasing temperature in urea-amended soils: Experiments and modeling
(Elsevier, 2020-03)
Nitrite (NO₂⁻) accumulation and associated production of nitric oxide (NO) and nitrous oxide (N₂O) gases in soils amended with nitrogen (N) fertilizers are well documented, but there remains a poor understanding of their ...
The potential of L. scoparium, K. robusta and P. radiata to mitigate N-losses in silvopastural systems
(Elsevier Ltd, 2017-06)
Silvopastoral systems aim to enhance economic, cultural and social principles by sustainably combining forest management with agriculture. In these typically high-nitrogen (N) environments, plant species selection can ...
High-resolution denitrification kinetics in pasture soils link N₂O emissions to pH, and denitrification to C mineralization
(Public Library of Science (PLoS), 2016-03-18)
Denitrification in pasture soils is mediated by microbial and physicochemical processes leading to nitrogen loss through the emission of N₂O and N₂. It is known that N₂O reduction to N₂ is impaired by low soil pH yet ...
