Effects of trampling of a wet dairy pasture soil on nitrous oxide emissions and the efficacy of a nitrification inhibitor, dicyandiamide.
(2012-01-31)
Nitrous oxide (N2O) emitted from urine patches in grazed dairy pastures is a
major contributor to the total greenhouse gas emissions in New Zealand. The
nitrification inhibitor dicyandiamide (DCD) has been shown to reduce ...
Inhibition of ammonia oxidisers to control nitrification rate under simulated winter dairy forage grazing conditions: An incubation study
(Fertilizer and Lime Research Centre, 2013)
The microbial process of nitrification plays a key role within the soil nitrogen cycle. Nitrification is the process where ammonia is oxidised to nitrite and then to nitrate and this process can have major negative ...
Effect of soil moisture status and animal treading on N₂O emissions and the effectiveness of a nitrification inhibitor mitigation technology
(New South Wales Department of Primary Industry, 2013-09)
Nitrous oxide (N₂O) is a potent greenhouse gas with a long term global warming potential about 298 times that of carbon dioxide (CO₂). In grazed grassland, most of the N₂O is emitted from nitrogen (N) excreted by the grazing ...
Ex-vivo cow rumen fluid fermentation: Changes in microbial populations and fermentation products with different forages
(Taylor & Francis, 2018-07-09)
This study investigated the effects of three forage treatments [herbal plantain (PL), ryegrass-white clover pasture (RW) and root crop fodder beet (FB)] on ex-vivo rumen fluid fermentations. Quantitative real-time Polymerase ...
Mitigation of nitrous oxide emissions using a nitrification inhibitor, alternative pasture and forage plants and gibberellic acid
(SLU, 2016-06)
In grazed pastures, nitrous oxide (N₂O), the potent greenhouse gas, is mostly emitted from animal excreta, particularly animal urine-N retuned to the soil during grazing. N₂O is produced in the soil through nitrification ...
Effect of plantain on nitrous oxide emissions and soil nitrification rate in pasture soil under a simulated urine patch in Canterbury, New Zealand
(Springer-Verlag, 2020-03-01)
Purpose: The aim of this research was to quantify the effect of plantain (Plantago lanceolata L.) on soil nitrification rate, functional gene abundance of soil ammonia oxidisers, and the concomitant effect on nitrous oxide ...
Effect of bovine urine and nitrification inhibitor DCD on ammonia-oxidising communities in three NZ soils as revealed by pyrosequencing of the amoA functional genes
(2016-11)
Ammonia oxidising microorganisms (AOM) oxidise ammonia to nitrite and play a crucial role in the nitrogen cycling in all environments. In intensively-grazed pastoral soils AOM have been implicated as the key microorganisms ...
Understanding the mechanisms for the lower nitrous oxide emissions from fodder beet urine compared with kale urine from dairy cows
(Springer Verlag, 2018-01)
Nitrous oxide (N₂O) is a potent greenhouse gas and is produced in the soil by nitrification and denitrification processes. Previous studies have reported apparent lower N₂O emissions from dairy cow urine from fodder beet ...
Effect of soil moisture status and a nitrification inhibitor, dicyandiamide, on ammonia oxidizer and denitrifier growth and nitrous oxide emissions in a grassland soil
(Elsevier, 2014-06)
Nitrous oxide (N₂O) is a potent greenhouse gas and is produced in the soil by nitrification and denitrification processes. These processes are catalysed by a number of key enzymes from microbial communities in the soil. ...
The response of ammonia-oxidizing microorganisms to trace metals and urine in two grassland soils in New Zealand
(Springer Verlag on behalf of EuCheMS Division of Chemistry and the Environment, 2017-01)
An incubation experiment was conducted to investigate the response of ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and the nitrification rate to the contamination of Cu, Zn, and Cd in two New Zealand ...
