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. ...
Effectiveness of the nitrification inhibitor dicyandiamide and biochar to reduce nitrous oxide emissions
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2016)
Animal urine from grazing animals is responsible for the majority of New Zealand’s nitrous oxide (N₂O) emissions. A field lysimeter study was conducted to determine the ability of the combination of the nitrification ...
Effect of different land use and land use change on ammonia oxidiser abundance and N₂O emissions
(Elsevier, 2016-05)
In recent years, there has been a major expansion of dairy farming in New Zealand, largely as a result of land use change from forestry and sheep farming to dairy farming. Possible impacts of different land uses and land ...
Comparison of dicyandiamide and biochar for reducing nitrate leaching under winter forage grazing in Canterbury, New Zealand
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2015)
The presence of nitrate (NO₃⁻) in a water body can contribute to surface water eutrophication and can be harmful to the health of humans. The objective of this study was to determine suitable mitigation options for reducing ...
Simulated animal trampling of a free-draining stony soil stimulated denitrifier growth and increased nitrous oxide emissions
(Wiley on behalf of the British Society of Soil Science, 2016-09)
Winter forage grazing systems in New Zealand cause compaction of soil by grazing animals, especially when the soil is wet. However, there is little information on the effects of animal trampling on denitrifiers in soil, ...
Effect of soil aggregate size and dicyandiamide on N₂O emissions and ammonia oxidizer abundance in a grazed pasture soil
(Wiley on behalf of the British Society of Soil Science, 2014-06)
Nitrous oxide (N₂O) is a potent greenhouse gas, which is mainly produced from agricultural soils. Ammonia oxidation is the rate-determining step in N₂O production, and the process is carried out by ammonia oxidizers, ...
Ammonia oxidising populations and relationships with N₂O emissions in three New Zealand soils
(Taylor & Francis, 2014-07-15)
© 2014 The Royal Society of New Zealand.Nitrous oxide (N₂O) emissions from intensively grazed pasture systems contribute significantly to total greenhouse gases. A series of field-plot experiments were conducted at three ...
