The effect of animal trampling and DCD on ammonia oxidisers, nitrification, and nitrate leaching under simulated winter forage grazing conditions
(Springer Verlag (Germany), 2015-04)
Purpose: Dairy winter forage grazing on free-draining soils is a common practice within the Canterbury region of New Zealand. The high stocking rates involved and the associated deposition of urine onto wet soils during ...
Dicyandiamide (DCD) effect on nitrous oxide emissions, nitrate leaching and pasture yield in Canterbury, New Zealand
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2014)
© 2014 The Royal Society of New Zealand. A 3-year study was carried out in Canterbury, New Zealand, to determine the effect of a nitrification inhibitor dicyandiamide (DCD) on N₂O emissions, nitrate (NO₃⁻) leaching and ...
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 ...
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 ...
