The effectiveness of nitrification inhibitor technology to improve the sustainability of agriculture
(NZ Institute of Primary Industry Management (NZIPIM), 2009-12)
As reported widely in the general media and also in recent editions of Primary Industry Management, there is increasing recognition of the need to improve the sustainability of New Zealand agricultural systems. Fonterra’s ...
Using nitrogen : what is best practice?
(South Island Dairy Event (SIDE), 2005-06)
Feed shortages occur in spring because the rate of pasture growth is below the cow demand. Spring pasture growth rate is slow in the South Island because the soil temperature is low and the rate of nitrogen (N) supply from ...
Clean and green with 'eco-n'
(South Island Dairy Event (SIDE)., 2004-06)
Lincoln University and Ravensdown Fertiliser Co-operative have developed a new soil treatment technology, called 'eco-n' technology, that can reduce the environmental impacts of dairy farming and at the same time help ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
Nitrate leaching and nitrous oxide emissions related to bacteria and not to archaea in nitrogen rich grassland soils
(International Union of Soil Sciences, 2010-08)
The oxidation of ammonia (NH₃) to nitrate (NO₃⁻) is a key process in the global nitrogen (N) cycle which has major ecological and environmental implications both in influencing nitrous oxide (N₂O) emissions and NO₃⁻ leaching. ...
A synergistic mitigation technology for nitrate leaching and nitrous oxide emissions for pastoral agriculture
Report on a mitigation technology which is synergistic for the reduction of both NO3 leaching and N2O emissions and also for the improvement of pasture yield.
Effect of urine, potassium and dicyandiamide (DCD) application on pasture production from a free-draining Canterbury dairy pasture soil
(Fertiliser and Lime Research Centre, 2014)
A cut-and-carry trial was conducted on a low Quick-test potassium (QTK ≤ 4) Lismore soil during 2012-13 in Springston, Canterbury to test the responsiveness of a dairy pasture to urine, dicyandiamide (DCD) and potassium ...
Improved nitrogen management with eco-n nitrification inhibitor : an example of "growing for good"
(New Zealand Large Herds Association, 2005-04)
The recent report by the New Zealand Parliamentary Commissioner for the Environment, called "Growing for Good", highlighted the adverse impacts that nitrate leaching can have on water quality. It called for a 'redesigning ...
The effect of DCD on nitrogen losses from sheep urine patches applied to lysimeters in autumn
(New Zealand Grassland Association, 2010)
The intensification of modern pastoral agriculture has increased the risk of environmental degradation. The use of nitrification inhibitor technology has been shown to reduce nitrate (NO₃ ⁻) leaching losses and nitrous ...
Reducing nitrate leaching losses from a Taupo pumice soil using a nitrification inhibitor eco-n
(New Zealand Grassland Association, 2007-11)
The decline in water quality in Lake Taupo has been attributed to nitrogen (N) leaching from surrounding land areas. Pastoral agriculture has been identified as a significant contributor to this N transfer to the lake ...
