Why?
Nitrate Leaching from agricultural
land has become a greater problem in recent years, particularly with intensification in agricultural
production, with a growing rise in the use of nitrogen fertilizers and the application of slurry.
Detail
- This
report reviews research conducted in New Zealand, to examine the usefulness of Nitrification Inhibitors
for reducing nitrate leaching from grazed grassland
- Also examines the potential
application of this
research for Northern Ireland
Result
- Nitrification
Inhibitors can be effective, but this varies with time
- Previous studies have been
conducted on a small-scale experimental basis and more data are required from field studies
- Factors
limiting the use of Nitrification Inhibitors include cost and period of time for which their application
remains viable (3 weeks)
- Good management practice may be as effective as Nitrification
Inhibitors in reducing nitrate leaching
