Result from nitrification trials

12:49 pm on 24 February 2012

Three years of trials have confirmed that nitrification inhibitors can help farmers to reduce the environmental impacts of pastoral farming.

Research carried out in Waikato, Manawatu, Canterbury and South Otago measured the effectiveness of the active ingredient in the ntriofication inhibitor, Eco-N, dicyandiamide.

Pastoral Greenhouse Gas Research Consortium manager Mark Aspin, says the trials confirmed a significant impact on reducing nitrous oxide emissions and nitrogen leaching from urine in pasture, but less of an impact boosting pasture production.

While nitrification inhibitors are an effective tool in reducing green house gas emissions from livestock, Mr Aspin says research into reducing methane gas is ongoing and there have been no breakthroughs yet.
