Feeding the world’s growing population

New Zealand’s reputation as a quality food producer is growing.

Optimising food production

Over the next 50 years farmers around the world will need to produce more food than has been grown over the past 10,000 years.

Best use from a limited resource

Fertiliser helps farmers produce food efficiently by replenishing the soil. But fertiliser needs to be used responsibly.

Responsible and sustainable nutrient management

The Fertiliser Association invests in research and tools to ensure farm profitability while minimising nutrient losses to the environment.

The Fertiliser Association of New Zealand promotes and encourages responsible and scientifically-based nutrient management.

Assessing the effectiveness of applying nitrification inhibitor in stockcamps for mitigating nitrogen loss from grazed pastures

AgResearch (Grasslands, Palmerston North) – Frank Li and K Betteridge
Concluded June 2013


Application of the nitrification inhibitor DCD is a promising technology for reducing N loss from grazed pastures, but its application over the whole farm may not be economically justified, especially on hills that require aerial application. Critical source areas (CSAs), such as stock camps, represent the areas of highest urinary-N deposition, highest N loss risk, and potential highest efficacy of DCD application in mitigating N loss.

This work was part of a larger Sustainable Farming Fund Project.

Dairy farmers milking cows on a farm area of more than 20 hectares are required to record synthetic nitrogen use on their dairy platform land, including a zero-kg record if no synthetic nitrogen is used. The regulations require data to be submitted by 31 July each year for the preceding year ended 30 June.
