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.

Seventy years of data from the world's longest grazed and irrigated pasture trials

New publication showcasing Seventy years of data from the world's longest grazed and irrigated pasture trials, provides an invaluable data resource for the scientific community.

The publication, titled Seventy years of data from the world's longest grazed and irrigated pasture trials, has recently been published in on-line journal Scientific Data. In it, lead author Dr Richard McDowell, Principal Scientist at AgResearch, and Professor at Lincoln Science Centre, Faculty of Agriculture and Life Sciences at Lincoln University, showcases resources and data that have been assimilated since 1950 at the Winchmore long-term fertiliser and irrigation trials located on the Canterbury plains.

This new publication alerts the scientific community to the data that has been generated by the world's longest running sheep grazed fertiliser and irrigation trials under consistent stable conditions. It addresses the history of the research site, the nature and breadth of data that has been assimilated over the years, and how interested researchers may make best use of this unique resource. There are roughly 96,000 records of soil chemistry and physical data, plus information on pasture yield and botanical composition.

The trial site was initially established by the New Zealand government and has been managed by AgResearch. Scientific investigation has been conducted here ever since. A wide range of organisations have had access to parts of the site, and while protecting the integrity of long-term treatments, the information and data outlined in this publication will encourage greater use and benefit from this invaluable data resource.

Grazed pastures are the most widespread land-use globally, and the research at Winchmore has local, national and international relevance. While initially established to evaluate pasture response to phosphate fertiliser and irrigation treatments, the experiments have provided additional invaluable information and resources to address topics as diverse as:

  • improvements in sheep, dairy and deer production
  • the efficacy and scheduling of irrigation
  • improvements in pasture and crop production
  • agronomic and environmental soil and water research
  • entomology, soil contaminants and impacts on soil carbon.

"The consistent treatments provided by this site have enabled examination of issues and impacts that would not have been foreseen 70 years ago when the site was first established," says Vera Power, Chief Executive, Fertiliser Association of New Zealand.

"The Fertiliser Association of New Zealand has taken a long-term lease of this land to ensure that the grazed phosphate fertiliser trial data will remain available for scientific research for decades to come, even though the long-term irrigation trial has been discontinued."

FANZ has made a submission to the Ministry for the Environment on Te hau mārohi ki anamata - Transitioning to a low-emissions and climate-resilient future

The primary sector has a key role to play in helping achieve global reductions in greenhouse gas emissions while maintaining food security. This requires low-emission production systems, with increased efficiencies and the use of new mitigation technologies. 

Investment in the development and adoption of new technologies requires a clear regulatory pathway to market. We will need to work internationally with trading nations and also locally with existing qualified networks within the agricultural community for the extension and adoption of new mitigations.
