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.

Nitrogen leaching under grazed lucerne

Malcolm McLeod, Manaaki Whenua - Landcare Research
Completed March 2020

Introduction

Lake Taupō Protection Trust (LTPT), the Sustainable Farming Fund (SFF), Pāmu, Fertiliser Association of New Zealand, and Waikato Regional Council funded a field trial on N-leaching under grazed lucerne on a Taupo Lake Care member's farm. The project objective was to use lysimeters to quantify nitrogen leaching due to livestock urine from autumn-grazed lucerne or ryegrass/clover pasture.

Grazing was simulated by the application in autumn of ewe lamb or cow urine collected from animals whose diet included lucerne. Results showed that a single autumn urine application (simulated grazing) significantly increased N leaching compared to controls, but no significant differences were found between pasture or lucerne vegetation. When expressed at the paddock scale, assuming urine patches cover 3% of the paddock during a single grazing, the three-year average nitrogen leaching loss from the autumn grazing was approximately 2 kg TN/ha/yr under cow grazed lucerne and approximately 3 kg TN/ha/yr under cow grazed pasture. Controls (no grazing) showed leaching losses of approximately 1 and 2 kg TN/ha/yr for lucerne and pasture respectively.

"Studies like these are critical to understanding the nutrient flows in different farm systems," says Greg Sneath, Executive Manager, Fertiliser Association of New Zealand.

"It helps provide the information needed for building the tools for management and mitigation of nitrogen losses in productive farm systems."

The 2022 AgriTechNZ Baseline of Digital Adoption in Primary Industries report was released in August.

Created as part of a study by AgriTechNZ and insights partner Research First, the report was co-designed with partners The Fertiliser Association of New Zealand, Zespri, The Foundation of Arable Research and DairyNZ. It was also supported by the Ministry for Primary Industries as part of the Sustainable Food and Fibre Futures initiative (SFFF).

The 60-page report looks at digital adoption, including key drivers and barriers across the dairy, horticulture, arable and beef/sheep sectors.

The British Society of Soil Science has published a research article in the Soil Use and Management Journal detailing the latest analysed data from the long-running Winchmore Fertiliser Trial in Canterbury.

The paper was written by Driss Touhami of the Faculty of Agriculture and Life Sciences, Lincoln University. Touhami is also a member of the AgrioBioSciences Program, Mohammed VI Polytechnic University in Ben Guerir, Morocco.

The paper, titled "Effects of long-term phosphorus fertilizer inputs and seasonal conditions on organic soil phosphorus cycling under grazed pasture", was co-authored by Leo Condron Richard McDowell and Ray Moss.  The report can be viewed here.
