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.

Digital soil mapping aids soil use understanding

Soil scientists have reached a new milestone, digitally mapping more than 8 million hectares of New Zealand soils.

"Our latest progress shows the national S-map soil mapping programme has now covered 30% of the New Zealand land area," says Manaaki Whenua - Landcare Research Soil Scientist Sam Carrick.

More than one-quarter of New Zealand's GDP is directly dependent on our soil, which underpins both the productivity and health of New Zealand's land and freshwater ecosystems.

Soils range in quality and texture and Manaaki Whenua scientists have been researching, mapping, assessing and recording New Zealand's soils to measure its condition, identify risks and share this information with a wide range of people, including farmers, community groups, and councils, using a digital information system called S-map online.

"S-map online started in the mid-2000s when there was a push to digitise paper soil mapping records and help those using our soil understand it better by accessing information on historic and new soil records for the wide variety of New Zealand soils," says Sam.

"The primary focus up to now has been mapping land with high production potential that is most likely to have the most intensive land use pressures. S-map has managed to map half of this land," he says.

Recognising the national importance of quality soil information, the Fertiliser Association has combined with several regional councils to support the improvement of soil water data that S-map supplies to end-users - or which are used in models such as Overseer. Over the last 25 years, soil water measurements have been completed at many sites.

"This data has largely lain forgotten in old reports and records, but in the past year we've been uploading data from 262 legacy sites into the National Soil Data Repository, recovering over $2.6M of previous public investment that is of critical importance to today's decision-makers," says Sam.

By June the number of sites with soil water data in the Repository will have more than doubled to around 700.

"This will help significantly improve the models that supply soil information in S-map."

Over the next two years the NextGen programme will be carrying out more new measurements to fill data gaps on key soils such as the pumice soils in the Waikato region, as well as further sites in the Waikato, Hawkes Bay and Wellington regions. Watch out for further improvements over the next few years.

The Fertiliser Association of New Zealand and Dairy NZ funded development of the Nutrient Management Adviser Certification Programme (NMACP). This industry-wide certification aims to ensure that advisers have the learning, experience and capability to give sound nutrient advice.
