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.

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

Responsible and sustainable nutrient management

Overseer

Overseer is an agricultural management tool which helps farmers and growers make better farm management decisions to improve their farm's environmental sustainability and productivity.

Much like a financial budget, a nutrient budget tells you how much is coming in and how much is going out and to where. By using Overseer, you can see:

  • how efficiently nutrients are being used on a farm
  • expected nutrient and greenhouse gas losses to the environment
  • the likely impacts of changes in farm management practices or farm systems.

Overseer allows farmers and their advisers to test the potential impacts of different approaches before investing time or resources in big changes.

The tool is managed by Overseer Ltd, which was established as a not-for-profit organisation to administer the software. The company is jointly owned by the Fertiliser Association of New Zealand, Ministry for Primary Industries (MPI) and AgResearch Limited.
