Northern Adelaide Plains horticulture region

The Northern Adelaide Plains (NAP) is a key horticulture region of South Australia that lies immediately north of the Adelaide metropolitan area.

The region produces approximately 198,000 tonnes of fresh produce, generating around 20% of the state’s horticulture production by volume and 33% by value, with a farm gate value of $317 million.

The area is renowned for growing premium quality vegetables including tomatoes, cucumbers, capsicums, onions and potatoes, among others.

Horticulture on the NAP covers 5,500 hectares. Of this, more than 1,100 hectares is dedicated to covered cropping – such as poly houses – making the NAP the largest covered cropping region in Australia.

The region contains a mix of horticultural land uses including;

  • broad-acre field vegetable cropping
  • tree orchards
  • high-technology climate controlled hydroponic systems and
  • medium and low-technology poly and shade houses.

In addition, almost half of South Australia’s vegetable industry workers are employed on the NAP.

Global leaders in food production

A leader in intensive food production, the NAP region is vital for the prosperity of the state’s horticulture sector.

The South Australian Government is committed to driving long-term growth in production, investment and skills in the region. This is being facilitated through the development of a range of initiatives, programs and education resources for producers.

Northern Adelaide Plains Agribusiness Initiative

To support agribusiness growth in the NAP region and to support the Government’s Growth State: our plan for prosperity, the South Australian Government has implemented initiatives such as the Northern Adelaide Plains Agribusiness Initiative (NAPAI) that includes enabling infrastructure such as access to water, and improving export market growth through improved biosecurity arrangements.

Northern Adelaide Irrigation Scheme

The State Government is also growing the capacity of the Northern Adelaide Plains region through increased access to water resources. The Northern Adelaide Irrigation Scheme (NAIS) will ensure the long-term viability of its horticulture industry and the social and economic future of its communities.

Information for producers

Clean your farm program

To help growers implement best practice on-farm biosecurity on the Northern Adelaide Plains, PIRSA has partnered with AUSVEG SA and the Department for Environment and Water to establish the ‘Clean Your Farm’ initiative.

Clean Your Farm aims to raise awareness of key sources of risk for vegetable diseases and pests and help growers better protect their produce and ultimately their income. The initiative focuses on two key areas:

  • how equipment and visitors can spread disease
  • bad bugs live in weeds.

How to reduce risk and manage pests

Almost anything that can be moved on or off a property can also transport pests or diseases. This is why implementing good biosecurity practices is so important. You can help protect your farm by:

  • understanding how threats can come into farm environments
  • what can be done to reduce risk.

The Essentials Toolkit from Farm Biosecurity outlines quick and simple measures that can be built into everyday on-farm practice that will help protect your farm and your future.

The toolkit covers recommended practices in relation to:

  • farm inputs
  • farm outputs
  • people, vehicles and equipment
  • production practices
  • feral animals and weeds
  • train, plan and record

Pests to look out for include:
