Irrigation New Zealand

Water sources for irrigation can be at a higher, the same, or lower elevation than the area to be irrigated. Water from a higher elevation, when distributed through a closed conduit (a pipe), possesses potential energy. This may enable water to be supplied for irrigation at the required pressure without adding external power (pumping). However, for similar or lower elevations the water will have a zero or negative potential energy. This requires the addition of energy so the water can be supplied at pressure. A pump is needed to do this. Put simply, a pump is a machine that transfers mechanical energy into pressure and velocity energy in flowing water.

The INZ Pumping and Hydraulic Resource Book provides an overview of pumping and hydraulic considerations for successful irrigation.


Wednesday 11 April–12 April

10:00 am - 17:00 pm

Join us for a two day Fertigation Master Class

When: 11th and 12th April 2018

Where: Lincoln Event Centre

Cost: $650 +GST

Places are limited so get in early to avoid disappointment.

The outcome of the class is to produce a resource that will provide irrigators with clear information for successful fertigation, including costs and benefits, good management practice knowledge resources and related training opportunities.

It will also enable irrigators and their service industries to inform and achieve any future regulations around fertigation equipment and practice.

The master class will help to unlock the future potential of fertigation in NZ through providing answers to the following questions –

  1. What are the costs and benefits of fertigation?
  2. What are the equipment options for fertigation and to which scenarios are they best applied?
  3. What does ‘good practice’ design, installation and management look like?

The programme involves presentations on each topic followed by discussion and agreement that these are industry accepted standards. There will be a field trip on the afternoon of day 1 as well as a dinner on the Wednesday night. Full programme will be released soon….

The price for the master class is $650 + GST

Notice of withdrawal: 7 days – 50% registration refunded or transferable to another person, 3 days – no refund – transferable to another person
