Nevada Fertigator™

An affordable, portable effluent irrigation solution
Trusted for Safety and Reliability

Nevada Fertigator™

Your Portable Effluent Irrigation Solution

If you need to spread dairy effluent over a large area with a controlled application rate, the Nevada Fertigator™ is for you! 

The Fertigator™ is a portable effluent irrigation solution, manufactured in New Zealand especially for local farming conditions.  Spreading effluent straight from the pond or sump, you can say goodbye to common irrigator issues like run-off, ponding, and groundwater contamination. Simply connect with your pump and drag hose, and away you go!

Hook up the optional tow kit to your farm bike or tractor and the Fertigators™ are easily movable, making them perfect for any size farm. With a wide 700mm diameter base for stability, the Fertigator™ will glide over both flat land and steeper areas without toppling over, and will always maintain consistent spread.
Nevada Fertigator Features

Nevada Fertigators™ suit both small and large pumps, and can be used in conjunction with a travelling irrigator if required. With 10mm, 12mm, or 14mm nozzles, blockages are minimised, allowing you to get the job done more efficiently. What’s more, the gun is made from metal, not plastic, for long term reliability.
  • Low application rate.
  • 10mm, 12mm, or 14mm nozzles minimise blockages.
  • Gun constructed from metal, not plastic.
  • 50m of drag hose between units (not included).
  • Up to 1500m² coverage (at 45psi).
  • Common 2 inch camlock fittings.
  • Can be used with both small and large pumps.
  • Wide 700mm diameter base for stability.
  • Optional tow kit available (for towing with the farm bike)

In-Line Effluent Filters (Recommended)

In-Line Effluent Filters are designed to eliminate debris that create blockages in irrigation nozzles.  They’re really simple, with liquid flowing through the screen inside the filters body.  All you need to do is open the top of the filter, remove the filtering screen, get rid of the trapped debris, replace the cleaned screen and reassemble the filter.  A real tidy operation!

Remote valve switch (Optional)

The remote valve switch
lets you switch between one irrigation line to another (or bypass back to the pond) without turning off the pump.  This is made possible with use of a soft close switching system eliminating any potential pressure spikes. It’s so simple - just activate it from your mobile phone!
