Nitrogen through your pivot, not a truck.

  • Less leaching
  • Proof of placement
  • No trucks

We design and install systems that apply liquid nitrogen through your centre pivot. Less leaching, a record of every application, no trucks on your paddocks.

Fertigation is applying liquid fertiliser through your irrigation system. Your pivot already covers every hectare it waters. We add a measured dose of liquid nitrogen to that water, so it goes on little and often, exactly where the water goes.

    Graeme's experience with fertigation

Why fertigation

What it does for your farm.

Put your nitrogen through the water you're already applying: little and often, exactly where the pivot goes, with a record of every application.

  • Water droplets on a blade of pasture grass

    Less leaching, easier compliance.

    Smaller, split applications the grass can use, with proof of where and when every application went. It can be incorporated in Overseer.

    Lower costs.

    Less fertiliser, no spreading runs, and a short payback on set-up costs.

  • Close-up of tall, green pasture grass

    Steadier grass.

    More even growth makes grazing easier to manage. One client saw more clover.

  • A dairy herd grazing a green paddock with mountains behind

    No trucks on the paddock.

    No compaction, no gates left open.

From first visit to first application.

Step 1

We look at how your farm runs.

Farm size, irrigation type, water source, volumes and flow rates, the technology you use and who manages fertiliser now.

Step 2

We design around your irrigation.

A system that fits how your pivots run day to day, and what you're changing this season or next.

Step 3

We install, commission and train.

Your whole team learns the system on farm, with written instructions for new staff and delivery drivers.

Step 4

We back it.

Every system comes with a service agreement. Running it should be as simple as booking a truck.

  • 100 L of liquid N
  • 100,000 L of water
  • 1:1000 About this dilution

Safe for your pivots.

100 litres of liquid N (19 units of N) mixed into 100,000 litres of water at 10 mm per hectare is a dilution of about 1:1000.

For us, the proof is in the pudding.

Andy and Allan Grant started with one fertigation system on one farm in 2015. Once they'd run it, they asked for a second on their other dairy farm. Both systems are still running.

No trucks are needed to apply nitrogen to the farm, which reduces soil compaction and no gates are left open.

Questions farmers ask

No. The dose is tiny compared with the water: about 1:1000.

We start by looking at your irrigation type, water source and flow rates, then design to suit.

Your team, after on-farm training and with written instructions. It's designed to be as simple as booking a truck.

Yes. The system gives you proof of placement and application records.

It depends on your farm. Set-up costs pay back quickly through fertiliser and spreading savings; book an assessment and Graeme will work through the numbers for your farm.
