Irrigated crops in South Australia

Fertigation Systems

Feed your plants through your irrigation system. Accurate, even nutrient delivery for orchards, vineyards, market gardens, nurseries and productive home gardens.

Feeding through the irrigation

Water and nutrients in the same place, at the same time

Fertigation injects soluble fertiliser into the irrigation water, so nutrients reach the root zone in small, regular doses instead of a few large broadcast applications. Plants can use more of what you apply, less is lost to run-off and leaching, and nobody has to spread fertiliser by hand.

We design and install fertigation systems sized to your irrigation and the way you want to feed, from a simple venturi injector on a home veggie garden to dosing pumps and dedicated tanks on orchards around Balhannah and vineyards around Woodside.

Every fertigation setup includes appropriate backflow protection and filtration, so fertiliser cannot get back into your water supply and emitters stay clear. Fertigation works best on a well-designed drip system, so if yours needs attention, start with our installation and design service.

Fertigation options

Choosing the right setup

Venturi injectors

Simple, low-cost injection with no moving parts. Well suited to smaller systems and home food gardens.

Proportional dosing pumps

Water-powered injectors that dose at a set ratio regardless of flow, for consistent rates across zones.

Electric injection pumps

Precise, controllable dosing for larger systems, able to be linked to the irrigation controller.

Tanks and mixing

Correctly sized tanks, mixing and plumbing for preparing and holding fertiliser solutions.

Backflow and safety

Backflow prevention, check valves and isolation so chemicals can only flow one way.

Filtration and flushing

Filtration after the injection point and a flushing routine so drippers do not block with residue.

FAQs

Common questions

What fertilisers can go through a fertigation system?

Water-soluble fertilisers made for fertigation. Some products react with each other or with hard or iron-rich water and can block emitters, so we talk through what you plan to use. For crop nutrition programs we are happy to work alongside your agronomist.

Is fertigation worth it for a home garden?

For productive gardens such as veggie patches, fruit trees and permaculture plots it can be. A simple injector is inexpensive and makes regular liquid feeding effortless.

Can fertigation be added to my existing system?

Usually, yes. We assess the system's flow, filtration and backflow protection first, then fit the injector in the right spot.
