Fertigation Tanks
Polymaster’s fertigation tanks are built for vineyards, orchards, and any fertiliser dosing application, mixing and distributing liquid fertiliser through the irrigation system. Each tank uses a venturi fitout for safe mixing with no moving parts, and a self-draining base so nothing is left behind when the tank is emptied.
Available in 2,000L, 5,000L and 9,000L capacities, both manufactured in Australia and resistant to most fertilisers and trace elements.

SAFE MIXING
Built for Effective, Self-Draining Mixing
Each tank mixes fertiliser through a recirculation pump paired with a venturi fitout, so there are no moving parts inside the tank itself. The base is self-draining, so there is no waste left behind when the tank is emptied between mixes. Every tank is resistant to most fertilisers and trace elements.
The pump shown in product imagery is for illustration purposes only and is ordered separately. See Section 6 for a compatible pump option.
CONSTRUCTION AND SETUP
Built for Straightforward Installation
Every tank base is moulded to allow the sump pipe to be fitted before the tank is installed on its base. Current sump pipes use a quick-fit connection for easy pipework connection, replacing the older uni-seal method. Water level controllers are available to suit.
Every tank is manufactured in one piece, with no joins, seams, or part lines, and features double-strength UV+ resin to protect the tank for the long term in the Australian climate.

Storage and Tanks That Work Alongside Fertigation
A fertigation system meters product into your irrigation, but it still needs a reservoir to draw from, and the same polyethylene tanks earn their keep elsewhere on the property. Here’s what most growers pair with it.
Self-Draining Liquid Fertiliser Tanks
A clean supply source for the fertigation line. The sloped base clears out completely, so there is no settled residue getting drawn into your dosing gear and throwing off application rates.

Flat Bottom Liquid Fertiliser Tanks
The bulk reservoir a fertigation setup runs off when you are injecting steadily across a season. Maximum holding volume for the footprint, so you refill less often during peak application.

Aquaculture Tanks
Polyethylene tanks built for holding water and aquatic stock rather than fertiliser. Same durable construction, different job – relevant if your operation runs aquaculture alongside cropping.

FAQs
Frequently Asked Questions
What is a fertigation tank?
A fertigation tank mixes and stores liquid fertiliser before it is fed through an irrigation system, so crops get nutrients directly through drip or sprinkler lines rather than a separate application. Polymaster’s fertigation tanks use a venturi fitout for mixing and a self-draining base, available in 2,000L, 5,000L and 9,000L capacities.
How does a fertigation tank work?
The tank uses a recirculation pump paired with a venturi fitout to blend fertiliser, with no moving parts inside the tank itself. Once mixed, the fertiliser is drawn out through the base and fed into the irrigation system. The self-draining base means the tank empties completely when you are done, so there is no residue left to affect the next mix.
What is the purpose of fertigation?
Fertigation lets you apply fertiliser through the same irrigation system already watering your vineyard, orchard, or crop, so nutrients go directly to the root zone with the water. It is a more targeted way to feed plants than broadcasting fertiliser separately, and it works well with drip or sprinkler irrigation.
What are the common problems with fertigation?
The most common issues are clogged lines from undissolved fertiliser, uneven mixing that leaves some areas over- or under-fertilised, and residue left behind in the tank that contaminates the next mix. Polymaster’s venturi fitout is built to mix without moving parts, and the self-draining base avoids the residue problem, which is the main reason to choose a purpose-built tank over adapting a general storage tank.
What is the best time to apply fertigation?
This depends on your crop, growth stage, and fertiliser type, so it is best worked out with an agronomist or your existing irrigation schedule. What the tank itself needs to do is mix and deliver fertiliser reliably whenever you are ready to apply it.
Does the tank come with a pump?
No. The pump shown in product images is for illustration purposes only and is ordered separately. The Liquid Chemical Transfer Pump 6.5HP Honda (HTP750VR) is built for use with a Venturi system and pairs directly with this range.
Is the lid included with the tank?
No, the lid is sold separately and suits the 2,000L tank. It is available in dark or light green, specify your preference when ordering.
