Fertiliser Mixing Station Benefits: Save Time and Cut Fertiliser Costs

Key takeaways

• A fertiliser mixing station dissolves soluble fertiliser straights automatically, removing the need for manual stirring.

• Automated mixing and in-line filtration remove the risk of undissolved product blocking sprayer nozzles.

• Mixing your own straights costs a fraction of buying ready-to-mix liquid concentrate.

• One real-world example showed a saving of around 30 minutes per tank fill.

• A mixing station lets one tank fill and mix unattended while a previous batch is already being sprayed.

How much time does your team lose mixing soluble fertiliser by hand? And how many sprayer blockages come from particles of undissolved product? 

A fertiliser mixing station solves both problems by automating agitation and filtering the mix before it reaches the sprayer, meaning faster tank fills, lower product cost, and far fewer blockages. 

This article sets out what a fertiliser mixing station is, its main advantages, what it costs to run, and what to check before buying one.

 

What is a fertiliser mixing station?

A fertiliser mixing station is a tank-based unit that automatically dissolves soluble fertilisers and turf treatments in water before transfer to a sprayer. 

It replaces manual stirring with automated agitation and filtration, producing a consistent, blockage-free solution.

"Soluble straights" means individual fertiliser products such as NPK (nitrogen, phosphorus and potassium), sulphate of iron, sulphate of ammonia, or urea, bought as a powder or granule rather than a pre-mixed liquid (Penn State Extension). These straights need to be fully dissolved before they go through a sprayer, and that is the job a fertiliser mixing station does using automated agitation instead of hand-stirring.

 

Why does manual fertiliser mixing cause problems for turf teams?

Mixing soluble fertiliser by hand is one of the slowest, most error-prone jobs in a spray programme. Dissolving granules in the strainer basket while filling with a hosepipe takes time away from spraying itself, and it is easy to under-mix without realising it.

Undissolved fertiliser is the main cause of sprayer nozzle blockages, which leave stripes of untreated turf and require you to stop work altogether until cleared.

 

5 advantages of using a fertiliser mixing station

A fertiliser mixing station saves time, cuts product cost, and prevents the sprayer blockages that come with hand-mixing. The main advantages are:

1. Faster tank fills: Automated agitation and a high-performance pump mix and transfer a full tank in just minutes, rather than the time it takes to fill the sprayer with a hosepipe.  This is equally beneficial when using soluble granules or liquid concentrate.

2. Lower product cost: Mixing your own soluble straights costs a fraction of buying ready-mixed liquid concentrate.

3. Fewer sprayer blockages: In-line filtration removes undissolved particles before the mix reaches the sprayer, protecting nozzles from clogging.

4. No downtime between tanks: One tank can fill and mix unattended while the previous batch is already out being sprayed.

5. Less wear on equipment: Dissolving fertiliser in the mixing station avoids wear on the sprayer pump over time.

 

Data & benchmarks

• A 1,200-litre fertiliser mixing station tank mixes fully using cold water, with no need to heat water first.

• At JCB Golf & Country Club, spray technician Dan Waring reported the Mega-Mix was "saving us about half an hour per tank" and that the team could be "in and out in about five minutes" when filling (GreenTek, 2025).

• GreenTek's fertiliser mixing equipment carries a 5-year warranty and a 12-month money-back guarantee.

 

How much does a fertiliser mixing station cost, and what's the return?

The main financial case for a fertiliser mixing station is the saving on product: mixing your own straights costs a fraction of buying ready-to-mix liquid concentrate. Time saved on every tank fill adds up further still.

Exact pricing is usually confirmed directly with your local dealer, since GreenTek sells through a dealer network rather than listing prices online. (Based on a UK-based golf or sportsground team assessing cost over a typical playing season.)

A fertiliser mixing station is a capital purchase, and it won't pay off on every site. If your team only prepares a handful of tanks each season, the savings may not offset the unit cost; it makes the strongest case for teams regularly spraying larger areas such as golf fairways or multiple sports pitches.

To estimate your own return, use this formula: (Cost per litre from concentrate, minus cost per litre from solubles) x litres used per spray day x spray days per year, PLUS (time saved per spray day x spray days per year  × hourly labour cost) 

Check this annual saving against the unit price to see how soon it will have paid for itself and be generating you a profit.

 

How does a fertiliser mixing station compare to mixing by hand or using liquid concentrate?

A fertiliser mixing station combines the low product cost of mixing your own straights with the consistency of automated preparation, sitting between hand-mixing and liquid concentrate on both cost and effort.

Method	Product cost	Time per tank	Blockage risk
Manual mixing (straights, by hand)	Low	Slow	High – incomplete dissolving is common
Liquid concentrate	High	Fast	Low
Fertiliser mixing station (straights, automated)	Low	Fast	Low – in-line filtration removes undissolved particles

 

5 things to look for in a fertiliser mixing station

The key features to check before buying a fertiliser mixing station are tank capacity, agitation method, and filtration.

1. Tank capacity relative to your sprayer: The tank should hold enough to fill your sprayer in one go.

2. Automated fill and shut-off: Lets the tank fill and mix unattended while you focus on other jobs.

3. Dual agitation: Ensures the product dissolves completely, not just at the surface.

4. In-line filtration: Protects the sprayer from blockages caused by undissolved particles.

5. Safe, easy loading: Features such as a fold-out step reduce the physical strain of loading product into the tank.

These criteria reflect standard features on stations such as GreenTek's Mega-Mix, so check each one against any model you're considering.  

A further consideration is whether to choose a petrol engine, or electric motor power.  A petrol engine gives the unit immediate portability.  For instance on a busy day of fairway spraying you may wish to position the mixer out on the course by an irrigation hydrant and do your mixing there to minimise travel distance for the sprayer.  On the other hand, if you wish to permanently run it inside a building, you will want to choose electric power to avoid engine fumes.

 

4 steps to set up and use a fertiliser mixing station

Using a fertiliser mixing station follows a simple four-step sequence: fill, agitate, filter, and transfer.

1. Fill and dose: Add water and the measured soluble fertiliser or straight to the tank.

2. Automated agitation: The dual agitation system breaks the product down until it's fully dissolved.

3. Filter and pump transfer: The mix passes through in-line filtration as it's pumped into the sprayer.

4. Refill during spraying: Start filling and mixing the next batch while the first batch is being sprayed out on the course.

This keeps one tank always ready while another is in use.

 

Fertiliser mixing station FAQs

Does a fertiliser mixing station work with all soluble fertilisers? 

Most handle common straights such as NPK, sulphate of iron, sulphate of ammonia, and urea. Check compatibility first.

Do I still need hot water to dissolve fertiliser straights? 

No. Automated agitation fully dissolves straights in cold water.

How much time does a fertiliser mixing station typically save per tank? 

This varies by site, but one golf clubs typically report saving around 30 minutes per tank fill.

Is a fertiliser mixing station compatible with my existing sprayer? 

Yes, the high volume transfer hose fills your sprayer through the same tank lid that you normally use with a hosepipe.

What maintenance does a fertiliser mixing station need? 

Routine checks on the filtration unit, plus flushing with clean water to keep the agitation system clear of residue between uses.

 

Fertiliser mixing station: the bottom line

A fertiliser mixing station gives you faster tank turnaround, lower product cost, and far fewer sprayer blockages than mixing by hand. Those are the exact problems hand-mixing soluble fertiliser creates: lost time, wasted product, and blocked nozzles that stop work altogether.

Compare tank capacity, filtration, and agitation systems against your own sprayer volume and season workload before choosing a model. GreenTek's Mega-Mix fertiliser mixing station is built around this exact set of features, backed by a 5-year warranty.

How to take action now

• Compare the cost per litre of mixing straights compared to your current liquid concentrate spend.

• Consider whether hand-mixing is costing you time through sprayer blockages.

• Review product size, specification, and warranty, before committing to a purchase.
