One carrier. Seven micronutrients. Fewer line items.

Hydrolysed soya protein and the amino-acid chelated micronutrients built on it — raw materials for fertiliser blenders and formulators, with published specifications, supplied and supported from East Perth.

One material doing three jobs

Soya Protein Hydrolysate is the material the rest of this range is built on, and the one worth understanding first. It is the chelating backbone in amino-acid micronutrient grades, keeping the metal in solution rather than letting it drop out. It is an organic-nitrogen source at 12% N, slower to release and less prone to leaching than mineral nitrogen. And its free amino acids carry a biostimulant claim — an upgrade to a recipe you already sell.

Three jobs, one line item. Buying them together takes SKUs out of the store rather than adding one, and it means the carrier under every micronutrient in your blend is the same material behaving the same way. It also works as a formulation aid, lifting foliar wetting and adhesion and holding metal in solution in the tank.

On that carrier sit seven amino-acid chelated micronutrients — zinc, iron, copper, manganese, cobalt, calcium and magnesium. Because they share a backbone, a blender can add or swap an element without re-testing how the base behaves.

Two chelated grades sit alongside them for the jobs the protein carrier is not built for: a six-element EDTA mixture where one input has to cover the lot, and EDDHA Fe-6 for high-pH calcareous ground, where an amino-acid chelated iron can let go and the iron precipitates out of reach. The chemistry behind that is here. .

The range

The carrier first, then the seven single-nutrient chelates built on it, then two chelated grades for the jobs a protein carrier is not built for. Every material carries a published sales specification and a certificate of analysis against it per batch.

Multi-micronutrient amino chelate blend

Spray-dried, supplying zinc, iron, manganese, copper, molybdenum and boron plus protein in a single input — one line item where a blender would otherwise dose six.

Glutamate diacetate (GLDA)

A biobased, readily biodegradable chelating agent that does EDTA's job — and lets a finished grade carry a biodegradable story to growers asking for one.

Trisiloxane organosilicone spreader

A super-spreading adjuvant for foliar grades — the coverage side of the same formulation, from the same supplier.

Molybdenum and boron chelates

Chelated on the same protein hydrolysate carrier as the rest of the range, so they behave consistently alongside it in a blend.

Take a trial quantity and blend it

Three materials make the useful first trial — the carrier that does three jobs, the chelates built on it, and a six-element mixture for a grade that has to cover the lot. Quantities to suit the trial; we will agree them with you.

01
Soya Protein Hydrolysate

Carrier, organic nitrogen and biostimulant claim in one material.

02
Amino-acid chelates

Seven single-nutrient chelates on that same carrier.

03
Chelated EDTA Mixture

Six elements in one input, where a grade has to cover the lot.

We can generate compatibility test data on request, so the trial answers how the materials behave in your blend rather than only what they are.

Where we supply

Blending raw materials, Australia-wide

We supply from East Perth to blenders and formulators across the country. Soil pH, carbonate and irrigation water differ sharply between these regions, and so does which micronutrient limits a blend — so we talk about the grades you sell and the ground they go out on, not a national average.

Western Australian wheatbelt

Sandy and gravelly soils from Geraldton through to Esperance, where low plant-available copper and zinc are long-recognised features and show at grain set rather than in the leaf.

Perth & the Swan Coastal Plain

Limestone sands and alkaline bore water high in bicarbonate — the ground where an amino-acid chelated iron can let go and EDDHA earns its place.

South Australian Mallee & Riverland

Calcareous soils under viticulture, citrus and almonds, with high-pH irrigation water pushing the same way.

Victorian Mallee & Sunraysia

Irrigated horticulture and table grapes on light calcareous country around Mildura and Robinvale.

Goulburn Valley & northern Victoria

Pome and stone fruit, dairy pasture and irrigated cropping, where secondary nutrients are dosed alongside the micros.

Riverina, New South Wales

Irrigated cereals, rice, citrus and cotton on heavy soils, with blends built for fertigation as much as for spreading.

Northern NSW & the Darling Downs

Grain and cotton on alkaline vertosols, where zinc and manganese are the usual limits.

Queensland tree crops & cane

Macadamia, avocado, citrus and sugar from the Sunshine Coast to the Atherton Tableland — high-value crops where chlorosis is visible and costly.

Tasmania & the south-east

Vegetables, berries and high-value horticulture in cooler soils, with foliar grades doing more of the work.

Ord River & northern Australia

Mangoes, melons and cotton under irrigation in the Kimberley and the Top End.

Common questions
Do you supply finished fertiliser products?

No. Everything in the Grow range is supplied as a raw material for blending and formulation. Inclusion rates, compatibility with other inputs, and the composition, registration and labelling of the finished product remain the responsibility of the blender.

When do we need EDDHA rather than an amino-acid chelated iron?

On neutral to mildly acidic ground an amino-acid chelated iron does the job economically. Above about pH 7.5 it loses its grip: the iron comes off the ligand and precipitates as ferric hydroxide, and in that form the plant cannot take it up. EDDHA is the most stable of the common iron chelating agents across the alkaline range and stays in solution to around pH 9, so it is the grade for calcareous country rather than a replacement for the other.

What pack sizes do you supply?

Bags or bulk bags, to suit your intake and handling. Tell us the volume and how you take material in, and we will quote the pack size that fits.

What documentation comes with a batch?

A certificate of analysis against the specification, with batch numbers carried on the pack for traceability through to your finished grade. Technical and safety data sheets travel with every order, and retained samples and additional analysis are available on request.

Can you help us check compatibility in our own blend?

Yes. We can generate compatibility test data on request, so a trial answers how the materials behave in your blend rather than only what they are.

Tell us which lines you want

The materials you are interested in, the grades they are going into, and an indicative annual volume — that is enough for us to quote and send the sheets.
