"Small enough to care, large enough to make a global difference."
World-class liquid plant nutrition to maximise yield and quality
Protecting crops without compromising biodiversity or the bees
100% Australian owned, operating from Goondiwindi QLD
Growth Agriculture has been manufacturing, exporting and distributing agricultural products since 1992 - building a focused portfolio around foliar nutrition and Integrated Pest Management (IPM).
We're a small Queensland company with a straightforward belief: Australian producers deserve partners who actually understand the land, not just the product catalogue.
Sustainable and environmentally acceptable agriculture practices are at the forefront of everything we do. We aim to develop products that enhance food and fibre production while protecting the land for future generations.
We proactively seek out innovations that aid in environmentally acceptable production, source products that maintain or improve land management practices, and provide growers with the information they need to succeed.
From the paddock to the distribution network - our products, data, and people are available to support you at every level.
From broadacre cropping and intensive horticulture to cotton and mixed farming - our products are designed for the realities of Australian production. Better inputs, better margins, healthier soils.
We back every recommendation with data. Trial reports, mode-of-action documentation and research papers are all available - because your advice needs to be defensible.
We partner with distributors and rural resellers who are serious about quality. Our niche product range differentiates your offering and carries real market demand.
Agricultural corporates, food businesses, and institutions looking to document environmental responsibility will find a valuable partner in Growth Agriculture. We support ESG objectives with products that genuinely reduce environmental impact.
More than 30 years developing and manufacturing cost-effective inputs for Australian agriculture - from soil fertility to botanical pest control.

Browse allThe next generation of botanical bio-pesticide. APVMA registered, organic certified, 100% safe for bees and pollinators, and proven to control a broad spectrum of insect pests and diseases.
Learn moreWe punch well above our weight in R&D expenditure. From the world's first peptide-based botanical bio-pesticide to biological nitrogen replacement trials, our science is field-proven and peer-reviewed.
Developed in collaboration with research institutions including Southern Cross Plant Science, the University of Queensland, the University of Western Sydney, and the NSW Department of Primary Industries.
Sero-X is a world-first plant-extract bio-pesticide containing a revolutionary set of peptides called cyclotides as its primary active compounds. It is non-toxic to mammals, beneficial insects, and 100% safe for bees and pollinators - while controlling a broad spectrum of insect pests.
NEW: Research and Supply Permit PER93075 - contact us to find out if your operation qualifies.
Learn more about Sero-X®Intensive agriculture has become reliant on synthetic inputs such as Urea. The effect of these traditional fertilisers on soil biology can be detrimental - and costly to reverse.
Our long-term field research into B&B Superfine as a biological partial nitrogen replacement demonstrates improved soil biology, competitive yields, and reduced long-term input costs.
View trial resultsOur R&D is conducted alongside some of the world's most reputable scientists from industry-leading institutions. We believe in transparent, independent, replicable research - and sharing those results with growers and agronomists who need them.
Technology & evidence hubFrom the first handful of ash on a Neolithic plot to a paddock of B&B Superfine, the story of fertiliser is a long conversation with the ground. Fourteen milestones, four eras, one unbroken thread - ending here in Goondiwindi.
In Neolithic Mesopotamia, crops planted where hearth-fires burned or kitchen scraps piled up grow taller. Humanity starts returning carbon and minerals to the soil.
Once animals are domesticated, dung is carted back to cropping ground — the oldest deliberate fertiliser on record.
Annual Nile floods deposit mineral-rich silt across the valley — the first industrial-scale proof that minerals, not just manure, matter.
Greek and Roman farmers formalise crop rotation with legumes. Nobody yet knows about nitrogen-fixing bacteria, but it becomes written law in Rome's agricultural treatises.
Chinese agriculture builds an entire logistics network around human waste — composted, aged, and returned to rice paddies for two thousand years.
Medieval manors divide arable ground into three — winter grain, spring grain, and fallow grazed by livestock. The workhorse of European fertility for five centuries.
Vast cliffs of fossilised seabird droppings off Peru — 15% nitrogen and high in phosphorus — become one of the most valuable cargoes on the high seas.
John Bennet Lawes treats crushed bones with sulphuric acid, producing soluble phosphate fertiliser. The Rothamsted patent marks the beginning of the industrial fertiliser industry.
Justus von Liebig proves plant growth is limited by whichever nutrient is in shortest supply. Fertiliser becomes a diagnostic problem: find what the soil lacks, give it exactly that.
Fritz Haber and Carl Bosch combine atmospheric nitrogen with hydrogen at industrial scale. The process today feeds an estimated half the people on Earth.
High-yield grain varieties married to cheap synthetic NPK triple cereal output across the developing world in a generation. Famines recede. So, quietly, does soil biology.
As synthetic-reliant soils show salinity and microbial collapse, growers turn back to biologicals, humic acids, and foliar nutrition. Fertiliser becomes something you feed to the microbes, not just the plant.
A small Queensland company begins manufacturing agricultural inputs from the Macintyre River country. The brief: cost-effective products that respect the paddock.
Growth Ag renders blood and bone into a stable, superfine liquid — tank-mixable, foliar-applicable, or banded at sowing. The oldest ingredient in the newest form.
