The technology
How a Fenrow granule turns recovered Australian nutrients into crop growth — efficiently, and with a clean exit.
How it works
A Fenrow granule has three jobs, in order: put more of every applied nutrient into the crop, build that nutrition on recovered Australian streams, and exit cleanly when the season is done. Each part of the system is built for one of those jobs.
Release is governed by the granule rather than by weather. Nutrients become available in step with crop uptake, so more of every kilo applied ends up in the plant — and less in the drainage.
Nutrients are recovered from Australian waste streams and processed into consistent, analysed feedstock. That displaces imported virgin inputs — and with them, exposure to global price shocks and supply disruption.
Mineral nutrition delivers the analysis and consistency commercial growing demands; the organic fraction supports soil biology and structure. The two are combined in a single granule rather than blended after the fact.
The supporting act with a long tail: Fenrow’s coating is engineered to do its job for the season and then break down in soil — designed from the outset around the direction of EU microplastics regulation.
Product fit
We would rather tell you exactly where the current range performs than promise everything to everyone.
Potted colour, trees and shrubs, wholesale greenlife — the formats with the highest fertiliser use per cubic metre of media, where cost per pot is felt directly, and where Fenrow leads today.
Propagation formats where media-incorporated prills do their best work — and where recycled irrigation loops make leachate an operational number, not an abstraction.
Tiny plug volumes constrain prill dosing. In those formats we position Fenrow alongside fertigation rather than in place of it, and we will say so plainly. The range expands as the coating portfolio matures.
On the coating itself: coating composition is proprietary. Performance is demonstrated under our fixed side-by-side trial protocol, and the substantiation file behind every claim is available on request.
Common questions
Three things. The nutrients are recovered from Australian streams, so your supply doesn’t ride import price cycles. The release program is designed for efficiency — proven against your current product on your own benches. And afterwards, the coating is engineered to break down rather than leaving persistent shells in your media.
That is precisely what the trial protocol exists to demonstrate on your benches, against your current program, with thresholds fixed before the trial starts. We would rather show you than tell you.
An organo-mineral nutrient base built on recovered nutrient streams, finished with our biodegradable coating system. Coating composition is proprietary; full analysis and handling documentation accompany every commercial supply discussion.
From quality-controlled Australian recovered nutrient streams processed into consistent, analysed feedstock. Consistency is both a release requirement and the backbone of the sovereign-supply story — a granule cannot release predictably from an unpredictable base.
Nurseries, agronomists, media blenders and distribution partners — if putting more of every nutrient into the crop, from sovereign Australian inputs, fits your operation, we would love to hear from you.
