Controlled-Release Organo-Mineral Fertiliser Technology

How it works

Nutrition that keeps pace with the crop.

A Fenrow pellet 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. New to the category? Read our plain-English guide to organo-mineral fertiliser.

Release matched to demand

Release is governed by the pellet rather than by weather. The aim is to put more of every applied kilo into the plant and less into the drainage.

Recovered, sovereign inputs

Nutrients are recovered from Australian waste streams and processed into consistent, analysed feedstock. This can displace imported virgin inputs while reducing exposure to global price shocks and supply disruption.

Organo-mineral base

The mineral fraction provides specified crop nutrients; the organic fraction contributes recovered material. Fenrow combines the two in a single pellet rather than blending separate products after the fact.

A coating that exits cleanly

The supporting act has a long tail. Fenrow’s coating is engineered to do its job for the season and then break down in soil. It has been designed with the direction of EU microplastics regulation in mind.

Product fit

Where Fenrow fits today.

We would rather tell you exactly where the current range performs than promise everything to everyone.

Production nursery pots and containers

This includes potted colour, trees, shrubs and wholesale greenlife. These formats have some of the highest fertiliser use per cubic metre of growing media, where cost per pot is felt directly and where Fenrow leads today.

Tube stock and ≥40 mm cells

Media-incorporated pellets perform particularly well in these propagation formats. Recycled irrigation loops also make leachate an operational measurement rather than an abstract concern.

Small plug cells

Tiny plug volumes constrain pellet 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

Asked by growers, answered plainly.

How is this different from the controlled-release fertiliser I already use?

Three things. The nutrients are recovered from Australian streams, so your supply does not ride import price cycles. The release program is designed for efficiency and tested against your current product on your own benches. Afterwards, the coating is engineered to break down rather than leaving persistent shells in your media.

Will it match the release performance I rely on?

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.

What is in it?

An organo-mineral nutrient base built on recovered nutrient streams, finished with a coating engineered to break down in soil. Coating composition is proprietary; full analysis and handling documentation accompany every commercial supply discussion.

Where do the recycled inputs come from?

From quality-controlled Australian recovered nutrient streams processed into consistent, analysed feedstock. Consistency is both a release requirement and fundamental to sovereign supply. A pellet cannot release predictably if its nutrient base is unpredictable.
