Fenrow pioneers leading-edge sustainable fertilisers for agriculture, designed using novel resource-management technologies for a circular future.
Explore the product →01 / Next-gen fertilisers
Fenrow fertilisers contain all essential crop nutrients with optimised release rates, supporting greater nutrient efficiency with less impact beyond the crop.
The organo-mineral formulation combines a complete nutrient profile in optimal ratios with carbon that supports soil fertility, microbial activity and water-holding capacity.

Organo-Mineral G1
A data-driven design provides tailored nutrient release for immediate plant establishment and sustained growth. The current formulation is designed to feed plants over specified time periods.
02 / What the product stands for
99% renewable or sustainable sources in Organo-Mineral G1, with a target above 99.5%.
Research undertaken with high-calibre research institutions and published in Q1 peer-reviewed journals.
EU 2019/1009 compliant and less than 0.001% lead, arsenic and cadmium.
03 / Our motivation
Designed to reduce nutrient-loss pathways that contribute to fertiliser-related greenhouse-gas emissions.
Complete crop nutrition with carbon supports plant growth and biological soil function.
Recovered inputs return nutrients and carbon to productive soils while reducing reliance on virgin resources.
Tailored nutrient release is designed to retain more nutrition in the crop and reduce movement to waterways.
Range reported for most conventional control plots in a global field-study synthesis.
Attributed to synthetic nitrogen-fertiliser production.
Attributed to nitrogen fertiliser after application.
Sources: nitrogen recovery efficiency, production emissions, and applied emissions.
See the business case →A fertiliser only earns its place when it works for the crop and the production system. Fenrow connects the agronomic case with operator needs: effective nutrition while simplifying and standardising nutrient protocols.
Domestic production means less influence from volatile foreign markets and greater price stability for primary producers and consumers.
All essential nutrients in an organo-mineral formulation designed to match crop demand and sustain growth.
A single pre-manufactured input below the root at sowing, with standard unamended media above.
Recovered and sustainable resources that are produced domestically, reducing exposure to foreign fertiliser markets.
The design objective is to retain more nutrition in the crop and reduce losses to emissions and waterways.
Successive prototypes were assessed through laboratory, glasshouse, industry-led and field studies. Fenrow carries that body of research forward into a commercial organo-mineral fertiliser program.
The first next-generation prototype was compared with novel and commercial fertilisers in a temperature-controlled glasshouse study, later published in a Q1 peer-reviewed journal.
A second formulation was tested with an industry partner in South Australia to assess soil and agronomic benefits under field conditions.
Controlled work evaluated nutrient-release and leaching dynamics against commercial monoammonium phosphate and superphosphate.
The current pathway tests Fenrow against incumbent nutrition programs in the relevant crop, container and production environment.
05 / Evidence before scale
Agree on the crop, container, incumbent program and the commercial or agronomic question worth answering.
Generate relevant evidence in the grower’s production environment, with measures agreed before potting begins.
Advance when crop performance, operational fit and the agreed business criteria support the next step.
Fenrow, directly
Plain answers to the questions most often asked about Fenrow, organo-mineral fertiliser and the trial pathway.
Fenrow develops controlled-release organo-mineral fertiliser containing essential crop nutrients and carbon-bearing material. The current program is evaluated through structured trials in Australian growing systems.
Fenrow’s current focus is Australian growers and production nurseries. Product fit is confirmed for each crop and container before a trial begins.
Fenrow compares its product with the grower’s incumbent nutrition program in the relevant crop, container and production environment. Measures and decision criteria are agreed before the trial begins.
Organo-mineral fertiliser combines organic material and declared mineral nutrients in one formulation. Its performance depends on the specific formulation, crop, growing system and conditions.
Fenrow helps primary producers quantify and improve sustainable production, providing nutrient inputs aligned with Australian, EU and global sustainability initiatives.
The Fenrow SAFA assessment used the United Nations’ internationally recognised framework to benchmark environmental, social, economic and governance performance.
Fenrow reinvests 100% of its profits into research, communities and producers.
Commitment to transparency across research and development.
Carbon-neutral operations and sustainably sourced materials.
06 / Scientific leadership
Managing Director Dr Michael Walsh leads Fenrow’s scientific and commercial direction. His work spans circular nutrient systems, recycled fertiliser performance, organo-mineral fertilisers and crop nutrient acquisition.
Fenrow works with government, industry, academia and primary producers to find real-world solutions for complex sustainability problems.
