Circular nutrient systems
Moving phosphorus and nitrogen from linear, waste-generating systems towards recovery, reuse and agricultural value.
Leadership & scientific authorship
Managing Director, Fenrow
Michael leads Fenrow’s scientific and commercial direction. His research focuses on how recovered nutrients, fertiliser formulation and crop nutrient-acquisition strategies can work together in practical agricultural systems.
Scientific responsibility
Michael’s role at Fenrow is to connect research discipline with commercial product development: define the question, choose the relevant comparison, measure performance in the intended growing system and keep every conclusion inside the evidence.
That means published category research can guide formulation and trial design, but it does not become a Fenrow product claim until Fenrow has measured the outcome under stated conditions.
Areas of expertise
Michael’s recent work spans the nutrient source, the fertiliser formulation and the plant processes that determine whether those nutrients can be used.
Moving phosphorus and nitrogen from linear, waste-generating systems towards recovery, reuse and agricultural value.
Testing whether recycled and organo-mineral nutrient sources can deliver agronomic value for specific crops and production conditions.
Understanding how crop genetics, root exudates and nutrient solubility influence access to conventional and recycled phosphorus.
Using controlled comparisons, product specifications and visible limitations to move from a promising nutrient source to a credible fertiliser.

These publications establish Michael’s expertise in circular nutrient economies, recycled fertiliser performance, organo-mineral fertilisers and plant access to recycled nutrients.
Research article · npj Sustainable Agriculture
Examines how sorghum genotypes differ in their ability to access phosphorus from conventional and recycled sources.
Research article · Journal of Plant Nutrition and Soil Science
Compares recycled phosphorus sources across crops and demonstrates why formulation, nutrient properties and target-crop testing matter.
Research article · Nutrient Cycling in Agroecosystems
Investigates crop-specific responses to compost, organic recyclates and organo-mineral combinations as nitrogen sources.
Doctoral thesis · The University of Queensland
Brings together the agronomic, resource and circular-economy questions involved in developing future phosphorus systems.
Perspective · npj Sustainable Agriculture
Sets out the need for nutrient recovery, waste valorisation and agricultural strategies that reduce dependence on a linear phosphorus economy.
