Our Team
iFert soil & fertiliser consultants are highly trained, well-qualified nutrient advisors with more than a decade of experience across all schools of fertiliser practice. We have no commercial bias towards any fertiliser supplier and view this independence as one of our greatest strengths. iFert is committed to the bigger picture — a sustainable and profitable future for New Zealand and Australian agriculture.
Corey Martin
With over two decades of experience in the fertiliser industry, Corey has held senior roles as a field consultant and technical specialist since 2003. In 2012, he founded iFert with the vision of offering clients an independent, unbiased approach—ensuring access to a broad range of products and expert advice tailored to individual needs.
Corey now serves clients across New Zealand and Queensland, Australia’s sugar cane capital, where he has pioneered an industry-leading Soil & Plant Diagnostics service. This innovative service allows for the precise identification of production-limiting factors both above and below ground, helping farmers optimize yields and sustainability.
Corey is highly qualified in Sustainable Nutrient Management and Sustainable Agriculture, and his work continues to set new benchmarks for efficiency and environmental stewardship in the agricultural sector.
Nathan Congreve
With over 20 years in the fertiliser industry, Nathan brings deep expertise and a bold, soil-first mindset to i-Fert. He joined i-Fert in 2015, following nearly a decade of working alongside Corey Martin in various roles within the sector. Armed with an Honours degree in Horticulture (specialising in soil science) and qualifications in Sustainable Nutrient Management, Nathan is driven by one clear mission: helping farmers unlock the full potential of their soil to build long-term profitability.
Scott McLean
Scott is a third generation sugarcane farmer from Mackay, Queensland. He has worked on the family farm since the age of 14, slowly expanding the operation to double its size. Scott has also completed a stint as a miner and a superintendent for Rio Tinto and he runs his own aerial spraying business.
Scott sees diversification, efficiency and continuous improvement as the way to counter price fluctuations and unpredictable weather. His experience with Corey Martin on his own farm has led Scott to get directly involved in the iFert business. Scott heads up iFert, Australia.
