Soil Science Australia’s Certified Professional Soil Scientist (CPSS) accreditation seal is the mark of trust, expertise and excellence in soil science. Engaging a CPSS helps reduce risk, increase certainty and achieve better soil and land management outcomes. This profile is one in a series featuring new CPSS members.

Dr Degens brings over three decades of dedicated experience to the intersecting fields of soil science and geochemistry, focusing on their large-scale impacts on water quality.

His professional journey began with pioneering research into soil health indicators across the UK, New Zealand, and Australia, quickly establishing him as a trailblazer in the study of microbial function diversity. This innovative approach solidified his reputation, particularly in Western Australia, where he has become a go-to expert for addressing the effects of soil on both groundwater and surface water quality.

Dr Degens’ expertise spans hydrology, geochemistry, and hydrogeology, equipping him with a unique set of skills to develop ground breaking solutions for environmental challenges. He is especially adept at managing the complex issues presented by both coastal and inland acid sulfate soils, which pose significant risks to ecosystems and human health.

In his current role, Dr Degens works closely with a network of farmers, agronomists, and land care officers. Together, they implement strategic interventions, such as the use of clays and high phosphorus-sorbing mineral products, aimed at enhancing nutrient retention within farming systems. These initiatives not only improve soil health but also significantly reduce any negative impacts on water quality, demonstrating his commitment to practical and sustainable environmental practises.

Recently, Dr Degens’ expertise and contributions to the field have been formally recognised with his accreditation as a Certified Professional Soil Scientist (CPSS) by Soil Science Australia. This accreditation is a testament to his profound knowledge and professional commitment to soil science, further validating his role as a pivotal figure in the pursuit of sustainable solutions for complex soil and water quality issues.

Dr Degens’ said: “Being a CPSS member means becoming part of many minds working to promote the science of soils, lift standards in these, broaden knowledge and engage others to consider doing the same”
