#23 The Basics: Acid Sulfate Soils

Below the Surface

Acid Sulfate Soils are a tricky subject. The second episode of our "The Basics" series is all about the ASS (oh this acronym is just endlessly amusing, isn't it?). Gunnar and James' guest is Laurie Fox, one of the most recognised and distinguished ASS experts not only in Australia, but globally. Aside from doing fantastic assessment and ASS management work on mind bogglingly big projects himself, Laurie is also committed to improving our industry's understanding of these soils.
This improvement pathway he is on involves not only industry talks like this one, but also a tireless commitment to liaison with and education of various regulators. People like Laurie are a rare breed, one that is vitally important to have in our industry. It is people like him who improve all of us.
