In the FARMERS HELPING FARMERS PODCAST Episode 21, Dan Fox sits down with WA farmer Rob Hetherington who is seeing a lifetime of soil study come to fruition on the Lake King farm he runs with his wife Judi and son Daniel, Kate and family.

This is a fascinating and indepth discussion with an experienced farmer and Wheatbelt NRM Soil Health Champion who was a guest speaker at VicNoTill's 2024 Food for Thought Conference.

Rob discovered a long time ago that calcium was the limiting factor to his soil health on the cropping farm that has been in his family since 1946. Rob and Judi took over the management of ‘Walma’, named after Rob’s parents Wally and Mary, in 1983. They grow multi-species for a dairy as part of an ongoing arrangement, as well as winter grains and opportunistic summer crops.

Using his scientifically-geared knowledge he identified calcium, along with some phosphate, as being the first step to bringing their whole system together.

Calcium has stimulated their root, stem and foliage growth, helped build stem strength in crops and made them more resistant to attack by disease or insects and helped raise Brix levels which helps them withstand frost.

Rob's most important lesson of all is understanding that knowledge is power.

"In the regenerative space there’s a lot of talk out there that you’ve got to look after the soil biology, so put a crop in with minimal fertiliser or no fertiliser. This might work on some areas and you might get away with it one year. In the long term though, it’s a downward spiral. I know that because I’ve experienced it myself. It’s a matter of knowing the chemistry and the biology, finding that knowledge and moving forward from there. At the end of the day, farming is all about mineral energy and controlling conductivity and knowing what to apply and where to apply it to get those reactions happening.”
