Dr Mary Cole has spent more than 40 years working with the microbial life that underpins healthy soil. In this episode, she shares what she's learned from a career in plant pathology and soil microbiology, and from farming using compost products, aeration and no synthetic inputs on her own property in Gippsland Victoria. Mary explains how simple practices like aeration, compost, and soil and plant observation can make a big difference to soil function.
