Being Green

Last week on Being Green, Glynis Crook spoke to 13-year-old Quinley Wild about his song - SOS or Save our Soil. He wrote it after his mom got involved in a global movement to address the crisis of soil degradation. To find out more about why taking better care of our soil is crucial, this week Glynis speaks to Dr Ailsa Hardie, a senior lecturer in soil chemistry at Stellenbosch University.
