Cliff Hignett has trained TAFE students in land mangement, university graduates in soil physics, and helped communicate the latest developments in soil science to wheat farmers across South Australia. He is acredited as a trainer with the Kadina TAFE - more substantial workshops may attract govt. subsidy. FARMBIZ questionaires showed farmers rated his work extremely highly, with as many as 80% of farmers saying they learned something new that they would apply on their properties.
