Growers and advisers in South Australia and Victoria are increasingly reporting underperforming crops, which they believe could be attributed to a lack of potassium (K).

Soil tests often show the levels are fine, but are those tests accurate for south-eastern Australia and has the grains industry relied on good K reserves in that part of the world for too long?

Dr Nigel Wilhelm is from SARDI, the South Australian Research and Development Institute, the research division of the Department of Primary Industries and Regions in South Australia. He’s leading a GRDC investment that is investigating the extent and severity of K deficiency across south-eastern Australia and assessing the best way to manage the issue.
