Of the many presentations, the following two papers are relevant to Australian growers and crop nutritionists.
Dr Cassandra Schefe works with Monash University. Her research investigates microbe activity and available P. Australia’s soils are often low in P. Less than 15% of that soil P is available for plant uptake. Soil microbes can make more P available to plants. Addressing some soil constraints helps microbes flourish.
Dr Malcolm McCaskill spoke on behalf of a research group. Their work focusses on the Victorian high rainfall zone (HRZ). Critical soil levels proved higher in HRZ cropping paddocks when compared to other rainfall zones. They suggest a crop nutrition strategy for the HRZ. The timing for different fertilisers is a focus.
