The project aims (i) to collect field data that can be pooled with existing data from the Better Fertiliser Decisions for Crops database (BFDC) to assess the applicability of recommended soil critical values for the HRZ of southern Australia, (ii) quantify the effects
of nutrient deficiencies on grain yield, and (iii) identify the main nutrients limiting grain yield for the purpose of conducting rate experiments in subsequent years.
• Regional survey on the nutrient status of nitrogen (N), Phosphorous (P), Potassium (K), Sulphur (S) and the micro-nutrients Zinc (Zn) and Copper (Cu) of soils in the HRZ of south-eastern Australia undertaken and status report prepared.
• Two omission trials sown in 2015 to test crop yield response and the interactions between nutrients where N, P, K and S and micro-nutrients Zn and Cu are omitted.
• Seasonal conditions resulted in the only responses being received from nitrogen applications; the omission trials to be repeated in 2016 under different seasonal conditions.
