Trial location(s) Lake Bolac, VIC
Enhancing phosphorus fertiliser efficiency in wheat locations
Aims

To assess whether phosphorus utilisation can be enhanced through the use of liquids, compound fertilisers and slow release coated fertiliser options.
 

Key messages
  • Phosphorus rates of 10 and 20 kg/ha applied in various straight, compound, coated and liquid fertiliser forms were not found to result in any significant responses in grain yield or quality.
  • Results were impacted by the failure to control a population of herbicide-resistant annual ryegrass at this trial site using both pre- and post-em herbicide options, resulting in a high variability between plot measurement.
