These trials were conducted to examine the likelihood of economic returns to VRT on sandplain soils.  

• In a below average rainfall year, with a very dry finish gravelly sands were still highly responsive to applied P, with 0.6 t/ha response to 60 kg/ha P over the last two years and 30 kg/ha applied this year
• Nitrogen in the absence of phosphorus did not significantly increase yield at either site.  This highlights the requirement to get your P rates tailored to your potential at seeding time, as low P rates may limit N response in a good year.
• There was strong correlation between early vigour and grain yield at both sites, again highlighting the need to establish a strong, healthy crop with sufficient early nutrition.
• Increasing plant numbers did not result in increased grain yield on poor sands.
• This trial shows that on variable light country variable rate fertiliser applications would be a useful tool to improve nutrient use efficiency on variable sands, as both sites had significantly different yield potential and nutrient requirement.
