Managing nutrition on sandy soils - fertiliser source

Sandy soil types of the Northern Mallee often underperform despite good weed management and increased inputs of nitrogen and sulfur. There is still a yield gap that can be addressed, with anecdotal evidence of unused water commonly remaining in the soil at depths of approximately 60cm at harvest.After several years of demonstrating the value to wheat production of increased nitrogen inputs on sands at Karoonda, it was time to explore nutrition packages at a broader set of Mallee sites.
