The aim of this project is to assess selected amendments or additives to monoammonium phosphate to reduce the precipitation of soluble phosphorus in calcareous, alkaline and high phosphorus buffering index soils in SA’s Lower South East.

Evaluating commercial products to enhance phosphorus fertiliser efficiency (ASO5225)
This project addresses one of SAGIT’s issues of significance, a critical evaluation of products claimed to improve the efficacy of phosphorus fertilisers. This will be done by focusing on improving Phosphorus Use Efficiency (PUE) on moderate to highly calcareous soils that are present on Eyre Peninsula, Yorke Peninsula, Mid-North and the Upper South East broadacre cropping regions.
Making the most of phosphorus(P) fertiliser inputs: Managing spatial variability and long-term strategies (TCO6024)
The overall aim of this project is to increase the profitability from phosphorus (P) fertiliser applications and determine sustainable P fertiliser strategies. This project focuses on two key P management areas: improving applications in variable paddocks/landscapes and refining long-term P management strategies on highly P responsive soils. This project will build on the results from SAGIT projects TC219 and TC221. This project is a co-investment, with GRDC providing 50% of the total funding.
Improved management of variable phosphorus requirement and strategies for highly responsive soils (TC221)
Phosphorus (P) response prediction based on spatial data in variable soils is to be validated in a series of field trials encompassing different soil types. Best practice for long term management of high P response sites is to be determined.
