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.
This project aims to assess the impact of organic amendments on soil condition and crop response on three contrasting soil types. Through this process, the aim is to provide growers with recommendations on ‘target soils’ where organic amendment applications can provide maximum benefit. Researchers will endeavour to define suitable frequency and application rates of organic amendments in combination with inorganic fertiliser.
