Soil testing to optimise agricultural production
Western Australia’s soils, particularly those in the south west corner of the state are unique in that they can be sandy, acidic, salty and water repellent (hydrophobic) they also often lack the nutrients and trace elements needed to optimise agricultural production.
ChemCentre scientists developed the Phosphorus Retention Index (PRI) test to characterise phosphorous requirements of Western Australia’s soils.
The PRI test has enabled a measure to be applied to optimise agricultural production while at the same time protect the environment.
The test typifies the scientific assessment of WA soils and the relationship that phosphorus fertiliser has played in agriculture production and responsible use of fertilisers in sensitive environmental catchments.
