Viable pasture based grazing systems in south-western Australia have been made possible over much of the landscape through the input of nutrients from external sources to largely sandy soils which were impoverished when first cleared. Initial dramatic increases in production stimulated subsequent continual applications of fertilisers, particularly phosphatic fertilisers, ever since. Continued application has led to losses from soils saturated with P creating unwanted offsite environmental impacts. Diffuse phosphorus (P) loss from grazing agriculture (beef, dairy, sheep) has been a problem for water quality in coastal rivers and estuaries in south west Western Australia (SWWA) since the 1960’s. Toxic algal blooms and fish kills has led to investment in engineering solutions that treat the symptoms, but few practices that treat the causes of nutrient loss have become normative behaviour in agricultural enterprises. Low phosphorus buffering index (PBI) sandy soils (PBI <35) make up 30% of soils in the high rainfall agricultural area of the southwest of western Australia. These soils provide some unique challenges for managing nutrient movement offsite and agricultural practice. Many practices once considered best management, for managing phosphorus loss, on these low PBI soils have subsequently been shown to have limited impact. We will discuss the challenges these Low PBI sandy soils present, and the nuances required in managing them for nutrients. We investigate the impact of a range of strategies and BMPs and the direction and potential of future BMPs that are being considered going forward.
