Description

Viable pasture based grazing systems in south-western Australia have been made possible over much of the landscape through input of nutrients to soils which were impoverished when first cleared. Initial dramatic increases in production stimulated subsequent applications of fertilisers, particularly phosphatic fertilisers, ever since. However, excessive fertiliser application can be tied to environmental impacts including the loss of phosphorus (P) to waterways impacting on water quality.
