Potassium is second only to nitrogen in the quantity required by plants for healthy growth, but Australian agriculture has traditionally relied on the native soil resource of potassium. Increasing incidences of costly potassium deficiencies coupled with the need to fertilise responsibly to avoid environmental and animal health consequences demonstrate that we need a better understanding of K dynamics in soils, plants and animals in our agricultural systems. In 1997 the sucessful First Workshop on Potassium in Australian Agriculture was held in Geraldton, WA and highlighted the research community’s understanding of K nutrition in Australian agricultural conditions at the time. Since then, further research has improved our understanding, identified deficiencies in new crops and regions and also highlighted what work yet needs to be done.
POTOZ‘05, the Second Workshop on Potassium in Australian Agriculture will allow the research community to exchange new findings, determine future priorities and identify opportunities for future collaboration and funding. With several overseas guests, it will also be an opportunity to learn from the experiences of researchers in other countries. This one day workshop is essential for those working towards improved nutrition of crops and pastures in Australia.
