We undertook three studies into the potassium requirements of high rainfall pastures: 1. Between 1999 and 2009, soil testing was conducted in 48 dairy paddocks at Vasse Research Centre (VRC) in the south-west of Western Australia (WA). This study will be referred to as the VRC soil test study.
2. Between 2002 and 2007, a potassium experiment was undertaken at Boyanup to improve our knowledge of potassium requirements of intensively grazed ryegrass pastures. This will be referred to as the Boyanup potassium experiment.
3. Between 2006 and 2010, potassium experiments were undertaken on two partner farms of the Greener Pastures project. These will be referred to as the partner farm potassium experiments.
