Gypsum has both short and long-term impacts on soil sodicity. In the short term it increases salinity to suppress dispersion. In the long term it replaces sodium on soil particles with calcium.

Potassium depletion of loamy soils in Western Australia has been the subject of new attention. Better growth in windrows on these soils could be an indicator of declining soil potassium supply more broadly across these soil types.

Some growers are looking at gypsum as an option to tackle subsoil acidity. As gypsum is more soluble than lime, some people think that gypsum and lime will move into acidic layers faster than lime alone, and that gypsum can counteract toxic aluminium.
