It is estimated that three million hectares of water-repellent, sandy-textured soils in Western Australia and South Australia could benefit from clay application.. Clay spreading in WA is economical if the clay source is within half a kilometre of the area where it is to be applied.. Mr Hall says claying achieves yield increases by overcoming constraints that include: uneven distribution of soil moisture leading to poor or staggered emergence of crops and weeds; low nutrient-holding capacity; potassium deficiencies; and wind erosion...

Mr Hall says claying achieves yield increases by overcoming constraints that include: uneven distribution of soil moisture leading to poor or staggered emergence of crops and weeds; low nutrient-holding capacity; potassium deficiencies; and wind erosion... Mr Hall says that through the MPCN project, initial sampling of 43 WA paddocks treated with clay showed some had a high phosphorus retention index (PRI), which makes phosphorus less available to crops in the short term... Mr Hall says researchers will also revisit long-term clay trial sites and study the paddocks of growers who have been using clay for long periods to assess how crop nutrition management has changed post-treatment...
