Potato growers in the Gingin and Dandaragan areas face significant production challenges due to highly variable soil types under centre pivots. One problem during tuber establishment is where irrigation decisions for lighter soil types result in overwatering on heavier soil types, resulting in rotting of seed pieces on the heavier soils. On the other hand, optimizing irrigation for heavy soil types results in underwatering of seed pieces on lighter soils. The trial is being conducted in Gingin and Dandaragan on sandy and loamy soils respectively. This report covers the pre-trial testing results.
