Abstract
Soil test P, K and S – yield response relationships for wheat, lupin and canola can be used to make better fertiliser decisions. Soil test using 0-10 cm soil samples provided reliable predictions of yield response to P when separated into soil types with different P sorption capacities. In contrast, soil sampling to 30 cm depth improved wheat and canola yield response prediction with the K soil test when the impact of soil acidity and potential yield on root distribution was taken into account. The deeper soil sampling to 30 cm improved the relationship for S canola but not for wheat where rate of S leaching and potential yield appear to be important. The N soil test-response relationships for wheat and canola were not significant and critical values could not be defined.
