To evaluate the responsiveness of wheat, barley and canola to phosphate fertilizer on a wide range of soil types across Alberta to determine the frequency of when each crop will respond to phosphate fertilizer. To correlate P soil test methods with crop response to phosphate fertilizer over a wide range of Alberta soils. Correlation would then allow development of optimum phosphate fertilizer requirements for wheat, barley, and canola in all soil zones for use by soil testing labs.
