Super Phos® (SP; 0-50-0) by Bio Huma Netics Inc. (Gilbert, AZ) is a Micro Carbon TechnologyTM – based phosphorus (P) fertilizer specifically formulated to resist “tie-up” with calcium (Ca) and magnesium (Mg) to remain water soluble and available to plant roots. The objective was to compare the efficiency and effectiveness of topdress and foliar application of SP, with traditional P fertilizers – ammonium polyphosphate (APP; 10-34-0), diammonium phosphate (DAP; 18- 46-0), and triple super phosphate (TSP; 0-46-0) – for optimizing spring wheat grain yield and quality. SuperPhos® has performed very well in terms of spring wheat grain yield and grain protein content in this study. SuperPhos® applied at tillering as a foliar spray has also performed well in terms of grain yield, but lower grain protein value of just 12% indicated that a possible N loss via volatilization of urea applied at seeding have impacted the results. Results indicated that application of SP at seeding at the rate of 30 lb P2O5 ac-1 is a good option for P fertilization in dryland spring wheat cropping systems of Montana.
