SUPER PHOS® and SUPER NITRO® Improve Spring Wheat Grain Yield and Quality

Research by Olga Walsh, PhD, University of Idaho

The objectives of this study were (1) to compare the Micro Carbon Technology®-based phosphorus (P) product Super Phos® (SP) with traditional phosphorus (P) fertilizers ammonium polyphosphate (APP), and diammonium phosphate (DAP); and (2) to compare the Micro Carbon Technology®-based nitrogen (N) product Super Nitro® (SN) with the traditional nitrogen fertilizer, UAN.

Huma Gro® Super Nitro® followed by 30 lb P2O5 per acre of Super Phos® (Treatment #3) contributed to the highest grain test weights, biomass, and yield.

This study also indicates that Super Phos® is less corrosive and less likely to cause damage to the seeds as a dribble and suggests that Super Phos® could be applied with the seed at a higher rate compared with other P sources.
