Application Placement Materials and Methods The corn field was located in Marshall, Minn.; the soil was a clay loam with 3.8% organic matter and a pH equal to 7.6. The design was a randomized complete block with two replicates per treatment. Each plot size was 4 rows x 60 feet. The treatment included (1) 100% P supplied with 1.225 GPA Super Phos ® , (2) 100% P supplied by 18.38 GPA 10-34-0, and (3) 50% P supplied by 0.613 GPA Super Phos ® plus 50% P supplied by 9.19 GPA 10-34-0. The fertilizers were broadcasted using a tractor-mounted plot sprayer. Results Table 1.

Figure 2. Corn Yield Assessment in Bushels Per Acre Conclusions Huma Gro ® Super Phos ® at 1.225 GPA increased corn yield by 99.15 bu/ac in comparison with 10-34-0 at 18.38 GPA. This demonstrates Super Phos ® to be 15 times more efficient than 10-34-0 at delivering phosphorus to corn and, at MSRP at the time of the trial, represented a 40% savings on fertilizer cost. Achieving higher yield while using much less product (7.62 lb of P 2 O 5 for Super Phos ® , vs. 72.6 lb of P 2 O 5 from the 10-34-0) has the added benefit of presenting much less opportunity for phosphorus soil-leaching and runoff into nearby water, thereby protecting the environment. It also facilitates sustainable agriculture through adherence to 4 R Nutrient Stewardship by applying the right source of plant nutrients at the right rate, at the right time, and in the right place. Bushels per Acre Treatment Super Phos ® at 1.225 GPA 10-34-0 at 18.38 GPA Super Phos ® at 06.125 GPA and 10-34-0 at 9.19 GPA 290 182.6 261.79 281.75 280 270 260 250 240 230 220 210 200 190 180 170 160 150 SP 10-34-0 Figure 1. Application Rates Per Acre, Super Phos ® vs. 10-34-0 GPA 1.225 = 7.62 lb P 2 O 5 GPA 18.38 = 72.6 lb P 2 O 5 HG-171019-01
