8-16-9 Bonus Plus (In-Furrow) + Bio-Forge (Foliar) (35-55 bu/A Medium Yield Zone)

Treatment Information
Bonus Plus fertilizer, which consisted of 8-16-9-1-0.45 (N-P-K-S-Zn), was
applied in-furrow at 2.5 gal ac-1 in the two treatment strips (Figure 1).
Bio-Forge (N,N’ – diformyl urea) was also added to the mixture at 8 oz
ac-1, which is marketed to relieve stresses, especially from drought. A
second foliar application of Bio-Forge was also made at R2

Agronomic and Weather Information
Soybeans with a 1.5 maturity rating were no-tilled into corn stalks in 30”
rows on May 13. Seed was treated with insecticide, fungicide, and a B.
japonicum inoculant. The field received approx. 7.82 in. of rain and
accumulated 1823 GDDs from June 1 through August 31. This was drier
and warmer than the average of 10.57 in. and 1755.15 GDDs.

Results
Overall, the treatment did not significantly increase yields (Table 2).
However, with only two reps, statistical significance is very difficult to
achieve. These results appeared somewhat better than those from a
trial in this same field where only Bonus Plus was tested. The relatively
low yield of this field may explain why a product like Bio-Forge may
have been effective. Bio-Forge was less effective in a higher-yielding
2016 Kingsbury Co. soybean field.
