Higher leaf-sap Brix at R3
Across three sampling dates, BOOST-treated soybean plants averaged 14.9 Brix compared with 6.8 Brix in the untreated check.

Brix by sampling date
How to interpret it
Higher Brix can indicate greater soluble-solids production and more energy available for growth, nutrient conversion, reproductive development, and natural defense. Less insect leaf feeding was also observed on treated plants, but that observation does not establish pest control or prove cause and effect.
Protocol: R3 soybeans, three sampling dates, 11:00 a.m.–12:00 p.m., full sun. Brix is a comparative field indicator, not a stand-alone yield predictor or guarantee.

Key Takeaways
Nitrogen Efficiency Improvements
L-CBF products consistently improve nitrogen use efficiency, allowing growers to achieve equal or higher yields with less nitrogen applied. The Martinsville trial showed a 17% reduction in nitrate leaching while gaining +13 bu/ac.
Synergistic Program Benefits
Combining in-furrow starter with foliar applications shows synergistic responses greater than either application alone. The Brooklyn soybean trial showed +15.20 bu/ac with the combined approach.
Consistent Multi-Year Performance
Multi-year averages demonstrate reliable, repeatable results across different growing conditions. The 3-year Clarion trials showed consistent positive responses for both corn and soybeans.
