Objective:
This experiment evaluates the benefits of adding micronutrients into a soybean foliar program when soil tests are low for micronutrients. This location has an extremely low soil level on manganese at 2 ppm. In addition to the 3 gal/A Sure-K, 1 qt of Micro 500 and 1 qt of MicroLink Manganese were added to the application. Applications were made to 15” row soybeans that were 9-inches tall in the V4 growth stage.
Conclusions:
- Both foliar programs with and without micronutrients significantly increased soybean yield over the untreated check.
- The addition of 1 qt/A of Micro 500 and 1 qt/A MicroLink Manganese increased soybean yield 1.3 bu/A over the Sure-K only foliar program.
