Growth Supplement 30 on Corn in Wisconsin
Overview
A Wisconsin grower selected an area of a field planted with corn to trial Growth Supplement 30. Two applications of Growth Supplement 30 were applied via sprayer — one at growth stage V2 and the second at growth stage VT. Tissue samples throughout the season showed the increased nutrient uptake in the sections of the field treated with Growth Supplement 30. But the real results were in the harvest numbers when these same areas yielded 3.31 bushels per acre more than the control areas.

The Results
Yield Summary
The areas treated with Growth Supplement 30 yielded 3.31 bushels/acre more than the control acres.
Key Findings
This trial had a 3.31 bushels/acre yield response
This location experienced much higher than normal amounts of rain during the Mid-June to Mid-July period which led to a projected 30% yield loss.
The tissue sample charts demonstrate individual nutrients that experienced positive uptake levels
Summary
The application of Growth Supplement 30 helped to improve nutrient uptake in corn leading to an increase in bushels per an acre harvested.
Products Used

Growth Supplement 30
Growth Supplement 30 is a foliar applied nutrient stabilizer. It stimulates plant metabolism, transports nutrients in plants, dissolves macro and micro elements, and enhances cell division and elongation. Containing plant derived fulvic acids, Growth Supplement 30 is compatible with most conventional herbicides.
