USA 500 Provides a Good Start for a Great Finish
Mar 24, 2026
A great finish often requires a good start. When it comes to yield potential, anything you can do early in the season to give your crops a head start can pay literal dividends in the fall.
Enter Rosen’s USA 500, a Universal Starter Additive (5% Nitrogen, 6% Zinc) that can be mixed with both 10-34-0 and 7-23-5.
“Simply put, USA 500 protects yield potential and profitability,” said Christ Schmidt, Federated agronomy sales rep. “It reduces the negative effects of cool early-season stress and allows the plant to uptake maximum nutrients during a critical crop stage.”
Applied at a rate of 48 oz/acre, USA 500 provides 1 QT of 9% EDTA-chelated zinc and phosphorus protection.
Additionally, USA 500:
It’s easy to use, too. Excellent storage properties allow for premixing USA 500 with your liquid starter without concern of the product coming out of suspension in your storage tank, which makes planter applications smooth and simple in the field.
“Early spring is an excellent time to accept your liquid fertilizer deliveries,” Schmidt said. “By receiving your orders early, you are ready when conditions allow for your planter to hit the field and keep our storage tanks full to meet the demands of the spring rush.”
