Vertex-ST Dry combines Azospirillum brasilense for atmospheric nitrogen fixation with Pseudomonas fluorescens and Pantoea eucalypti for phosphorus availability in one seed treatment. In 2020 trials across three states, it added +2.3 to +6.0 bu/ac over untreated corn.

Kansas. Nebraska. Illinois. Wherever the trial, the roots tell the story. We’ve spent decades perfecting microbial inoculants for corn, soybeans, wheat, and more.

From root development below ground to ear fill above ground, Vertex-ST Dry is showing a visible and measurable difference compared to the untreated check. Vertex combines nitrogen fixation and phosphorus solubilization to help build better yields in corn.

Today we remember the nearly 3,000 lives lost, the families who still carry that loss, and the first responders who ran toward danger.
We will never forget.

A quarter century later, the impact of September 11 remains. Today, we pause to remember the lives lost, honor the bravery shown that day, and carry forward our unwavering spirit of resilience and hope that endures 25 years later.

Doug Kremer and Tom Proepper visited Illinois to see firsthand how our nitrogen-fixing side-dress and phosphorus response trials are progressing. Good data starts with good partners on the ground.
