JANUARY 1, 2018

Ag PhD has officially announced the company’s first-ever float in the 2018 Tournament of Roses® Parade. The float, Salute to Farmers, brings a whole new meaning to “Making a Difference”.  Who makes more of a difference than farmers?  Without farmers and the food supply farmers produce, none of us would be here.  Farmers work tirelessly to feed our growing world, and they do a fantastic job.  In the United States, for example, we have the healthiest, most abundant, safest, and cheapest food supply in the world!

And that’s all thanks to farmers!
