Agronomy and Applicator Challenge


Test Your Knowledge — and Win Cash!

The Agronomy and Applicator Challenge takes place each year at Ag Expo and is your chance to win cash prizes (and maybe learn something along the way)!

Form a team and visit participating booths to answer industry-related questions. There are two competition categories: Agronomy and Applicator. The Challenge is open to all employees of Dealer and Branch members of the South Dakota Agri-Business Association (SDABA).

Join the Winners Circle!
