Tanner Johnson is a first-generation farmer from Prairie Farm (Barron County) in northwest Wisconsin. He has been involved with the Wisconsin Soybean Association since 2017 when he graduated from the DuPont Young Leaders Program. Tanner was elected to the Wisconsin Soybean Association board of directors in 2021 and currently serves as an at-large director. Johnson was elected to serve on the American Soybean Association board in December 2022 and serves on the regulatory committee.

In addition to soybeans, he is involved in the production of corn, winter wheat, alfalfa hay, and various cover crop species in a long-term, no-till environment. Most soybeans produced on the operation are food-grade soybeans and are primarily exported to Southeast Asia for human consumption.

Outside of crop production, Tanner owns and operates a Pioneer Seed agency and agronomy consulting business with his two business partners. Their primary business focus is helping farmers become more profitable and productive in a sustainable manner.

Tanner is a 2016 graduate of the University of Wisconsin-River Falls with a degree in agricultural education and a minor in food science. He is a past noble ruler of the Alpha Psi chapter of the Alpha Gamma Rho fraternity. Tanner married his wife, Brittany, in February 2023.

Johnson credits his mentor, Andy Bensend, for encouraging him to get involved in the soybean industry and to further pursue his passion and interest in agricultural policy.
