As we celebrate National Ag Day, it’s important to remember Agriculture continues to be one of Wisconsin’s largest industries, contributing an estimated $104.8 billion annually to the state’s economy. One of those contributors is Wichman Farms in Appleton, operated by brothers Mark and Bruce, and Mark’s son Brad. This fourth-generation farm began in 1916 as a 117-acre farm. Today, it’s grown to 550 acres with 250 cows.
