Every year, Wesmar Seeds does extensive trialing on their demonstration sites providing visitors to these sites comparisons between varieties of soybeans and corn, comparison and testing of numerous seed treatments, population trials, and planting depths. These sites are open to the public for viewing and used extensively during plot tours and customized guided tours. Field size testing and replication is done in other sites in cooperation with Wesmar Farms to provide additional agronomic information for the advantage of customers' planting decision making.
