GROWMARK is an agricultural cooperative providing agronomy, energy, facility planning, and logistics products and services, as well as grain marketing and risk management services in more than 40 states and Ontario, Canada. GROWMARK owns the FS trademark, which is used by affiliated member cooperatives to serve more than 250,000 customers.
The GROWMARK System began in 1927 when Illinois Farm Bureau members organized local agricultural cooperatives in order to meet their growing demand for a reliable fuel supply. Soon, nine of those cooperatives combined to form Illinois Farm Supply Company, which merged with similar organizations in Iowa and Wisconsin to form FS Services, Inc. In 1980, GROWMARK, Inc. was established through the consolidation of FS Services, Inc. and Illinois Grain Corporation.
