Under the FAST STOP name, the co-op runs more than 250 fuel stations and convenience stores in the Midwest. Its Seedway subsidiary sells commercial vegetable seed and farm seed for turf, and grains including alfalfa, corn, wheat, and soybeans. GROWMARK also offers fertilizer, seeds, ethanol, biodiesel, and farm financing. Its MID-CO COMMODITIES subsidiary trades grain and offers advice regarding futures and options.
