Helping our farmers get the most return on every acre is accomplished through many strategies and tactics. One of those tactics is helping you decide the right seed to fit your operation. Central Ohio Farmers Co-op, Inc. is fortunate to have strong products that we stand behind. We are excited that we can offer an expanded array of seed options for growers. COFC has partnered with GROWMARK, Inc. (a regional cooperative) to bring multiple lines of seed to all of our locations. Seed from familiar names like DEKALB®, Asgrow® and NK® Seed will be available at our five agronomy branches as well as GROWMARK, Inc.’s own proprietary brands, FS InVISION™ and FS HiSOY®.

We strive to provide growers with the best seed available, but to also offer choices. Having multiple seed traits will allow our agronomists to place the right seed in the right fields for our members. Having our seed businesses aligned under the Growmark umbrella also allows us to provide better service though inventory sharing and more efficient use of our seed treating systems. Our agronomy branches have the ability to custom treat your soybean seed with fungicides, insecticides, and innoculants.



For Your Farm, COFC will work with you to help manage your commodities and risks to achieve success in a diverse, global marketplace when it comes to storing and selling your grain. See our homepage for grain hours.


We offer a wide variety of bagged feeds for many different kinds of livestock and seasonal feeds are available for your 4-H project needs. Every animal, from large cattle to the songbirds in your backyard, can benefit from our bagged feed. If you require larger quantities of feed, we have custom feed grinding.
