Our Plankinton Headquarters

The history of Ag Kota Grain is nearly as old as the community of Plankinton itself.  Organized in 1885 as the Farmers Cooperative Elevator, Ag Kota Grain continues its mission of supporting regional agriculture with the buying and selling of grains while stocking a variety of products that support farm and ranch.  Ag Kota Grain invests in the latest technologies such as Internet-based pricing and grain transport systems that enhance the productivity of our customers.  Ag Kota Grain has recently expanded its service area with facilities serving the Woonsocket region.  Stop by and meet with our team to learn how Ag Kota Grain can help in your agricultural operations!
