Established in 2013, Mound City Ag opened as a small farm and ranch store partnered by Earl Nation, Myrl Nation, and Chad Krull in an effort to support the needs of their own farm and ranching businesses but grew to include support for their local community and surrounding communities in the Mound City area.

Mound City Ag primarily stocks Purina® and ADM® but also provides a selection of other feeds. They offer customized spraying, fertilizer spreading, and the buying and selling of grain.

Mound City Ag is a proud supporter of their local school, FFA kids, and 4H Clubs.
