Martinsburg is a little farm town located in Northeast Missouri. Founded by William R. Martin in 1857, It is one of the many small railroad towns you can find in Audrain County. The current population is 304 people. Like many small Midwestern towns, agriculture forms the backbone of the community. You cannot take a trip down main street without seeing a line of grain bins at the Martinsburg Farmers Elevator, the St. Joseph church tower, or a tractor! Martinsburg is where Spoor Farms calls home, and we are proud of it. Next time you get a chance, make sure to swing by and stop in at one of the local businesses or to take some pictures of the beautiful rolling prairie farmland.
