The first fertilizer storage and a barbed wire plaque The first Monolithic Dome fertilizer storage. Built in Chandler, Oklahoma, 1978. After 35 years, the dome was looking a bit worn. In the 1970s we used to peel the Airform membrane and coat the dome. Turns out to be cheaper and better to leave the membrane on. Stainless steel cladding renews the storage for another 50 to 100 years. The barbed wire plaque made by the motel owner. Inside the 105-foot diameter fertilizer storage in Oskaloosa, Iowa. One of many fertilizer storages built along the great rivers in the central U.S. Lincoln County store built by Nelda Matthews. Inside the new Lincoln County story.
