The Lincoln County Farm Center provides retail fertilizer blending services from their Monolithic Dome facility in Chandler, Oklahoma. The 75-foot (23 m) diameter by 38-foot (11.5 m) tall Monolithic Dome is divided into six storage bins where various bulk fertilizer products are stored. Blends of bulk and bagged fertilizer products — each mix custom designed and created based on the season, crop, and soil conditions — are sold to Lincoln County area farmers.
Constructed in 1978, the storage dome was the first Monolithic Dome fertilizer storage ever built. William Matthews read a story about the Monolithic Dome in a fertilizer magazine and contracted Souths, Inc. — the predecessor of Monolithic — to construct a storage dome in Chandler, Oklahoma. The finished dome sat alongside historic US Route 66 and attracted a lot of attention, leading to the construction of fertilizer storage domes all along the Mississippi River.
The six storage bins were also the first constructed using single-sided plywood forms and spray-in-place concrete to create the walls. It’s a process expanded to build Orion style Monolithic Domes and is also the preferred method of bin wall construction, today.
As one of the earliest Monolithic Domes, the air-form membrane was removed and a coating covered the dome. After 33 years, the dome was re-coated using metal shingles — in a process called metal cladding — to renew the dome in 2011.
