The Drummer soil series was designated the official state soil of Illinois in 2001 to recognize its value to agriculture and the overall economy of the state. Drummer soil is deep, dark black topsoil named for Drummer Creek (in Drummer Township, IL).
Drummer soils are the most prevalent soils in Illinois (occuring on more than 1,500,000 acres in northern sections of the state). These prairie-derived soils are also the most productive soils of Illinois - corn and soybeans are the main crops (popcorn is the state snack food). Each of the United States has selected a state soil and twenty states have recognized a state soil as an official symbol.
