ECBEastern Corn Belt
Who operates and manages this LTAR site?
The Soil Drainage Research Unit (SDRU), and The National Soil Erosion Research Lab of USDA-ARS.
The Eastern Cornbelt LTAR sees an average annual temperature of 7 to 10 ˚C, with an average high of X˚C in July and an average low of X˚ C in January. The average annual rainfall is 760-915 mm.
