Spatial variability of ethanol yield from corn grains were investigated in a field with about 50 ha in size. Corn samples were collected in both 2006 and 2008. The relationships of ethanol yield with soil physical and chemical properties, and terrain attributes derived from the elevation data were also investigated.
