Unusually warm weather in Iowa the second week of October led to rapid in-field drying of crops. Many farmers now find corn at 11 to 14 percent moisture content in the field. Excessively dry corn is more brittle and susceptible to mechanical damage during harvest. Dr. Charles Hurburgh notes that...
