Keith Bolin of Manlius replaces Keith Dittrich, a Nebraska farmer who stepped down after six years as head of the organization.
Bolin began his one-year term this week and vowed to work on reforming policies that he says are stifling income on American farms.
Since 1978, the 43-year-old has operated the 540-acre family farm where he grew up in north-central Illinois. He raises corn, oats and alfalfa, and has an outside farrow-to-finish hog operation.
The national association was formed in 1987 and represents corn growers in 35 states.
(Manlius is a town of about 350 people, about 50 miles north of Peoria)
