A Henry County farmer continues to be a leader in no-till methods. Marion Calmer is owner and operator of Calmer Corn Heads and Calmer’s Ag Research Center in Lynn Center. And he says his research is independently funded.

His research work eventually led to the invention of the world’s first single-chain, narrow row corn head for 12-and-15-inch rows along with building the world’s largest corn heads.

Calmer will be speaking at the 28th Annual National No-Tillage Conference in St. Louis this weekend. His topics are improving profitability and residue management. He has presented at the conference 26 out of 28 years.
