Cup of Coffee

The Chat 'n Chew Cafe

Timely Agronomic News & Information for the U.S. Corn Belt


The Chat ’n Chew Cafe was developed in honor of all the small town coffeeshops where farmers and business folk have congregated for years to shoot the breeze and share gossip about corn, soybean, wheat, cows, hogs, bankers, basketball, lawyers, and the like.
In its current iteration, the Cafe offers direct access to timely agronomic newsletters from land-grant universities around the Midwest, an up-to-date calendar of major educational events around the Midwest, direct access to Purdue Extension field crop specialists and field crop Web sites. You can also access the archive of my Corny News Network articles.
