The Chat 'n Chew Cafe

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

About the Cafe...

The Chat 'n Chew Cafe was developed in 1995 by RL (Bob) Nielsen, Purdue University Extension Specialist, as an online source of timely agronomic information for major field crops grown in Indiana and throughout the Midwest. The Cafe was recently renovated using a more modern CSS framework, based on the open-source W3.CSS stylesheet language, available at http://www.w3schools.com/w3css If your browser has any problems displaying these renovated pages or if you have any other comments / concerns about this Web site, please contact me at rnielsen@purdue One quirk I am aware of on tablet or smartphone displays is that these dropdown menus do not automatically disappear when you press elsewhere on the screen. I am looking for a solution for this. In the meantime, refreshing the browser will remove the dropdowns.
