Leftovers From the Chat 'n Chew Cafe

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

These articles were archived from the main dining room of the Chat 'n Chew Cafe. Like most leftovers, they do not retain their freshness forever. Consequently, you may encounter articles with dead links if the Web hosting organization decides to change their Web file directories or servers. My apologies ahead of time, but I do not have the resources or time to preserve these links ad infinitum. ____RL (Bob) Nielsen, Purdue Univ.
