Purdue Extension Agriculture Agronomy Chat 'n Chew Cafe Corny News Compendium

Corny News Compendium

One of the great characteristics of the Web is its ability to serve as a repository of historical information that is accessible at the click of a mouse. These Corny News Network (CNN) Archives serve as a repository for the agronomic articles published by yours truly at the Chat 'n Chew Café since 1995, with some additional others written by some of my colleagues here at Purdue. There is value to preserving these articles because the problems and issues they speak to repeat themselves in corn fields somewhere every year. Even though you may not have seen a particular problem before, chances are that I have during my nearly 40 years of walking corn fields.

The articles are grouped by topic areas in the sidebar list to the left on large screen devices or by clicking the menu icon in the upper right corner on small screen devices. Jump directly to the topic of your choice or simply scroll down the main page and browse.
