Just how far has precision agriculture evolved over the past 25 years? Think back to when the first commercial yield monitors began to appear.

Jeff Boyer, superintendent of the Davis-Purdue Agricultural Center near Farmland, has held on to outdated hardware and software instead of tossing them in the trash can over the years. As a result, he was able to put together a special display in the farm’s conference center that contains some of the earliest precision ag technology. Thought to be cutting edge at the time, most of these items are dated enough to be candidates for his “museum” today.

Boyer holds on to these relics because it helps him remember and explain to others how precision technology has evolved. Purdue University’s Davis-Purdue Ag Center will celebrate 100 years at a field day on Aug. 31. The history of precision technology as it changed at the Davis-Purdue Center will be one of the things Boyer discusses during the field day.

Here is a look back through history with equipment Boyer actually used.
