Farming inputs such as pesticides and fertilizers are very expensive. A farmer wants to use the least amount necessary to do the job. Just like medicine, more is not better. Farming utilizes a technology called “precision farming” made possible by Global Positioning Satellites. This allows a farmer to know how much yield comes from each measured location on a field. Having knowledge of “yield” helps the farmer know the amount of nutrients used to make the crop.

"With a dad as a agronomist and a mom that's a great cook (although she would disagree), you can't help but develop a love of nature's complexity, being outdoors, and teaching students that food just doesn' t magically appear at the supermarket."

"I grew up working on farms in Northern Indiana and developed a real love for the land and agriculture. Few youth are exposed to farming today. I enjoy sharing my knowledge with them."
