Using aerial photographs taken from airplanes, farmers nationwide who've adopted precision agriculture techniques can get detailed overviews of their croplands to see which plants look healthy and which don't.

Agricultural Research Service research leader Johnie N. Jenkins, at the agency's Genetics and Precision Agriculture Research Unit at Mississippi State, Miss., heads a team of ARS scientists developing a high-speed wireless networking system. It will allow farmers to download aerial images via the Internet onto their personal computers, laptops — or even better, their PDAs (Personal Digital Assistants) — in a cost-effective and efficient way.
