Crop Health Toolkit: NDVI, Thermal Imaging

Using tools such as NDVI collected from an airplane, satellite or toolbar can give farmers clues about corn problems earlier in the growing season, Farm Journal field agronomist Ken Ferrie says in Episode 11 of Corn College TV Season 3.

"I can look at this same field (with) an NDVI shot and I can see the same problem areas, but now I see them clear back here in July, not in September," Ferrie says. "So I can make a visit to that field, and I can try to figure that out."

Meanwhile, thermal imaging takes a crop’s temperature and can be useful for locating insect infestations, early disease pressure and under-irrigated field sections.

"This is telling you the crop is starting to get sick," Ferrie says of maps depicting yellow and red spots where the corn’s temperature is raised.
