I had an interesting development happen this week regarding some recent imagery. Most of my clients know that imagery is available them upon request providing I meet the minimum acres required for a flight. This is 1 meter resolution imagery so fairly fine. The image included here was very interesting…

This is a corn field (no-till) of a client that shows a striking line of variation down the middle. Now for those not familiar with growing conditions this year here in the Saginaw Valley, getting things planted was quite a chore. Rain delays, temperatures etc. Most growers tried to piece their plantings in between rain events and it was not easy. Conditions were anything but ideal. In the first part of June, about 3 days of rain delivered somewhere between 6 and 14 inches of rain, give or take,

First, ┬áthere are two varieties in this field, second, the west part where greener in color was planted about 3 days later and that is also the variety split. I would suppose, with you, that the first inclination is that variety is the reason for the difference on the east, and it is not going to be near as good. However i would lean toward the variety in this case having little to do with it. The east side is showing poor plant health, if conditions on both halves were identical then regardless of variety plant health would be similar and therefore little difference in the NDVI. But conditions were not the same as the west side was planted later when soil conditions were more favorable and because so, was compacted less, and suffered less stress from the excessive amount of rainfall received. Now we intend to yield check to note the difference. But I guess the point is that sometimes imagery can teach us things in a more dramatic fashion then not have the imagery at all. If there is a large difference in yield here, we may not be able to say it was because of variety alone. That would not be accurate and may lead us to poor decision making and that’s the value….
