Yeah.
5:23
Yeah.
5:24
So really, really tough.
5:26
You know, those areas where water got above the ear were the worst.
5:29
And that's kind of expected.
5:31
A lot of the ears were.
5:34
rotting, you know, had premature sprouting, you know, just a lot of issues.
7:31
I've been seeing some... pictures floating around social media of of the uh the ear of corn and it looks like looks like a dumbbell you know i go out there do some curls yep because it looks okay on the ends but the middle of it it's just it's gone yep and a lot of folks saying i haven't really seen that around here but some other folks across the country i saw some folks from nebraska be like oh it's fairly common around here we see it but here in indiana i've never seen anything quite like that

Well, I think it's, first thing we found out is very complex, right? Um, and what we found is that wildfire smoke can have, one, can have negative impacts, and the negative impacts is that it can reflect sunlight, it can reduce solar radiation, photosynthetic active radiation
5:09
radiationAnd that can potentially translate to lower photosynthesis rates in the crop, and, and that can be detrimental to the crops.
5:16
But if you move it to the flip side of that is that we actually see positive, um, impacts and, and kind of some ways that, that wildfire smoke can positively impact the crop is that one, you know, not only can it reflect sunlight, but it can actually scatter sunlight.
5:30
And we see what is known as a diffuse fraction of the photosynthetic active radiation, which is a fancy word to say it actually scatters light, and when it scatters light, um, it actually improves light use efficiency, especially in crops that are a little bit taller and multilayered canopies like corn, where it basically scatters the light and then the light penetrates better in the canopy.
5:51
Um, there's actually been some work out of California where they look at, you know, wildfire smoke and its impacts on forests, and they found that some of the forests actually have higher photosynthetic rates after wildfire smoke, and they kind of attribute it, uh, to kind of the improved photosynthetic efficiency and light use efficiency.
6:08
Um, another aspect of it too, and, and probably this relates probably most to, to Canada, right, is, is the differences in temperature.
6:14
Um, so, uh, when that wildfire smoke comes in, yes, it can reduce sunlight, but it also reduces air temperature, um, and it can reduce air temperature pretty significantly.

Are, are those potentially impacting how the corn plant performs?
