Frost Management and Early Planting
One of the risks in planting early is a frost striking at the wrong time. Well, it struck and it is the wrong time for Matt's ultra-early planted beans. He talks about the application he made 48 hours before the frost struck, and evaluates the impact of near-freezing temperatures combined with high humidity on the young soybean plants.
00:00 So we're starting the morning Pretty good. Frost on top of the truck as you can see. Not as much on the bottom of the truck. 00:10 So we'll be out there around daylight, see what happens. Alright guys, we're here hopefully for the second 00:17 to the last time that, that we have this series on the ultra early planet beans. If that's the case, then we'll have this report today. 00:26 Everything's gonna go rosy from there and no more frost chances. And we're gonna cut this crop plus a another crop 00:33 maybe in October. So soybeans this morning, the lowest it got was 33. We've done some B roll and some pictures of these beans. 00:41 They do have ice on them. Right now it's seven 30. So in the last hour it's went from 33 to set to 37. So temperatures went up four degrees, sun's up. Good. 00:52 Now, you know, warm it back off. I'm not so worried about the temperature because it never went below freezing. 00:58 What I'm worried about is we have this high humidity. So it was 89% humidity here this morning at six o'clock and it was 33 degrees with 89% humidity. 01:09 You know, it's sopping wet out here right before daylight. Water's on the plant, moisture's on the plant. 01:14 Kinda like the how bridges ice before the ground does. So that plant setting up here above in the air, you know, just like a bridge is in the air, 01:22 so it's gonna catch the ice quicker than, than the warm, you know, the warmth of of the ground. 01:27 Now the warmth of the ground is gonna make a difference for the root system. So we're gonna have to see how this works. 01:32 But I've got flags out here that I put up last week on some plants that were kind of in the crook. 01:38 Uh, we wasn't sure if they was gonna come up or not. That's some of the research I wanna do is when I'm walking through a field and these beans are at a crook 01:46 and then we've gotten a rain and it gets crusty, you know, what percentage of 'em will come up 01:50 or what percentage of 'em will break their neck. And honestly the flags I put up, I didn't put up but eight flags on eight different plants. 01:58 But I would say six of them came up and they, you know, we, we've got enough population out here that if all of 'em hadn't have 02:06 come up, come up, it would've been enough. But that's another part of the research project. This is limited acres. 02:11 We do it on limited acres to be able to see how early we can go to the field. If we can get in this late February window, 02:19 we can pretty easily get a second bean crop on that acre. If we back up to, you know, my normal starting date would be 02:27 around the middle of March, March 15th, 16th based on the frost window, then normally we wouldn't be able to get 02:33 that second crop in there and you know, really have any kind of ROI to it. So that's the data that we're looking for. 02:40 And also, is there any increased yield once you go north of March 16th? I don't think there is, 02:49 but I think from an efficiency factor, if that yield would stay the same and you had a third of your bean crop planted earlier, 02:56 you know, then that spread your equipment out. But so far we're 50 50 on this deal. Last year was not a success. 03:03 The year before was a, was a very good success. So I needed this, this year to be a success to at least prove two out of three to give us some data 03:12 to go towards more of a long-term, um, uh, goal. So talking to the extreme ag group, you know, Lee Lubers, Kelly Garrett, some of those guys up the north, they deal 03:23 with this a lot more even during normal planting conditions. You know, we're outside the window of 03:27 where we know we're supposed to plant, but they deal with this a lot of times year round in the spring. 03:33 So a guy with those guys and we decided, you know, there, there's products out there, stress mitigators, there's also products out there that, 03:41 that strengthen the plant to allow it to um, take on more adversity, which would be, you know, maybe a killing frost. 03:48 So we went through the scenario, we need this on the plant 48 hours before the the weather event. 03:55 I was a little worried about coverage because most of these beans are in their uni foliate, some of them are just emerged, so they're not, nothing much is 04:03 above, you know, the uni folia. So there is a little bit of leaf surface there to take it up, you know, 04:08 and Lee said it's about the percent coverage. So if we're looking at a seedling bean versus a big bean is still the amount, the same percentage of the 04:17 solution will get on the small bean as it would the big bean based on math. So we ran two ounces of a product called shield, uh, 04:25 from integrated Ag Solutions, two ounces of mega grow and then we run an ounce of fortified stimulant fromto. We put these three products together 04:34 at five gallons an acre. Could be throwing our money completely away, but if there's a chance these beans will live, 04:40 these products will make this bean react and, and do a little better. Now the root system looks really good. 04:46 That's what's impressive to me, again, that we've talked about the fact that the infer products don't work real good in the delta, 04:53 but this is what it's looking like. You know, in cold weather I changed my mind a little bit so, you know, I think this beam needs some protection 05:00 'cause it takes it longer to get outta the soil. And we're, we were building a pretty good root system on this beam before the ole came. 05:07 So I'm very impressed with what the root system looks like. We just gotta see if we can hold this on 05:13 and keep it from dying with the frost we just had, I can tell on this particular plant that the frost has already melted off, 05:20 so it didn't stay on there a long amount of time. And that could be between that and the products we put on, it could be our savior.
