How to Prevent Potassium Deficiency in Cotton Crops?
20 Aug 245m 22s

Matt Miles from XtremeAg talks about a significant issue: potash deficiency in cotton crops. He talks to Tommy Roach about the effectiveness of using potassium acetate as a highly soluble and plant-available source of potassium, which has been applied consistently throughout the growing season

00:00 So guys, we got Mr. Tommy Roach down here today, all the way from Lubbock, Texas. And if you know anything about Lubbock, 00:04 Texas, that's cotton country, Right? Cotton capital of the world. So we're in Mr. Tommy's probably favorite crop 00:10 that you, that you deal with. You know, I guess I'm the only extreme act guy that has cotton. 00:14 Yep. Cotton's a whole different beast. Well, there's just not a lot of cotton grown except for in certain areas. 00:19 Right? So what we've been dealing with here this year, late in the year, it's potash deficiency. That is something that happens in cotton a lot of times. 00:27 But we haven't seen this at the severity that we've seen it this year. We are actually standing in Mr. Tommy's plot. 00:34 This is a full nature's program. Everything he told us to do, we just said, yes, sir. So tell us why we don't have potash deficiency here. 00:43 If you think about potash sources that are available to use as fertilizer, everybody goes straight to KCL, dry, very insoluble. 00:54 You gotta have moisture, you gotta have rain. And it takes a while to become plant available. So what we did here in this is every time he goes across it, 01:05 whether it's fungicide, plant bugs, you name it, we're putting in potassium acetate, which is highly soluble, highly available, plant available. 01:17 Potassium. And you can look out through here, we don't see any potassium deficiency. When you think about peak demand in, in crops, 01:25 it doesn't matter if we're talking cotton crop, soybean crop, corn crop. You have nutrient demands. 01:33 And in the case of cotton, peak demand for potassium uptake is at peak bloom. And if you look at corn, potatoes, cotton, 01:45 there is no way a plant can physically keep up with how much demand is, is being expressed on that plant without all your feeding, 01:55 without supplementing available potassium in some form or fashion. It's not about what people think of as 02:02 the only potassium source that's out there, which is dry KCL. We spoon feed the plant 02:08 and at least right now, we're able to keep up with what this crop has been demanding. And that's a pretty big deal 02:15 because I would say over 50% of the cotton grown in the United States at some point has a potash deficiency. 02:23 Oh yeah. Or a K deficiency, you know, and, and you've taught me one thing, you know, the potassium acetate is, will get into the plant. 02:30 You know, they will used to, everybody thought the foer was a snake oil. Right. But we're starting 02:34 to manage plants rather than manage acres. I can have a, I've got tons of potash in this soil Right. Or tons of K in this soil, 02:42 but I'm not getting it in the plant. Right. You know, those spots we looked at while ago that are deep red, dark red cut out, completely gone. 02:48 It has the same amount of K levels in the soil as this does. But the actual fos 02:54 and the things we've done to, to keep this going at peak bloom, this shows you the Difference. I mean, so people 03:00 historically, they know that they're gonna have spots in the field. Mm-Hmm. And even though soil tests may say that 03:08 you've got enough potassium to grow two bell three be cotton or 250 pound, 250 bushel corn, that, 03:18 that soil test report does not accurately reflect what is actually available to the plant. So you need to always be thinking ahead 03:29 and even though, even though a piece of paper says, I've got enough, you need to be thinking ahead because potassium is the uber nutrient. 03:36 It moves everything else around the plant. And the key goal is to keep plant running when it's a hundred degrees 03:45 out. And that's what the goal is. Yeah. Because you're sweating now. So it's, it's, it's seven 20 03:49 and it's still probably, the heating index is over a hundred right now. I'm Not used to a humidity. 03:53 I'm used to a climbing. So, question for you. We're doing soil samples, right? Our soil samples. When this technology we're using today on 04:00 soil samples, when did that start? Long time ago. 50. That's, I'm saying It's been the same thing For a long time. 04:07 So what, how, where do we go from here? Where, so we're using 1950 technology to pull these soil samples. 04:15 Is there any kind of scientifically a new way that we can do this to make it better? You know, 'cause we're growing at double the yields. We 04:22 Grew these Yeah. So, so we, we talk about sap samples. Mm-Hmm. Kelly's starting to do, i, I don't know if it's a new 04:27 technology, but that's something new that people have started using. One thing that varieties are doing now is they're able to 04:39 utilize nutrients more efficiently early in the season. But because of yield demand. Mm-Hmm. You need to apply more nutrition at the tail end 04:48 of the season versus at the Front end when the demand curve's there. Exactly. And that's on almost every crop. It is. It is. 04:54 You know, the demand curve's not front loaded at the beginning. No. You know, we've always tried to 04:59 spoon feed our potassium, you know, into the plant. Right. But it looks like some of the spots we flew over 'em today coming from Johnny, 05:05 Johnny Verell's Field Day. And I've got some pretty severe potash deficiencies, but I don't have it here. 05:10 So whatever we're doing here, we got the cotton king here showing us how to do it. And it looks really good. 05:15 It does Appreciate you.
