The Importance of Late-Season Soybean Nutrition
Importance of Late-Season Fertility: Despite appearing mature, soybeans at R4 can benefit from additional nutrients to maximize pod development and overall yield. What are the crucial aspects of late-season soybean nutrition at the R4 growth stage? Matt Miles and Tommy Roach discuss the vital practices for maximizing yield and ensuring plant health under challenging conditions.

00:00 So we're at Matt Miles Field Day in Arkansas and we're asking the question, what does this soybean plant at R four still need, if anything? 00:07 Uh, Tommy Roach here, along with our man Matt Miles. Why do I need to do anything? A lot of growers, let's face it, Matt are going to just say, yep, 00:13 that soybeans made it needs another month or so and it's gonna be time to harvest him. Am I right? Well, we think we can do a little bit more with it. 00:19 I mean, you know, there's a lot of bloom still left on that plant. A lot of things that we can affect. 00:23 We're working with the late season fertility. When I say late more in the R five stage, we put a heavy load on here at R three. 00:29 That's kind of our magic button that we push is R three. So what you're seeing on this plant now is basically the 00:35 reaction from what we've done two weeks Ago. Tommy. I said when we came over here and looked at it, I said, I don't know. 00:40 These beans look like they're, they're about made. All they need to do is just fill out the pods and, and, and dry down me about late season nutrition. What's it 00:47 Need? So the key right now is to hang on to these blooms that you see. Okay. That Right there and every, 00:52 like yesterday the heat index was 110, 115 Actually It was 13. Yeah. Today. Today it rained. 00:59 So it's really nice and cool. But the key is to, to keep these blooms instead of shedding 'em. So you can eventually make, make these pods, these three, 01:08 four beam pods that you see. I see. I counted about 12 blooms that don't have pods attached to 'em. 01:12 So are they all gonna make it? And then would they, if they didn't have late season nutrition? 01:17 I, I think it takes, I think that this plant at this stage needs everything. It needs to be happy. Now the heat is kind 01:24 of reacting to that. We can still take a bean in a hot temperature and make it do things that we can sometimes can't with corn, 01:32 One thing that we talked about, Tommy, is it gets very, very hot here. We're, we're almost the, 01:36 is almost July here as we're talking. Right? And in my part of the world, the Midwest, you know, we get really hot in July 01:41 and we get some really cookers in August. The plant's doing all, it can still survive. Can the plant take up nutrition when it's in survival mode? 01:48 That's gonna be one of the, I'm sure of you right now is asking that question like hell, that soybeans not gonna take up any 01:53 nutrition. It's just trying to live. The key is not so much daytime temperature, but the key is nighttime temperature. 01:59 'cause the plant needs time to recuperate at night and without that it doesn't matter what you're gonna, what you feed it. 02:04 It's got to have recuperation. Your 0.2 years ago when I came here for the first time, you said, Damian, we, you know what happens around here. 02:11 We don't ever get those athletes a chance to come in the locker room and rest. And that's what you're talking about. You said when it's 02:16 still 90 degrees feel like temperature 95 degrees at midnight, one, two in the morning, these plants don't get shut down. 02:21 How does late season nutrition help that? Okay, so how does it help an athlete that's worn out? So if you give him vitamins and a Gatorade 02:28 And you give Him a Gatorade and maybe you give him an iv, you know he's going to, he may not be at his top performance. 02:34 Okay. But he can do that during the air. You know, he can survive longer than a guy. Don't get any better. 02:37 Survive. So you're not in the camp that says this plant is just so worried about survival. 02:40 It won't take up nutrition. You think it does take up nutrition even when it's hot and punishing. Two then Some of these guys temple are getting 02:46 packing on more bushels. Yep. At that R five stage. Yep. You know, we struggle a little bit more with 02:51 that just 'cause of the temperature. There's a, you know this, this plant's fairly young and you see the four beam pods on it there? Yeah. All 02:58 At the bottom. We still got a lot of blooms up top. It can be four bean pods. Alright, get me outta here. Tell me about the nutrition. What's the program 03:03 that we're doing late season on this plant to get those, to get those blooms up there to become four bean pods. 03:09 So even at this stage, the common misconception is that it doesn't need potassium, doesn't need phosphorus. Doesn't need boron, even nitrogen. 03:19 'cause Matt averages, you know, 80, 90 bushels and you need, even though it's a legume, It might need some nitrogen once you get over 03:25 certain bushels. Even a soybean needs nitrogen. Absolutely. Absolutely. I mean you can get in that 70 range, 75 probably 03:32 Mrs. Range. Once you get past the north of 75, you need a little bit more nitrogen. Now do I apply that here? I use a lot of litter. 03:40 I don't count that nitrogen in anymore. Okay. You know, we're actually applying nitrogen to these soybeans every year. 03:44 Okay. So the last couple things you're gonna do on this, you're gonna use a white drop is 03:48 how you're putting on or you're put on foliar. This Is fo like the late stages, like you're in right here. It'll be a foliar. Okay. Before it gets canopy closure. 03:55 You, he runs a wide drop and I would advise running a wide drop and that's something people 04:00 When, when the plants are ready bitty. But now you're going on, you're gonna foliar this and you're gonna put in that is that the 04:04 Last pass we made was a little, little round R three and we'll kind of analyze the weather and see what the temperatures are. 04:11 If we do anything later, we're going at least have some plots doing that. 'cause there's a lot of guys in areas that are not here 04:17 that are making seed weight if nothing else, right out of these extra fos. Okay. And so an extra, I think 04:23 There's possibilities. It's just sometimes that it, it, the heat of getting your way Least season nutrition pass cost you 15, 20 bucks. 04:28 Yeah. And you're, that's a bushel or two bushel. The it says Probably worth it. It could be very 04:33 complex. Keep it simple. We're talking about LA season's nutrition, your soybeans with nature. 04:37 Stay tuned. We're at the one of the plots here at Matt Miles Field day. You know what? We did five field days this year in 2024. 04:43 We have great information, so I encourage you to come if you haven't been to one of 'em already, we've got two in August, August 8th and August 22nd. 04:48 Join us please. All are welcome. We welcome to be there. Damian Mason with XT Extreme Ag.
