Are We Applying Too Much Nitrogen?
At the final XtremeAg Field Day, Kelly Garrett and Tommy Roach discussed the future of nitrogen reduction in farming, emphasizing the need to cut nitrogen application due to both legislative pressures and environmental impacts. They talk about highlighted successful trials where nitrogen levels were significantly reduced without compromising yield, suggesting that farmers may be applying up to three times the necessary amount.

00:00 We're talking about nitrogen reduction. We're coming to you from the Temple Roads Field Day, the last of extreme Ag Field Day. 00:05 It just concluded and we're kind of standing here just, uh, catching up as you know how that works in agriculture. 00:10 I got Tommy Roach with Natures. I got Kelly Garrett, one of the original founders of Extreme Ag. 00:14 Kelly's been doing a lot on na nitrogen reduction. Uh, we are at his farm last year. We took it clear down to zero pounds applied. 00:21 We were at, uh, Johnny lls where he did a bunch of different nitrogen reduction studies. This is the way of the future, 00:26 I think nitrogen's the new boogeyman and we're gonna have no choice legislatively, regulation wise, where we've gotta reduce nitrogen. 00:32 That's kind of how this conversation began. So here's my 2 cents. Uh, yes, we are applying too much 00:39 and everybody would agree with that. The common mistake that we do is if we want more yield, what do we do? Throw more nitrogen. And 00:47 that's probably the worst thing that you could ever do. Kelly Garrett has said at least six different times in different recordings, the holy grail 00:54 of American agriculture is make more corn. The Holy grail make more corn, is of course the way you do that is put more nitrogen out there. 01:00 More nitrogen, more nitrogen. It was never bad. There's a reason it was always cheap and it kinda worked. It also had devastating impact on some of our soil biology 01:10 that we're now starting to understand. Absolutely. We did have the technology in the past to understand this. 01:16 One of the things that we're now measuring, and we've measured it because of pattern ag, is our fungi to bacteria ratio. 01:22 We would like it to be one-to-One, when we have it one-to-one, our efficiency and our nutrient conversion is terrific. 01:30 I believe. I can't tell you what it is 'cause I don't have any fields one-to-one and my highly managed high yield soils. 01:35 I've got one field that's one to 1700. I've got another field that's one to 2300 and that's in a 300 bushel environment. 01:42 Tommy, I know that you went into Texas Tech, but even, even though you understand one to 2300 ratio is a hell of a long way from one to one. 01:49 It is. So anyway, but we're still getting yield. You're still getting 300 bushels. So what gives is, 01:54 because you can still put a bunch of synthetic fertilizer out there, but seems to me that eventually something's gonna give. 02:00 So since you brought up the, uh, school, school of choice, um, I don't wanna be the chemistry geek here, 02:07 but go back to the laws of physics and it says every action has an equal and opposite reaction. Mm-Hmm. So if you're putting on 02:17 way too much nitrogen, what's it affecting? Is it affecting carbon? Is it affecting biological activity in the soil? Absolutely. Absolutely. 02:23 I want point out though, but it's not that most farmers think they're putting on way too much nitrogen. 02:28 It's only because of studies like these guys are doing where Kelly and Johnny are saying, what if I cut back to half of prescribed, remember it was 1.3 pounds per bushel 02:38 or something was the recommended not that Long ago. It takes 1.2 pounds of nitrogen to produce a bushel of corn. 02:43 I fully believe that. But we're not giving enough credit to what mother nature, it's 02:48 Soil will provide 78% of her atmosphere or something like that is nitrogen. So it seems to me that we we're going to wise up 02:54 to this someday and say, my goodness, we really Overdid that. I couldn't agree more. 03:00 We can, um, help mitigate some of this stress that, that we're causing by over application of nitrogen by looking at balanced plant nutrition. 03:13 It's no different than what we deal with than humans or, or in cattle over there. 03:18 Um, they require balanced diet. Plants require balanced diet, and when you apply overly nitrogen, 03:25 you're just throwing the whole system outta whack. We can, we can get to it with more potassium mm-Hmm. More micros. Mm-Hmm. All those factor in. 03:35 How much are we over applying do you think? I mean, is is year 2024? Somebody might watch this 10 years from now 03:42 and say like, God, they were off. I I think it might be half. I think it might be, we might be putting twice 03:47 as much as we need to be putting on. I think it's different in different parts of the country. In my soils, uh, you know, 03:53 we talked about the trial we had last year replicated three times. So I feel like it's solid data. It's our own data. 03:58 We, we thought the grower standard practice is say 180 pounds of anhydrous and we had 0 61, 21 80 and 240 pounds 04:07 of anhydrous applied through a block of the field. This is a, uh, field been corn on corn 10 years, no-till on a side hill. 04:14 This is not what you would say is the best bottom ground. And the zero was $143 loser. 04:20 But the 60 through two 40 again replicated four, three times. So 12 different blocks. Right. All yielded 2 0 9 to two 14. 04:28 So if the 180 is grower standard practice, were three x what we need to be. Right? Yeah. As in that example, well 04:34 'cause 6 6, 1 third of that 60 pounds still gave you within a stone throw of the same yield. 04:39 Oh yeah. And I'm not even gonna tell you, I can't remember to have to look at it again. But it isn't like the 60 was 2 0 9 and the 180 was two 14. 04:46 It was mixed up. Tommy, We're recording this August, 2024 and we know that farm economics are gonna be obviously on a 04:52 down slide pretty significantly since just two years ago. Is this gonna be the impetus? Is this gonna be the year? 04:57 Is this gonna, or next year, 2025, the reason where people, meaning operators, producers say, oh, 05:04 I'm gonna back off by half. Is this the year that happens? Uh, 'cause it it is just too ingrained in their mind 05:09 To, it's gonna take something really drastic. And maybe that's legislation a drastic thing. Maybe it's legislation. 05:14 Well, when I say drastic people that we had these questions today at the field day, you know, why do you do what you do, 05:21 especially with phosphorus? And they said, because granddad did it. Mm-Hmm. And that's the same thing with this nitrogen topic. 05:29 Why are you putting that much nitrogen on? Because, because The most expensive thing we're doing on our farms 05:34 today is what we always have. Yeah. So you don't think that, uh, now here's the problem, and I don't like to bring this up 05:40 and we're, we're a family show and it's don't get cussing about politics, but the regulatory environment is gonna 05:45 change and it's gonna change fast. We can look at Europe, we can look at what's happened with the European Union. 05:49 There are absolute, not say, seizures and farms, but there are definitely being huge, pretty heavy handed government controls based on, 05:57 and it's all in the guise of nitrates that could come here. It is going to come now, when, 06:03 when is it gonna get here or to what level? Right. It it's gonna get here. Regulation unfortunately is going to, and 06:09 Nitrates are the new boogieman. Am I Right? Phosphorus has been a boogeyman for quite a while. Nitrogen is the next country. 06:17 I agree It is. And you, you'd say, well, not out here in farm country. Well, I'm not. I'm 35, 40 miles from the Ohio border. 06:23 We started hearing about the algae bloom in Lake Erie, which was directly attributed to over mostly phosphates. Phosphates in northern Ohio. 06:29 Agricul Chesapeake Bay, the same one Chesapeake Bay Where we're standing right now. And then he's in Iowa. 06:34 You'd say, oh, Iowa's a huge ag state, which it is. Well, they'll never have to have the regulation there. They're 06:38 They've already had It. The water situation and the The Des Moines watershed, Webster, Webster County, Iowa. That was because of nitrates, not phosphorus. Yes. 06:45 All right. Can we, can we get by with less nitrogen and we just gotta get a little smarter about it. Absolutely. Get by with less. 06:50 And it's all about placement and time. I look at it as the same thing with antibiotic usage and livestock production. 06:57 It used to be you fling it out there, then they put it in, the tetracycline was in the chicken drip lines, uh, 07:02 antibiotic over usage and hogs. I think it's the same thing. We scream bloody murder that we can't get by without it 07:08 until all of a sudden we can't Until we have to figure it out. And what would be most profitable for you and your family 07:14 and your operation is if you educate yourself ahead of time, be ahead of the curve. Yeah. I think figure it out 07:19 before becomes a regulatory thing because you're probably overspending anyhow. So it's not only the 07:24 environmental issue, it's the economics. I agree. You can help Tommy Roach with Nature Kelly Garrett, one of the founders 07:29 of Extreme Ag named Mason coming at you from our fifth and final extreme Ag Field Day here, Centerville, Maryland at Chestnut Marine Farms. 07:36 It was a great one. You know what, if you didn't catch any of our field days, or if you only caught one 07:40 or two of them, go to Extreme ag.farm and look at the footage. We've shot dozens 07:43 and dozens of videos at these field days to bring the learning home to you. Still not as good as coming here and getting to shake hands 07:49 and really kick the bricks and do this in real time. But you know what, it's a close substitute. Check it out. Extreme Ag Farm. Till next time 07:55 or next year, Dave Mason coming at you from Maryland. I.
