Can a biological make up for less nitrogen in your field?
At Johnny Verell's Field Day, Damian Mason talks to Kelly Garrett and Johnny Verell about a nitrogen reduction study that showcased multiple trials assessing the impact of varying nitrogen levels and biological alternatives on corn yield.
00:00 Hey, we're talking about a nitrogen reduction study here at Johnny Verell's Field Day. 00:03 It's coming up tomorrow, and we're taking a little opportunity here to video some stuff. Got Kelly Garrett with me as well as Johnny Rell. 00:10 'cause this is a really cool thing. Kelly and I last year filmed a video around the corner from your place in Iowa, 00:15 and you've said, you know what? I believe we overly nitrogen, that we play a nitrogen that never gets, uh, up into the plant. 00:20 And Johnny is kind of taking that ball and running with it in this field day. Tell us about the trial and we're gonna 00:25 talk about his experience last year. Yeah. We got 10 different trials going down through here, replicated, and basically we go from no nitrogen 00:31 to all right here behind me where we pull out zero pounds for the entire year to 40 pounds at planting on up. 00:36 And then we actually play with different biologicals. There's three different biologicals out there that say they're able to make nitrogen. 00:41 We put out zero nitrogen and put that biological out there to see what it can give in return for us. 00:47 And we're gonna see where the, you know, see where the ROI works out, because at the end of the day, we know we can put more nitrogen a lot 00:52 of times and make more yield. But what's the ROI? So we think there's a sweet spot by visually what we're seeing out here, you know, and it, 00:58 and it actually goes in line what Kelly's seeing at his, You saw last year that zero nitrogen like this. 01:04 And if you're listening to this, um, instead of watching, uh, just, you know, close your eyes and imagine, 01:10 unless you're driving down the interstate, but if you are listening and watching, you can see behind us, 01:15 this looks like bad sweet corn that would be in Indiana after a really, really wet year. This looks like crap. 01:22 It's, it's four foot tall, it's yellowish. The ears are about the size of a, I mean, this sucks. Yeah. Zero nitrogen clearly is not the answer. That's right. Zero 01:30 Nitrogen is not bad. But you say you've got to go radical on a test before you can bring it back to what you'll flip. 01:36 You've gotta do something radical to learn anything. If you don't go low enough, you're never gonna learn anything. 01:41 On my trial, we had 0 61, 21 80, and 240 pounds of nitrogen. The zero was much like this, negative $143 ROI. 01:51 But the 61, 21, 82 40 pounds, all pounds of nitrogen all yielded within five bushel of each other. So what if I had never done the zero? That's right. 01:59 We would still be wondering was the 60 low enough? Yeah. Now we know. So you've got to do this in a trial to do this. 02:05 So I applaud Johnny for doing something radical. Yeah. But the 60 through two 40, all within five bushel. Why do you need all the nitrogen, 02:12 $4 corn, save your input dollars. Yeah. You've got a bunch of different things here. I mean, we, we've got at least 10 different, 02:18 uh, strategies here. Is it your gut? And I also wanna go to Kelly that a biological can make up for nitrogen that we used 02:26 to just pour the nitrogen to it. Yeah. Well, we're saying out here, we went and pulled the ears. Absolutely. Some of the biologicals will actually make, 02:32 you know, there's one out here that's, it says it's gonna make 40 units. It sit here and it looks as good as the 40 units that plant, 02:37 or actually a little better. So that's the good thing that we did, is we actually put the biologicals out there 02:42 with no nitrogen to see what they're gonna make per bushel by each one of 'em. And it's replicated. 'cause you know, 02:47 sometimes there's a difference. I think that's one thing that's interesting. Me and Kelly are kind of seeing the same results. 02:52 I haven't harvested, but off of what he's seen last year, you know, he's got a lot higher organic matter Right. 02:56 Than what I have. Right. And we're seeing a lot of the same results. Did you Use any accentuating products? Biologicals 03:02 I or Not? Or is it just pure pounds? It was just a pound adjustment. It's just a pound adjustment to, to test that. 03:08 And I, in my soil with that organic matter, the biological system that exists there in Iowa, that's what temple time 03:14 About. I've heard that we, we are Producing so much nitrogen Yep. That, that we have a hard time staying ahead of it. 03:20 We're more concerned about balance. I believe that eventually there will be environmental pressure and it may even be part of A-U-S-D-A program. 03:27 If you wanna get USDA batched crop insurance, you're going to back off already. 03:31 We see it in places like where temple iss, phosphorus, nitrogen's, the next boogieman. This might be a trial right now, 03:36 but it's pretty much a given. You're going to produce corn with less nitrogen five to 10 years from now. 03:40 Because either, either it's the financial or it's the actual regulation. Regulation. Absolutely. I agree a hundred percent. 03:47 We, and, and what we've done in the last five years, we were at 1.2 units of nitrogen per bushel, and now we're down to about 0.7, 0.8. Depending on the 03:55 Per bush, you're probably around that. Yes. In our high yield areas, we're only putting on 80 pounds of anhydrous, 04:00 20 pounds with the planter. So we're putting on a hundred pounds with a hundred pounds of total nitrogen. 04:05 And we're hope to produce over 300 bushel corn in those areas. But we're trying to use what's in the soil. Got 04:10 It. We are at the Johnny Rail Field Day. It actually kicks off tomorrow. We're out here pre uhhow doing this kind of stuff for you. 04:18 If you have never attended an extreme ag field day, you really should because who else is gonna go out there and let something like this? 04:23 Most field days you go to Yep. 300 bushels. S hundred bushels. We're out here showing you that if you don't put any knives on, it's gonna, I, 04:30 I don't even think I hungry raccoon would want this ear of corn. Johnny, Can I say something though? This 04:34 is the most educational ear out here. It might be the most unattractive ear, but it's the most educational 04:39 ear because we found the bottom. That's right. Yeah. Damien Mason coming at you from extreme Ag. We have field days at all the guys farms this year. 04:45 Hopefully you made one if you didn't go and check out the footage that we have shot from these field days. 04:49 So you can take the lesson from the field day home and apply it to your farming operation. Johnny Verell, thanks for hosting us. 04:54 Kelly Garrett, thanks for the information. Till next time.
