Residue Breakdown for Fertility Utilization
28 Oct 239 min 56 sec

Your residue holds a lot of fertilizer you’ve already paid for, so why not get it out of the residue and into your crop? The guys from XtremeAg have done a few recordings on the subject of residue management. In this episode Mike Evans of Integrated Ag Solutions joins Damian and Holganix’s Brian Mohrfeld to talk about cycling nutrients out of residue.  

00:00 Talking about residue breakdown while we're here at the Farm Progress Show, let's face it, the crops have a lot of residue. If you have high yield crops, 00:07 you probably have even more residue population, uh, spacing. The fact of the branching, I mean, all these kinds of things, 00:13 even with soybeans, now we're talking about quite a bit of residue. And residue breakdown is a very important topic. Why? Because first off, 00:19 you wanna recycle and cycle that residue back into the ground. Also, come spring you want to have good seed to soil contact. 00:26 Too much debris prevents that from happening. So it's a big topic with big crops and yeah, they're talking about, uh, reduced stature corn, but there's still gonna be a lot of residue out there. 00:38 So Mike Evans with Integrate Ag Solutions, uh, uh, working with Kelly Garrett at Garrett Land and Cattle, and then Brian Feld with whole Organics. 00:46 We have more stuff out there than we used to. And then in the old days, you know, because some of us really remember it, 00:51 I used to grow the moldboard plow and plow it under and they don't have any residue, right? Well, we don't do that anymore. 00:55 So take me to today current and then uh, we're gonna talk about some of the ways we can go about managing residue. Yeah. So like at Kelly's operation, a hundred percent no-till, um, 01:05 higher yields, uh, better genetics, better fertility programs have led to stronger plants, bigger plants, bigger leaf areas, so more residue we we're putting on the ground. 01:13 So we're always very conscious of how we're breaking that residue down. We've seen the negative effects when it comes to planting and Kelly's operation 01:21 where we reduced our stands because we had way too much and couldn't get rid of it. 01:24 So it's become a very important part of his no-till operations and more customers are one to break down the residue to use it. You 01:32 Shouldn't view it as some burden, some terrible thing. Residue still holds a whole bunch of nutrients from this year's or last year's crop. Also, 01:42 it protects the soil good for soil erosion prevention and also for cycling of nutrients. So it's not like, oh, this terrible awful stuff needs to be, 01:51 you know, destroyed. No, it just needs to be managed. Exactly. So our bio 800 breakdown is designed to put the nutrients 02:00 back in the ground. Alright, so when do I put something like this on? 'cause there's a number of products out there, 02:06 a number of biological products that go out there. I always would've thought, yeah, go out there in the spring and do this. You say 02:13 We do it in the fall. Uh, that's where we start, combine, goes through, we're spraying it on and getting this process started. 02:18 Is it, is it a single pass? Do we put this on as a single pass? A product like yours or any of the others? Meltdown breakdown, uh, bio 800. 02:24 I mean there's a, there's a, there's a number of'em out there. Do they all work in the fall? 02:31 So our by way under breakdown, we would like to put it on right after the combine. Yep. Is it a single pass or there's something else in there? 02:37 Do I put it on a herbicide to control fall annuals? You can in a burn down situation, you get out. Like I know in Nebraska the guys are doing a lot of fall burn down, 02:45 so that's a great opportunity to get it. Compatibility issues. Yeah, we have compatibility. We can put it right with anything. You can go 02:50 In with herbicide and doesn't cause a problem. Nope. Alright. Is it melted down then All of a sudden I come in the spring and it's just down 02:56 to bare dirt. What could I, what should I expect? What should I expect, Brian? Oh, for our product? Well, or yeah, I mean, yeah, 03:02 for our product especially that, I mean, we're getting it broke down. We got a couple examples over here of our breakdown. Yeah. 03:08 But we are getting a lot of it mixed back down into the dirt. All right. The person that says, I don't want to use these products. 03:15 I don't even like to go out and spray. I stick with tillage. I think the tillage is going to start to rear realize, uh, more and more. Oh, 03:22 that's kind of, uh, not the way to go. What do you think? You're the agronomy guy. 03:25 Yeah. I mean, I've got a few guys that do do tillage minimal till or whatever, and they, you still see this, the crown and especially corn. 03:33 The butts still in the ground. Yep. Uh, years later, um, you'll still, you still see stalks length of stalks in that tilled ground. 03:40 So you need to break it down just because of that. I mean, they create pinch rows issues with hair pinning and all that other stuff. 03:47 Got it. Ryan? Um, there's the low stature, short stature corn that's coming. Both the big two, uh, seed companies are touting it. Is this gonna be an issue? 03:58 Or all of a sudden are you gonna say, Hey, we got this product. And then the farmer's gonna say, yeah, 04:02 well I went from 14 foot tall corn to five foot tall corn. I don't need it. Yeah. I don't think, I don't think, I think with the smaller, shorter corn, 04:10 it's gonna be bigger around. There's still gonna be a lot of residue there. Your thought same? 04:16 Well, I look at it a different aspect. I look at it as a, that as a nutrition source. 04:21 So you got all the nutrients that you did to build that crop up that year. Yeah. You can recycle those for next year's crop and really start regenerative ag that 04:29 and with that pass and look at that application, One of the things is about the fertility that's still in, especially like we talk about corn stalks. There's a whole bunch of stuff. 04:37 There's mostly potassium that's left in there. There's, there's phosphorous left in there. There's even nitrogen left in there. Mm-hmm. Does do I lose that if I don't use a product like bio 800 breakdown? 04:48 You're not gonna lose it completely, but you're not gonna make it available for that next crop. So is there, I mean this accentuates this, 04:56 this gets it broken down and getting it going. What if I'm losing it too early? If I go out right after the combine, I spray something like this on, 05:02 do I break down and get all that nutrient into the soil and all of a sudden it's, it's depleted or leeched out by the time I need it come April, may, June? 05:10 I don't think so. I think it's a slow enough process that you're gonna retain it. I mean, phosphorus is slow to move in the soil anyways. Right? So once you get that, 05:17 it's in the soil. Potassium takes water to move. It doesn't really move a whole lot farther. So you're not gonna have it, um, go away, so to speak. And leach out. 05:26 If I see a growth in cover crop, uh, establishment through some of the things like U S D A is talking about, they're gonna encourage, subsidize, maybe even require cover crops. 05:36 It seems to me this product I might need even more right after the combine versus the old days because now I need to get seed as a cover 05:45 crop in. And I think the more quickly I can start the cycle, this. So does this play play better? 05:52 Play well play more successfully in the future? It has increase in cover crops. Yeah. So one thing with the cover crop, 05:58 if we can get that broke down and we can get some bare soil on top to get that ground heated up. Yeah. That's gonna make our You're talking spring. Yeah, 06:06 for our spring. That's gonna make our seed come up even more even next spring in the Future with more cover crops. Does a product, uh, 06:13 that causes the residue breakdown, does it have more application? Is there gonna be more demand for this five years, 06:18 10 years from now if we have more cover crops? I, I would think so. I think it's yet to be determined. Uh, but we want to break down those nutrients that those cover crops scavenge outta 06:29 the soil too. So I think, I think there's a fit in there. You're Doing, uh, 06:33 experiment and trials with organics this year at Garrett Land and Cattle. You've done other products that are used to break down fodder. 06:41 So what do you expect to see from the organics product and what have you seen in the past with other companies that we've trialed? 06:46 Well, I just, I, I want to see the tough parts of that plant starting to degrade. Yep. And, and by this time of the year, 06:53 we wanna see it pretty well from a hundred percent cover down to like a 20, 30% cover on our ground. So that's what I would want to see. 07:00 And then obviously the nutrition getting into the plant and a yield response as well. Got 07:05 It. What we, what are we gonna see? We're gonna see, uh, for our breakdown? Yeah. Yeah. We're gonna on those Field, on those fields that they're gonna use it in, 07:13 In Iowa, we're, we're absolutely gonna see to the row where you use the breakdown, you know, where it's pulling everything back down the ground and less, 07:24 you know, less cover on top. Got it. I think this definitely is a part of a new cropping system. We're gonna see more and more of as we move forward. It's just a question of, 07:32 uh, is one treatment enough? I mean, do I need to put this on the spring or we gonna find out that a second treatment has been, is, in other words, is, is would a second treatment be worth the past? 07:43 Uh, we're playing with that, uh, 'cause of so much residue in the no-till system. Uh, you still see it later in the season. I was explained earlier, you know, 07:52 I'd like to get it to 20, 30% 'cause we're gonna, especially in the corn on corn no-till situation, we get a lot of tonnage out there. So we need to keep cycling and keep rolling 08:00 It. And last question. Do we need it on soybeans or Absolutely. We need it on soybeans. We Need it on soybeans. Yep. 08:06 And, and you know, the breakdown's gonna help tie up that nitrogen that's left over. Yeah. So that's the biggest thing that I like about the 08:13 So could it, can you justify it on a price? Can you justify the price just on the nitrogen savings on a soybean application, on a after soybean application? 08:20 After soybean? Yeah. Actually with combines today. Um, or a little better. But there's still a lot of combines out there that can't spread, that chaff, 08:28 that straw out far like 40 foot ahead. They only spread at 30. So it's concentrated in more of a band. And there's issues in those bands. 08:34 You can see the waves in the field from that. Which makes me think about the next thing. Are we gonna see a day? 'cause you're not talking about very much products. 08:40 How much product are we putting on? We're putting on a half a gallon an acre. Is there gonna be a day that we can somehow do this with the combine pass so we 08:47 don't have to go out there? 'cause if I have no need to go and do a false sprayer pass that's, I've gotta fire up the sprayer and cover all those acres. 08:53 Is there a way to eliminate it? I, It's a very logical thought. 'cause there's guys, at least in our area, that cover crop with their combines, they have cedars behind the heads. Right. 09:02 I wouldn't see why it would be that hard not to do with You See, something like that. I, I think we need to start working on it now. I think it's a great idea. 09:08 Alright, here we're our farm progress show. There's all kinds of people here that love equipment. Let's go find one and come up with that idea. But in the meantime, 09:13 we know what a good idea is. Good idea for you to go and check out the stuff at farm. At at Extreme Ag Do Farm Extreme 09:19 We have hundreds and hundreds of these videos, podcasts called Cutting the Curve that I host videos from the field that these guys are shooting to help you up your farming game. It's all free. 09:27 Extreme It's a good idea for you to go there and good ideas for your farming operation. His name Brian Feld. He is from Organic or with organics. 09:35 He's also a farmer in Southeast Iowa. Southeast Iowa. Mike Evans, my buddy, uh, from Iowa who does the agronomy work for Garrett Land and Cattle. 09:43 Kelly Garrett. Next time, uh, we hope you see, come back here and see us all.
