Johnny Verell and Brian Adams deliver the results of a residue management study they conducted last fall.

Part 1 is available here:

00:00 Johnny Rell with Extreme Ag. I'm in here today with Brian Adams. We came in today to weigh the residue. 00:04 You know, we talked about this residue study we did last fall. We showed y'all collecting all the data. 00:08 We had a little rain today, so we came in and weighed out the results to see where we are. And we'll let Brian talk 00:13 a little bit about what we're seeing here. So, Uh, Johnny's holding, um, the untreated these bags, I'm sure this video looked probably pretty similar, 00:21 but we extrapolated this out to how much residue per acre we would have. And on the untreated check, Johnny, if I remember correctly, 00:28 we come up with about 6.94 tons of residue per acre on the surface of the ground. We had several different treatments. 00:34 We tried here on one of 'em being what we affectionately caught Uncle Bob, which is North Deltas Coral. 00:40 We had excavator from Maris Stim. Yeah, we had Uncle Bob at a two x-ray. And then we had Uncle Bob mixed with some enzymes, 00:47 which was, uh, one pound of Upshift C from Maris. Stim saw a really good reduction across all products. Um, Johnny, as far as that went, I mean, what do you think? 00:56 It all looked pretty equivalent. Didn't, regardless of what it was, There was just a little bit of difference in 01:01 between each one, but really not enough to matter as far as it could be. One piece of stalk really made a difference, right? 01:06 What was crazy is, is the results were the same on all products. So what that taught us was, is putting out a two x-ray. 01:12 We didn't gain anything. That's right. We added enzymes thinking that was gonna help feed the microbes 01:17 and speed up the biology and breakdown process that didn't add anything either. So the takeaway from it is, is we saw great results. 01:24 What, what exactly did we see? So, So what we saw was, um, like I said, an untreated check. We extrapolated that out from the per unit area. 01:31 We collected to a four acre at 6.94 tons per acre. And I'm gonna shoot from the hip on this last one, but I do remember it was a 38% reduction in actual 01:41 dry weight of residue. So that come out to like, I think it was 3.88 or something like that. So a pretty significant reduction. 01:48 Again, that was across all treatments. Just like Johnny said, the, the addition of other things really did not seem to help. 01:54 Uh, just as long as we had a, a reputable weld on stubble digester, it seemed to certainly do the job when it was applied last 02:01 Fall. And the only thing we saw that really helped with the process is where we applied all these products last fall and we actually ran a vertical tillage tool 02:07 to incorporate a little soil top the residue. That's the only thing that sped up the residue breakdown any, any more than what these products did themselves. 02:14 Yeah, and I think it's fair to say too, vertical tillage has become by a very popular catchphrase. Johnny is using a, a south for Johnny. 02:21 What model is that? South. It's 2200 South. So it's the 2200. Understand that thing doesn't, it is not, it's leaving 70% 02:28 of the residue on top of the ground. That's, it's a very, very minimum tillage process. I would say. No deeper than two inches even. 02:37 Yeah. Um, we, for sizing, they're trying to size the residue and try to get that soil contact or at least get it to lay on the ground. That's 02:43 Right. And it doesn't look in the, in the fall, you know, when it rains down here in the south all winter, 02:48 it doesn't look like a mud hole out there. It still looks like residue on the ground. You can tell a tillage pass has been performed, 02:53 but, um, certainly maybe not as effective as a turbo till as far as incorporating the ground 02:58 completely turning it over. But that's not what we're asking. That Southford does a great job sizing that residue. We'll 03:03 Do another video probably September, October, talking about yield, see if there's any yield differences where we've applied the different products, 03:09 especially against the check where we didn't do anything last year. We had great results, I think on soybeans, on our farms, 03:14 about three bushel where we ground up wood digester on the previous year core stalks. 03:19 So we'll see what it is this year. This this far went back into core And just remember to you, the goal of this is as 03:25 that residue breaks down, what you're really looking for is release of your MPK, your micros and all that, trying to get that back into soil solution. 03:33 Making that plan available on a budget gear like this, you know, wherever you can save money, whether that be dry fertilizer, whether 03:39 that be even liquid fob feeding, Johnny, you know, as well as I do, the more, the more fertilizer we can get back out 03:45 of our stove from last year, the better. All four all gonna be Absolutely less residue. 03:49 Easier to plan also. That's right.
