Farming Podcast | Calcium Deficiency in Crops | XtremeAg
In this episode of the Cutting The Curve farming podcast, the spotlight is on calcium deficiency in crops, a yield-limiting yet often overlooked issue in row crop systems.
Calcium plays a critical role in nutrient uptake, plant cell strength, and nitrogen efficiency, but its availability is frequently restricted due to its double positive charge and dependence on mass flow, particularly in dry conditions.
This episode explores how multi-pass strategies using in-furrow and foliar calcium treatments—often up to five times per season—combined with calcium acetate and nutrient synergy (especially with boron) can dramatically improve results.
The discussion highlights why growers should reallocate nutrient budgets to focus on micronutrient balance, with validation through SAP and tissue testing showing strong returns.
It’s a real-world approach to optimizing crop nutrient availability, improving plant strength, and driving better ROI per acre.
Key Takeaways on Emerging Farming Trends
Calcium Is Essential Yet Often Misunderstood
Commonly mistaken for a micronutrient, calcium plays a critical macronutrient role in plant structure and nutrient transport.
Soil may contain high calcium, but it's typically unavailable to the plant.
Mobility & Timing Are Major Barriers
Calcium is immobile in soil and travels only via mass flow, making drought and placement significant challenges.
Dry calcium forms and untimed applications yield poor uptake results.
Multi-Pass Strategy for Maximum ROI
Kelly Garrett applies calcium up to five times via in-furrow and foliar passes.
Calcium acetate, paired with boron and SAP testing, enables targeted and efficient application.
Balance Is More Than pH
Fixing nutritional imbalances rather than chasing pH leads to real improvement.
Misapplied lime and excessive nitrogen often exacerbate calcium issues.
Increased ROI with SAP-Driven Application
Targeted calcium + boron applications validated with tissue testing deliver measurable return.
Enhanced Stress Resistance During Drought
Mass flow limitations are overcome with foliar strategies, especially during dry growing seasons.
Improved Plant Health and Structure
Calcium fortifies cell walls, enabling higher plant integrity and disease resistance.
Fertility Cost Reallocation
Reduced nitrogen and phosphorus inputs allow reallocation of dollars toward more impactful nutrients like calcium.

00:00:00 Are your crops deficient in calcium? I'm guessing they are. My guests are gonna talk about that, how you can get calcium into your plants. 00:00:07 It's basically a how to guide for one of the most important micronutrients in your farming operation. 00:00:12 In this episode of extreme Ag, cutting the curve, It's extreme ag cutting the curve podcast, cutting your learning curve, 00:00:19 and improving your farming operation every week. This episode of The Cutting the Curve podcast is powered by Nature's bio kay technology delivering enhanced nutrient 00:00:28 cycling, greater plant health, and elevated stress mitigation leading to increased crop yields. 00:00:33 Visit nature's dot com. And now let's get ready to learn with your host, Damien Mason. 00:00:41 Hey there. Welcome to another fantastic episode of Extreme Ice Care, the curve. I got a great one for you. Today we're joined 00:00:45 by Nature's Tommy Roach, friend of the show, uh, awesome, uh, agronomic expert. 00:00:50 I called him that once in an episode of the Grain ring and a couple people like looked at and said, what? Anyway, he is, he's gonna talk to you about one 00:00:56 of the most important micronutrients that you probably are, uh, deficient in. Um, Kelly Garrett says he has never taken a sample on his 00:01:04 crops that was not deficient in zinc and in calcium. And it's not because his soil lacks calcium. We've, we've talked about this 00:01:10 before, at episodes up at his farm, the field right behind his house as buku amounts of calcium. That's a French word, which means a lot. 00:01:17 Anyway, he's got plenty of calcium, but getting it into the plant is the struggle. We've covered this in different, uh, angles. 00:01:25 We're gonna cover right now as a how to guide. We're gonna start off by telling you why calcium is important. 00:01:29 Why is calcium important, and why do plants struggle to get it into their system? Tommy Roach, 00:01:36 First off, a little correction. Calcium, last I checked is a, uh, macro or a prime or secondary nutrient, not a micronutrient. 00:01:46 Okay, just thought I'd get that outta the way. Kelly says there's actually four to five degrees, and we used to just say macro micro Kelly. 00:01:54 What do you say? You say that there's, there's the macros of all macro nitrogen, and then go from there. 00:02:00 There's a macro, you know, you have the major macro of nitrogen. This is how a farmer thinks it's incorrect, 00:02:05 but a farmer thinks you have nitrogen, then you have phosphorus and cows, uh, phosphorus and potassium, maybe sulfur. 00:02:13 Then the third level, you're gonna have sulfur, and they'll talk about boron, they'll talk about zinc. That's it. Then the fourth level is everything 00:02:21 else I have gotten. So I don't even like the term macro and micro, because the implication is that the macro is more important. 00:02:29 Yep. They are all important, and I would tell you, in my opinion, they're all equally important 00:02:33 because we we're leaving money on the table. We're not raising a good crop without them. I understand the macros, it takes more of them, 00:02:40 but, uh, to imply that they're more important, I really struggle with Yeah, that's that's a neat one. 00:02:45 Uh, because it does, it's almost like you diminish it by calling it a micro. Yes. But, you know, selenium is a micro to our bodies, 00:02:54 but I'm sure that if you don't have just the little dose that you need, then I 00:02:57 don't know, you get scurvy or something. I, I know I'm mix. I know I'm mixing things up there. Tommy, you don't really get scurvy from no selenium. 00:03:03 It's, I think it's a vitamin C issue. But anyway, let's get back to it. Thanks for me. Sounds good. What do you say, where does calcium fit in? 00:03:09 It's under NP and K. Where is it? Is it right there with sulfur? It's ironically we don't even talk much about calcium in 00:03:17 what I would call cmo commodity row crops, uh, corn, soybean, wheat. Yes. You hear about it in calcium, in, uh, cotton. 00:03:26 Matt talk about it. You hear about it in, uh, fruit and vegetable. I mean, apples commonly get bitter pit 00:03:34 because of lack of calcium. You get blossom in rot because of lack of calcium and tomatoes and peppers. 00:03:43 But unfortunately you really don't hear about it in cotton and soybean. Now, is it a problem? I think it is a problem, 00:03:51 and it's probably a, it's what I would call a hidden hunger. You don't see symptoms of deficiency, 00:03:58 but if you add more calcium or figure out how to get more in the plant, we see a, we see a benefit 00:04:07 Why plants need it. And then you, we already established that most crops are deficient in it. 00:04:13 Is that, is that accurate to say most crops are deficient in it? Uh, yes, In my opinion they are. Yeah. Yeah. 00:04:21 And Tommy has seen way more samples than I have, but in my opinion, they're, I mean, you, you wanna know why plants need it. 00:04:28 Of course, we all want strong cells in case of corn. Uh, that uses a lot of nitrogen. Uh, calcium and nitrogen go hand in hand when it, 00:04:39 when it goes to corn. And another micronutrient that is needed for calcium is boron. 00:04:47 You go to the world's largest calcium, uh, boron deposit in California, guess what comes along with the boron? 00:04:56 It's calcium. They ride together in nature and they ride together in the plant. All right. So we've talked about this before. Yeah. 00:05:04 Matt Miles says he's never taken a cotton sample that wasn't deficient in calcium, et cetera. Why is it so difficult to get calcium into the plant? 00:05:14 Well, so you need to go, I guess, to 1 0 1 and look how it travels or doesn't travel. Um, not very mobile in the soil travels by mass flow. 00:05:28 If you look at the current drought mon monitor or the NASA version, which is the, uh, grace, uh, shallow underwater index, you'll notice 00:05:42 that there's lots of areas in Nebraska, Kansas, Northern Missouri, Iowa, Northern Illinois that are the ugly shade of brown 00:05:54 and red, which is not very nice. So we're already starting out in large segment of the corn growing areas that are, are 00:06:04 You talking about the corns this color or the soil? Is this color? Whatcha talking about? The drought? Oh, okay. You're 00:06:09 Talking about the drought monitor map. The drought monitor. Well, I, I didn't, I didn't, I've never heard of a gray sheller index. 00:06:15 You're getting a little bit over my head here. That's the NASA version. Okay. There's, there's like the, the Nebraska, 00:06:21 which is the drought monitor, but then there's another one that's the grace, uh, shallow, yeah. 00:06:27 Soil, water, underground, whatever. Sure. Right. A lot of people would just refer to it as a drought mat, but thank you for trying to make me's. 00:06:32 It's one of those Texas, Texas tech things different. I wanna make you feel dumb because you don't know the gray shell drought map. 00:06:37 Drought map. Simplify. Got It. There we go. So we're already starting out in a somewhat of a dry pattern. 00:06:46 Yeah. And last time I checked you start out dry. It's not gonna get any better as we get into summer. It's important, 00:06:52 By the way, if you're, depending on when you're listening to this or watching this, we are recording this on June 2nd. 00:06:57 So by the time you hear this, the weather may be completely different. That still is not going to change the calcium thing, 00:07:02 which we're obvious is our main topic here. But Tom's Tommy's point is when we have drought conditions, what calcium uptake is even more of a challenge. 00:07:09 Is that what I'm gathering? Yep. I, I believe it is. So, so going back to base 1 0 1 facts, if we, 00:07:19 if we know calcium has a hard time moving in the soil, we know that it's already in drought conditions, then we have to use placement as a way 00:07:29 to get it into the plant or tag it along with, uh, different organic acids or other things that aid in plant uptake. 00:07:41 And I think that's what we're gonna get into right now. Alright. So what do we do to get calcium into the plant? You're saying boron and it ride together. 00:07:54 So is it simply a matter of making sure that I've got boron application? We know that, and Kelly 00:07:59 and I covered this at his place, you can throw more calcium out there that doesn't make the uptake. 00:08:05 It's not an issue of avail, it's not an issue of availability. It's an issue of uptake. Right? 00:08:10 Correct. To me, it's an issue of availability. It's not available in the soil. Calcium carries a double positive charge. 00:08:16 He and Tommy's correct. It's not mobile in the soil. The reason it's not mobile in the soil or available in the soil to, from my perspective, 00:08:24 my explanation is that it carries a double positive charge. It's a big, strong, aggressive ion 00:08:31 and it wants to get neutral and it ties up. And so to put it in this, so like, yeah, I can have 90% base saturation. 00:08:39 I can see a hill right over out this window, 90% base saturation calcium, and, but that's, that calcium is attached to the soil colloid. 00:08:47 It's not available to the plant. And I, uh, I can, I always struggle with that. Uh, why? And so every time we go across the field, 00:08:56 we're gonna add some micronutrients, we're gonna add calcium. You know, the, the idea, uh, that I need to split apply 00:09:02 or spoonfeed my nitrogen is a very foreign concept to me. I need to splitly and spoonfeed my micronutrients 00:09:08 because they, they're not available in the soil. The nitrogen is readily available in the soil. For me, Micros make, in my opinion, 00:09:18 'cause I've been doing micros for a long time, micros make the world go around and we talk about them being micronutrients, 00:09:25 but, uh, the vast majority of the time you can see a big influence in a small amount of micro than focusing just on 00:09:35 nitrogen or phosphorus. A hundred percent. Okay. So, so we talk about like, and we're learning this 00:09:42 with Johnny Verell who's doing reduced nitrogen applications, and Kelly, who's going crazy and cutting nitrogen application down to zero pounds 00:09:48 of applied nitrogen, et cetera, et cetera. But I didn't know until working with extreme Ag that only about 35%, one third 00:09:55 of applied nitrogen gets into the plant, which means we're wasting the whole boatload of stuff. Right? Is it that way on the micros too? 00:10:01 I mean, you say they're really important and they're generally under, uh, represented in the sampling. 00:10:05 Is it because we aren't, we, we don't think about 'em and we're not putting them out? Or is it just a matter of they're there 00:10:11 but they're not plant available? They're, they're, they're existing but not plant available. As far as my, my take on it, I don't think 00:10:21 people put out enough. Um, if you look at how people use dry fertilizer and they put in, uh, let's just say 20, 30 pounds 00:10:32 of zinc sulfate, um, is that plant root gonna find that those 20 pellets over a, over an acre? I completely, I completely agree. 00:10:44 The idea that we would use dry micros another foreign concept. To me, the idea that the root's gonna find 'em 00:10:49 and take 'em up, and if it does find them, that they're not tied up to something else. Total waste of money to me putting on dry micros. 00:10:56 So, by the way, that's a really interesting thing because there's somebody that's listening right up until now, and I hope to goodness they stayed on the episode 00:11:02 and didn't like click off and say, ah, yeah, put out more calcium. You know what, throwout dry calcium. 00:11:06 Because the point there is, it's, it's just, it's not, it's impossible. It's kinda like, yeah, a a as you say, 2020 pebbles 00:11:16 of something across an acre, it's, it's 40 feet from the nearest plant. Exactly. So the reason or the plant 00:11:22 Is 40 feet away from the nearest pebble, I guess is the right way to say it. Most everybody, the only reason they're putting out 00:11:27 calcium is to adjust pH. What, which is the total incorrect thing to do as well. I, the total lack 00:11:34 of understanding in the agricultural community, uh, from, I apologize, Tommy from retailers. 00:11:39 Oh, no. P pH is not the problem. Everybody wants to affect the pH as if, if we affect the pH, we're gonna correct everything. 00:11:48 The pH is a symptom of a nutritional imbalance. Correct. The nutritional imbalance 00:11:54 and the pH will fall line, stop trying to correct the pH. Correct the nutritional imbalance. 00:12:01 Interesting. And by the way, there's a whole bunch of people that came up getting their, uh, you know, agronomy from FFA 00:12:06 or v*g class, whatever that were told that, you know, if PHSB, what, 6.6 or whatever, 6.4 to 6.8 or whatever it's supposed to be, and 00:12:14 that'll take care of a whole bunch of stuff. It doesn't. No. Well, well generally if the pH is in that area, 00:12:20 things are going to be nice. But the reason things are nice is because you have nutritional balance. 00:12:24 Balance, All right. It's, You're looking at things from the wrong angle. Alright, So you're about the Tommy Roachs talked about the drought 00:12:32 map, and that makes a lot of sense. We're not gonna go in about the, what, what the drought map is called. 00:12:37 It's called a drought map. And then, uh, and then we just talked about pH does Lyme. In other words, if I have the correct amount of ly, 00:12:46 you're saying that, that people view that as a calcium application when it really it's not Yes. Sort of 00:12:55 Yes. Because if I, like, if I go people here where I live, everybody talks about putting on Lyme and correcting the pH and things like that. 00:13:03 High pH for me is a much bigger problem than low pH. Yes. Now I know it's that thought that way all across the nation. 00:13:09 Okay. And then when people go put on Lyme, you know what? Lyme, they go put on the Lyme that is closest to 'em 00:13:15 because it's the least expensive. Right. You know what the exact wrong Lyme to put on the Lyme, that's the closest to you 00:13:20 because the dysfunction that's in your soil is the same dysfunction that's in that lime. So you're probably potentially making the problem worse. 00:13:27 You're definitely not helping the problem. We did that, by the way, that's one of the best episodes we've ever done is with Kevin Matthews 00:13:33 and he said, your nearest lime source is probably your worst lime source. And we covered that in an episode. It's a good episode. 00:13:37 Uh, is this matter about, okay, you talked about the drought. Does it matter with soil type Tommy Roach? 00:13:41 Does it matter if I've got, if, if I've got Kelly's soil versus Chad soil? Is this calcium thing, is it a different nut 00:13:48 to crack based on soil type? Calcium is calcium and it's hard to deal with, uh, whether it's formulating wise in a, in a NPK fertilizer, 00:13:59 which is what I do, or if it's getting it in the plant, it's, it's a booger and there's different ways to do it. Um, you can, if you look at what calcium 00:14:12 products they're on the market market, and I'm talking liquid, how most people try to trick it up to help plant uptake is 00:14:22 to add amino acids to it, to add organic acids to it, which would be fulvic or something like that. Add sugars, which could be liano, uh, lignano sulfonate 00:14:35 glucco hep inate, or, which is the route we've taken since we're basic in potassium acetate, is we've gone the route of 00:14:47 already having a reacted product called calcium acetate. And we know the benefits of acetate 00:14:53 or many, uh, the basic carbon building block in nature. So we tag that along with calcium to help it, uh, get into the plant better, whether it's soil applied 00:15:06 or folio applied. And if there note, um, we at XT Extreme Ag sat in a hotel suite in Denver and had an entire presentation by Mr. Roach about acetates. 00:15:20 And I never felt so much like the slow kid in the back of the classroom as I did that day. I still, actually, I gotta be honest with you, 00:15:27 I'm still am a little bit lost on the whole acetate thing. I didn't raise my hand because I was like the slow kid 00:15:32 and I didn't want to ask too many questions because then like Temple or somebody I like say, shut up slow kid. 00:15:38 You know, you're getting in the way anyway. You know how that goes around here. Well, was it because you had two beers in both 00:15:42 hands and you couldn't raise your hand? No. Well That was probably part of it too. Anyway. That's why I came, frankly. All right. 00:15:47 I wanna remind you if your farm operation's growing and I hope that it is, um, and, uh, you're getting growth as a farmer, I want you 00:15:54 to think about the challenges that you face and how superior grain equipment's grain storage systems can help you. 00:15:58 Superior grain system, uh, grain equipment's, uh, grain storage systems are built to make your job easier and help your grain reach its full potential from things 00:16:06 like their gentle mix flow dryers to the durable storage. You can get the flexibility 00:16:09 to market your grain on your time. You can visit with the experts at Superior Grain at this year's Farm Progress show in Decatur, Illinois. 00:16:16 Or you can visit them online anytime@superiorbins.com. That's superior bins.com. Um, what about then the regionality of it? 00:16:24 Climatological, you said calcium's calcium, you said soil doesn't matter. What about temperatures? Is it, is it a harder fight 00:16:30 for Matt down in little Vietnam than it is for Lee up in South Dakota? Or is it temperature not matter? 00:16:35 Well, anytime you have hotter temperatures, plant tends to shut down and doesn't wanna take up anything. So Matt has a much shorter window, uh, to hit that 00:16:46 during the day than say Lee does in South Dakota. Got it. Or even Salmon Canada. Yeah. And crops are different. 00:16:56 I mean, cotton plant needs, uh, a lot more calcium to fill out that bowl and fiber than, um, 00:17:07 and I'm not saying that it's not needed, but soybean doesn't take a lot of calcium at all. I mean, if you look at, if you look at all the nutrients, 00:17:17 calcium is the least that, uh, that is needed by a soybean plant. So What needs it the most? You said 00:17:24 cotton Cotton needs it the most Out of traditional world. Crops. Crops. Um, I would say cotton does. Yes. 00:17:31 And corn. Yep. Got it. Um, alright. We said we're talking about balance. And this has been Kelly's big thing. 00:17:39 Three years ago, Kelly's big thing was stress mitigation. Then he is moved into, uh, 00:17:43 crop balance was a big thing a couple of years ago. Now he's moved into more about nutrient analysis of the, of the crops he grows. 00:17:49 But your thing was balanced just a couple years ago and you mentioned it already today. And then Kel uh, well, Tommy said something about boron. 00:17:57 Um, what, what is it that I need to be thinking if I'm listening to the show about balance? How, where am I probably imbalanced If I'm a normal American 00:18:05 farmer, where am I? Probably Im balance that's harming me on calcium uptake. Um, I would say 00:18:15 that you probably have more nitrogen than you need and you're lacking all nutrients, including calcium. But calcium is, as Tommy said before, a booger to work with. 00:18:24 And I think a lot of times it gets left out or skipped over in a foliar plan because of the difficulty of working with it. 00:18:32 And there just aren't very many products that you can mix with other micros. 00:18:37 I think all of them, again, uh, the general farmer, I believe across the Midwest has, is out of balance. They're heavy nitrogen and the deficient micros, 00:18:47 but the micros they do address are not calcium isn't among them because of the difficulty in working with it. And so you need to find a product that you can mix, 00:18:57 because we're not gonna add a pass. No farmer's gonna go out and put on their zinc and bore on and maum and then, and then come back 00:19:03 and make another pass with calcium. They're not gonna do that. And that's the reason that it, that's the reason that it is the oftentimes 00:19:10 the most left out one. He's the only guy in that entire Garrett land and cattle farm office who can say the word molybdenum. 00:19:17 His agronomist, who is a very intelligent guy with calibrated agronomy. My friend Mike Evans just keeps saying Molly, 00:19:23 and then finally said, what, what's that short for? He can't say molybdenum. Why is it so hard? Tommy, He's from Iowa. 00:19:36 What's the deal on balance that, from your perspective, that I wanna talk about the how-to guide on how I actually get more calcium in plants. 00:19:42 What's, what's the imbalance issue that causes the, the, the, the calcium to be so difficult to work with? 00:19:49 Me or Tommy? Tommy Roach said the boron thing. Well, let's take, let's take Kelly's example. I mean his, his two most limiting nutrients, 00:19:56 calcium and zinc. How, how many people? We've already talked about how many people apply calcium, which I would, 00:20:04 I would probably say no. Almost zero. I think Kelly's the only one almost zero in a, in a corn soybean rotation. 00:20:12 Uh, I just, I just don't think they pay enough attention to anything other than nitrogen. 00:20:18 Yeah. Phosphorus, sulfur. I mean, they don't even pay attention to potassium. They, the ones that do deal with it the wrong way, 00:20:25 they throw out dry pot ash and think that's solving a problem. All right. Uh, how to guide part of it. 00:20:32 How do you get calcium into your crops? We did a short video about this in the field behind your, uh, shop Kelly. 00:20:39 Um, if I remember, is that the one where we, we used, you did an experiment with your subsurface drip irrigation. I, I think, am I right about that? 00:20:48 Yeah, well, we, uh, we've tried to put it into the subsurface drip. We, it's the, the only fertility that is left on my planter, 00:20:55 uh, in the inferral mix is calcium and zinc. Uh, and then when we're going across the field in a foliar application, you know, the post chem, we'll have, uh, 00:21:05 calcium in it amongst the other micros. And then when we get to the R stages, you know, and we're taking the rapid soil test 00:21:11 and the SAP test, uh, I can't guarantee that calcium would be in there, but I bet you it will be because it's always one that we need 00:21:18 to spoonfeed, uh, consistently. So we, we are, it's planner applied and then fully applied with the sprayer 00:21:25 and then the airplane, I might put calcium on potentially five times throughout the year. 00:21:30 Planter, planter, the sprayer, and the post cam. And there's the potential to fly the plane three times. And when you're flying a plane three times, 00:21:37 which is getting expensive, that's a fungicide pass. And what else? Uh, so let, let's address that. 00:21:44 I don't wanna call it a fungicide pass Because you, you're trying to back off of fungicides anyhow. 00:21:48 If I, if I balance my crop, yeah. I'm not, I'm not saying fungicides are bad. I'm saying fungicides are defense. 00:21:54 And if, if I do a good job and get balanced in the plant, I don't believe that I'll need the fungicide because the 00:22:00 plant will be healthy enough. It'll have natural immunity. So if we balance the plant, 00:22:05 so then you wanna talk about the expense fungicide is $30 an acre. I've turned my nitrogen down, uh, 40%. 00:22:13 I've turned, you know, I've, uh, um, I continue to turn down the nutrients. I will tell you that I, I'm raising corn cheaper. 00:22:21 Uh, last year we had those challenge plots at Matt Miles because it was said that I could do, I could do 00:22:26 what I do here in Iowa 'cause of the soil, but I can't do it anywhere else. So we raised, uh, 00:22:30 challenge plots at Matt's for his field day. Matt raised 240 bushel corn. I raised 240 bushel corn. I did it $50 cheaper. Cheaper. 00:22:39 Don't tell me it's more expensive. You're nodding your head, Tommy. It's the people that are driving a tractor right now. 00:22:44 They can't listen to you. Nod. Why are you nodding? You just like the idea that did something better than Matt is that it, 00:22:50 It goes back to people pay too much attention to nitrogen, they put out too much, uh, 00:22:56 which throws everything out of balance. So tell, well, uh, Kelly just said I put it on as much as five times. 00:23:04 Somebody's listening to saying, oh, I don't even go over my field that many times. Well, if you don't have a sophisticated planter, 00:23:10 can you still put calcium on that time of planting? I'm assuming you can. You can. If you could use, you could use, there's 00:23:18 Different, it be two by two or in furrow technology to do that. There's different, there's different products you can use. 00:23:23 I mean, if you're gonna, if a lot of people run phosphorus in a, in a infer or two by two, the, if you are trying to 00:23:33 mix calcium in with phosphorus, it has got to be a hundred percent chelate, which limits it to a calcium A DTA. 00:23:42 Now if you're not using phosphorus, like Kelly's not, uh, that leaves your options a little bit wider. You could use, um, products that are 00:23:55 may maybe amino acid based or acetate based because calcium acetate and phosphorus don't even, don't even think about it. 00:24:05 'cause they will make calcium phosphate, which is goes back to natural state. You know what you want. So, but they're, they're not, 00:24:12 they're not antagonistic. They just freeze each other up. Tag each other up. Yeah, Exactly. They want 00:24:16 to go back to how they were in nature. Calcium phosphate. Alright, so the person that says, I wanna be 00:24:22 to put on more calcium because I just heard it from Kelly that I can put it on, I can figure out a way 00:24:26 to do it even if I don't have in furrow or two by two. How do I do it that way? Planter box, seed treatment. I don't know. What are we talking about? 00:24:32 Well, you can fully your apply it. I mean if you look at nutrient uptake and in corn, the vast majority of calcium is needed. 00:24:40 And that we'll just say VV 12 to R two. I mean it's directly tied to starch accumulation, nitrate uptake. 00:24:52 Mm. I mean at that, at that V 12, you're putting on a lot of cells and you've got to have calcium of boron 00:24:59 for cell stability. One of those things that's getting flown on Kelly is what it's, it's what's in it, what's in the stuff 00:25:05 that goes on at, you're talking July, August, August probably. What are you putting on? Oh, like last year on July 12th there was copper, uh, 00:25:15 copper, manganese, iron, boron, calcium, zinc, you know, and then there's uh, some biological products, things like that. 00:25:23 It, uh, it depends on what the SAP test tells us is needed and then in what amounts. 00:25:27 Okay. And then the person that says, I don't know if I can justify the expense to fly something on, uh, 00:25:32 late in the season like that, you're gonna tell 'em We are reallocating that fungicide spend. We're reallocating some pesticide spend. 00:25:40 We are reallocating some nitrogen spend. Uh, we've taken all fertility off the planter. There are many people that put 00:25:47 phosphorus on with the planter. We were one of them throughout extensive trials. We took all of that f fertility off the planter 00:25:53 and reallocated it to later in the season. If you would like to know my opinion on what in my soil, what phosphorus on the planter produces it's vegetation. 00:26:01 It's not yield, it produces vegetation. What I put on with the airplane later in the season produces yield re I'm not telling you should spend more money. 00:26:09 I just showed you where I spent $50 an acre less. Yep. Reallocate that spend to later in the season. You have to educate yourself on 00:26:18 what your soil's producing, things like that. Uh, just yesterday there was a coffee shop conversation and they said, well, we think you're crazy 00:26:25 that you turned your nitrogen down that far. It takes 1.1 pounds of nitrogen to produce a bush of corn. And I'm like, I never said it didn't. 00:26:32 Well, why do you think you need to put it all out there? Your soil's providing some of it for free. 00:26:36 Why don't you take advantage of that and then reallocate that savings to that airplane pass. Yeah, I like it. 00:26:43 How do you manage what you don't measure? Nobody's measuring what the soil's providing. Nobody's measuring what the plant needs. 00:26:50 How do you manage what you don't measure? And then they want to tell me that the SAP test is too expensive. 00:26:54 You might spend $30 an acre on a foliar app and I could go, I could go run one SAP test for $110 or whatever. 00:27:01 It's that an 80 acre field time serves $2,400 you're gonna spend in the application on this field. 00:27:06 And you think it's too expensive to take $110 test to validate what we need to put out there. Tommy, I'm kind of surprised he even even 00:27:13 stopped in the coffee shop. I, I, I mean, why, why go there to get judged But turn's chest? 00:27:20 Uh, all right. Um, I I, I had one of my things in my question. How do you know it's working? Well, you did 00:27:25 the tissue sample test. Um, again, the person that says I need to put more calcium in you, you did it through testing. 00:27:31 Do you think that most people would just do well to figure out a way to get a foliar pass on calcium even if they didn't do the testing? 00:27:36 'cause you can just almost blank it. Tell 'em, I'm just going to 90% chance you're deficient. Yes, I do think that they would be doing well to just try 00:27:46 and see what the yield is at the end. But in the tight margin environment that we're in and things like that, I, I always wanna measure it to see, 00:27:54 you know, like last year though, that the July 12th application that I referenced, we put on 20 ounces of a 6% copper 00:28:02 and we moved the sample, the SAP sample, we moved the copper like 2000%. We probably don't need to do that. 00:28:09 We probably could dial that back to 10 ounces of copper. You know what I mean? Something like that. 00:28:12 So we use that SAP test, actually calibrate the pot product. We, we moved the, uh, potassium up 00:28:19 and this was at like vt, give or take. Okay? So we are super excited that we actually moved the potassium up 1.4%. 00:28:27 I would rather, you know, and the co that copper spend isn't a lot of money, but when we get down to the really, the nuts 00:28:33 and bolts of it, what if we have the expense on the copper and add a little bit more to potassium to try 00:28:38 to even raise that a little bit more? And so I always believe that the SAP test is worth it to really dial in on what we're doing. 00:28:47 Mistakes is my last thought here, by the way. You want any, anything to conclude that Tommy? I don't. Well, no. 00:28:53 And all these, this discussion about other nutrients, it all fits in with, with this calcium topic. 'cause I don't think people understand that calcium 00:29:07 activates a, uh, proton protein pump that pumps all these nutrients into the plant. That being phosphorus, nitrogen, potassium, 00:29:21 magnesium, boron. You go right down the list and without available potassium, guess what? You limit your limit, your nutrient uptake 00:29:30 of all these other nutrients that we've been sitting here talking about. You said without available 00:29:34 potassium or you mean available calcium? Available Calcium. Yeah, There we go. That's the top, that's 00:29:38 the topic is calcium. I know mistakes that, uh, someone is trying to get more calcium plants, 00:29:44 they understand they got this problem and then the one thing that they're like, oh crap, I wish that I'd have known because have you ever made a mistake, 00:29:51 Kelly, that, so that in your attempt, in your effort to get calcium into your plants, have you spent some money that didn't end up giving you a return? 00:30:02 Yes. If you don't apply, you know what in soybeans when we didn't apply at the right time, you know, we, because we're trying to save that pass, 00:30:08 things like that, you know, in corn, uh, like the, the calcium that we were using was about eight bucks an acre. 00:30:14 Uh, this was a couple years ago. We had a 10 bushel yield gaining corn. Uh, and that was in a 300 bushel yield environment. 00:30:21 So a 10 bushel move in a 300 bushel environment is a big move that was on irrigated acres. 00:30:26 Okay. Um, in beans we had a three bushel, uh, move. So in B $8 beans is a pretty pedestrian price and I always want to have a three to one return 00:30:38 and we had a three do three bushel return there. And then, but then like the cells that Tommy talks about, you know, the cellular strength in very high yielding beans, 00:30:47 if we don't have the cellular strength, the the, they have a hard time supporting themselves. Yep. And, uh, so the calcium in an indirect way can lead 00:30:55 to an even bigger yield gain there just, just by, uh, supporting the plant better. Most of the calcium that a soybean needs is in the stems 00:31:04 and stems and leaves. It's not in the, the actual bean itself. So It does need to be applied for vegetative 00:31:10 because one of Kelly's big points is you can do a whole bunch of stuff that creates vegetation, but it doesn't create yield. 00:31:14 Like that's why he said he's taken stuff off of the planter creating a bunch of vegetation. Uh, you're just spending money at the wrong time. 00:31:21 And we were, when we're talking beans, I mean, it, it is, i i I would love to deal almost 100% with 00:31:30 in season fertility because you can, you can greatly enhance your beam production just by doing everything say our stage forward. 00:31:45 Got it. All right. So if you wanna learn more about this, go and check out a couple of videos. 00:31:49 These guys did one and then also Kelly and I have done one. And then I know Matt has talked about calcium. 00:31:54 So we've covered calcium quite a bit, but we're covering it quite a bit because it's that important to your farming operation. 00:31:59 If you wanna take your farming operation to the next level, make sure you come to one of our field days. 00:32:03 We are recording this early June. I don't know when you're gonna listen to it, but maybe you're gonna hear this in time to go to 00:32:07 Matt Miles, which is on June 12th. June 26th. We're gonna be in northwest Iowa at Kelly Garrett's farm. 00:32:12 Great time, always there. Um, you can go to the Extreme Mag Farm website and sign up for any of our field days. 00:32:17 They're free to attend and we would love to have you there, but you do have to register in August. 00:32:22 We're gonna be at Verres on August 5th, that's in Jackson, Tennessee. On August 7th, we're gonna be in 00:32:26 North Carolina at Kevin Matthews. August 20, uh, I'm sorry, August, uh, 15th. We're going to go across the border. That's right. 00:32:33 We're gonna go up there to what might be our 51st state. We're gonna go up there and we're gonna check out 00:32:38 our friend at Sam CHUs. It's not really gonna be our 51st date. Uh, we're gonna go to Quebec for the first time ever 00:32:43 with extreme ag for the field day at Sam CHUs. And then on August 21st we wrap things up at our friend temples in, uh, in, in Maryland. 00:32:50 So go to the Extreme ag.farm. If you, while you're at the Extreme ag.farm website, make sure you check out our show. 00:32:54 The Grainery, our very first sponsored shows we're sponsored by none other than our friend Tommy with Nature's. 00:33:00 And it's a really cool show. Pull up a chair, it's real farm talk with real people about real issues from 00:33:05 the personal to the professional. If you wanna learn more about Mr. Tommy Roach and their lineup of products 00:33:09 that can help you farm better, where do they go? natures.com. Nature's dot com. N-A-C-U-H-N-A-C-H-U-R-S natures.com. 00:33:18 So next time, that's Kelly Garrett, that's Tommy Roach. We're talking about how to get more calcium into your plants. 00:33:22 I heard a lot of it there. Do stuff at time of planning multiple. You can't put it out all at once. 00:33:26 Five different applications from Kelly Garrett, small doses, and all of a sudden keeps your plants not deficient. 00:33:31 Is that what I heard? Is what I heard. Right, Kelly? You heard 90 plus percent chance you are deficient in calcium. 00:33:38 Pull some samples to see if maybe we're right and we probably are. And we can help you farm better. So next time. 00:33:43 Thanks for being here. I'm Damien Mason with extreme Ag cutting the curve.
