Reevaluating Fertility without Compromising Yield
Kelly Garrett discuses the crucial balance between necessary cuts and maintaining soil health for optimal yield amid potentially sub-$4 corn prices.
Garrett shares his approach of focusing on leveraging "savings accounts" in soil fertility and prioritizing foliar and planter fertility, especially vital nutrients like phosphorus in the early stages, to better support plant development during critical reproductive phases.
00:00 Hi, this is Kelly Garrett from Extreme Ag. I'm here with Aaron Stahl at 2024 Commodity Classic in the Agro Liquid Boost. 00:06 Aaron, we've got $4 corn, potentially sub $4. Corn growers are talking about changing their fertility programs. 00:14 I know I have my thoughts on it, but I'm interested to hear what you have to say. So for us, you know, Kelly, I look at, I like 00:20 to look at a soil test and figure out what's, what's the ROI, what are they looking for, you know, and I, the farm shows I've been at, 00:26 the big thing is is I'm gonna cut out my plantar nutrients. I'm just gonna go with what I have. 00:31 And for me, I'm like, you know, we need to reevaluate some of this stuff. You know, what are your phosphorus levels, zinc, 00:36 phosphorus levels, things like that. So I may pull it back a little bit, but I don't believe in totally cutting it outta the program 00:42 because let's face it, $4 corn, we're not gonna, we're not gonna get ROI at 180. We need 200, 2 10, 2 20, 2 30 on up. 00:51 So what are you thinking? I mean, what's, what's your thoughts on pushing that? My opinion over what I have experienced 00:58 and educated myself the last couple years, but if you have a good soil test, live off of that savings account for a year 01:03 or two in a tough economic time like we've got right now. And the thing to cut out is not our liquid fertility, 01:10 it's the dry fertility because of that savings account, we have built that soil up. We've got a good base saturation number, 01:17 we've got good phosphorus levels, good potassium levels. We're not gonna deplete those in one year. Yep. 01:22 So instead of, instead of cutting off our plantar fertility or our foliar fertility, let's cut out that, 01:27 and I'll take it one step further. There's nine things in my inferral corn mix. There's eight things in my inferral soybean mix. 01:34 They're the same except for insecticide, liberate calcium is in my inferral and zinc. Those are the only two fertility things on my inferral. 01:43 I don't wanna take those out because they're tried and true products that return an ROI, a lot of the fertility that I had on the planter in years past, we've now moved 01:51 that to the R stages in the airplane. American agriculture does a great job of producing a sexy vegetative crop. 01:57 Yep. I wanna produce a reproductive crop. And fertility in the R stages is paramount to that. Yep. We need to fertilize in the R stages with the plane. 02:07 I'm now flying the plane at V 10, R one and R five and I see a yield gain and an ROI from that every year because that's when the plant is hungry. 02:16 That's when the ear is filling. And farmers a lot of times will worry about getting enough pounds of stuff on. Well, when we have a good soil, a good balanced soil 02:24 with available nutrients, and then we apply with the plane or, or the drone or the, or the haggy, whatever it may be. 02:31 In those R stages, there's an ROI, again, with $4 corn, that's what it's all about. It's about an ROI And also, 02:40 when we're talking about 8% interest, uh, seven, 9% interest, whatever it may be, when you don't have to spend those dollars for a few months. 02:48 Yep. Think about that savings. Correct. You know, uh, my, my grain bins right now are empty of corn. You know why? The biggest return I could get 02:55 is that 8% interest. I was gonna ask you that. Well, let's look at that from a perspective of our fertility 03:00 and now, so we don't have to spend those dollars right away. And then what, what if there is a windstorm? 03:06 You know, God forbid, what if there's a windstorm? What if there's a hail event? Uh, what if there's a terrible drought? We don't know. 03:12 But you don't have to make that decision kick that can down the road. Correct. But I would not cut out my liquid fertility. 03:19 I don't, I in my soil, you know, different geographies around the nation. In my soil though, putting a big load on 03:25 with the planter doesn't pay, putting a big load on with, you know, quote unquote big load with the plane does play. 03:31 And when I say big load, it's still only a couple gallons. Right. But it doesn't take much when 03:35 we're treating the plant. So have a balanced soil, treat that plant later. And I, I think that's when special things happen. 03:42 And for you, you know, when we met and we talked about your plant food and stuff, you got a heavy load of phosphorus there. 03:47 Now you're talking about putting in some of our proger in there. So Yep. That's What I'm trying to get guys to understand that 03:52 what they're putting up top is not necessarily gonna get to the plant. And let's start looking at getting 03:56 that corn off to an early start. So what are, what are your thoughts? What are you doing? I, that is something new 04:01 that I'm glad you brought that up. That is something new that we're gonna do. We're gonna put pro germ, 04:04 we're gonna put phosphorus back on the planter this year, especially on the early planting. 04:09 I'm gonna be about 80% corn. We have over 5,000 acres of corn to plant this year. Uh, our weather guy that we, you know, we subscribed 04:16 to his forecast, he's talking about a potential frost on Mother's Day for me, May 14th. 04:21 So that early corn needs to have some phosphorus to help get up and get going and quote unquote early corn. Might be a lot of it this year if 04:29 there's a frost on Mother's Day. Yep. Because, you know, what do we mean by early corn? We mean cold conditions? 04:33 Well, if it's still cold on Mother's Day, a lot of it's gonna be put in the cold weather. So that pro germ we believe is a missing piece. 04:40 I also believe we'll be adding phosphorus with the plane. We've been spraying micronutrients 04:44 and potassium with the plane for a couple years now. Now we need to add phosphorus. I don't believe that in the late season. 04:50 I don't believe the root system of the plant brings up everything that we need to help the plant reach potential. 04:56 I think phosphorus is the last piece there as well. That's be something that we're adding this year. So I really think farmers should look at what they need 05:04 to cut out that dry fertility that we've been used to for all of our farming careers and even generations. That is the part that you can cut out 05:12 because of the savings account. It isn't that it's not important, but you've probably built your soil up where it's okay. 05:18 And just don't believe for a second that you're gonna deplete that it's okay to cut that out for a year and stay with the products 05:24 that we know are gonna give us an ROI, let's let's be mindful and have a, a total perspective of what we want to cut. 05:30 Right. And I think that'll lead to a more successful year.
