Franklin Family Farm
Tim Franklin, Goodland, KS
Tim Franklin operates a midsize farm with his wife and his parents in northwestern Kansas, near Goodland. About a quarter of their acres are irrigated, the other ~75% is in dryland crop production. They mostly grow corn on their irrigated land, sometimes rotating with wheat.
Motivation. When my wife and I moved back to the farm in 2011, my dad tasked us with figuring out how to transition the irrigated part of our operation over to dryland production. Our family was concerned about well decline and the possibility of different state level controls coming in (such as an IGUCA or other measure being put into effect by groundwater management districts a.k.a. GMDS) that might reduce allocations or cut off wells with lower priority permits.
Initially, when our family first started really talking about water, we were thinking along the lines of “leave us alone, we’re doing what we can and we are conserving in our own way; we’re doing what’s best for our own ground.” We were already doing some things to improve water conservation on our farm. We’d knocked off lower hanging fruit, setting up LEPA systems on all of our sprinklers, with drops 3-5 feet off the ground, for example. Going to some GMD meetings, though, we were struck when we heard someone say “let’s stop kicking the can down the road, we need to do something now” to meaningfully address aquifer declines in our area. That’s when we started looking seriously at Kansas’s Water Conservation Area (WCA) model, which my parents had heard about from the Farm Bureau and newspapers.
We had several conversations with the Farm Bureau and staff with the Kansas Department of Agriculture (KDA) to learn what options and requirements we’d have with a WCA, and also to make sure we wouldn’t be hurting ourselves by setting one up. We lobbed several proposals back and forth, all the while talking on our end about the potential upsides and downsides: was a WCA doable and did we think it would it help us, or not?
During one conversation with KDA, my dad said, “it’s hard to be against the conservation of water. When my kids and grandkids look back, I want them to know that we did what we could to save water for their generation.” We decided to give the WCA a try for a year. We said to ourselves that if the rubber hits the road and it didn’t work that we could write a letter to the State to dissolve it.
We like the flexibility of our WCA, which lets us roll a portion of our annual allocation forward. Water we don’t need—such as when we got hailed several times this year, or during a wet year like 2017—gets saved for another dry year that we know is going to come, like 2012, when we’ll need those acre-inches of water to be successful growing some kind of crop. In the first two years of our WCA we’ve been able to “bank” a year’s worth of water.
Management methods. We don’t have the biggest well capacities on our farm, and it’s possible our neighbors would say this is why we set up a Water Conservation Area. We’d say, though, that for us the WCA is actually more about our farm management. For example, we try to have our water turned off by the first of September to let winter precipitation recharge the soil profile, while some of our neighbors keep their pivots on to pre-water.
In the past few years (or since implementing the WCA?) we’ve switched from strip till to no-till management to save water on our irrigated land. No-till poses some challenges in and of itself, especially with managing residue, in trying to raise profitable corn. We’ve made some equipment modifications on our planter to deal with crop residue and get better seed-soil contact for better stands. Compared to strip till, no-till management has some contingencies. With strip-till I could get out to the field whenever I wanted, day or night, and I could drive a bit slower. With no-till, the sun has to be out and the residue has to be dry or I become a big rake dragging residue around.
We’d dabbled with using soil probes in the past but didn’t have as much success with them until we started working with consultant Cory Gilbert and his team from OnTarget Ag Solutions; they seem to understand our soils. We now have a probe in every irrigated field. Cory used Varus soil mapping to identify a spot representative of the average soil moisture holding capacity in each field so that we can extrapolate from there how the rest of the field is doing for moisture.
You hear a lot of talk about whether soil probes are accurate or not, and how important that accuracy is for them to be valuable. Our farm definitely finds using soil probe data to be valuable. While the probes won’t tell me if there’s 1.25 inches of water that my plant can take up in the top 18 inches of soil, I can tell using them what depth water is getting to, whether from it’s from rainfall or irrigation. If I’m fertigating, using soil probes lets me know how much to run my pivot to keep the water within the top 10 to 24 inches of soil. They also give me an idea of how active plant roots are at different levels, which helps in more ways than one, in part because root structures of different varieties of corn can vary so much.
Having a soil probe in each of our irrigated circles has definitely saved us money. How we manage water on our farm using the probes and residue helps keeps nutrients in the root zone, preventing money we’ve spent on them from leaching or washing away. On average with dry and wet years, if you made me guess, the return on investment time for soil probes is three to five years. In a wet year, soil probes probably pay themselves with the money they save each time you decide you don’t need to go around with your pivots.
[lay this paragraph out as a box separate from the main text] Over time, I expect that soil moisture probe technology will only improve. I don’t have an agronomy degree, and I can’t tell you every kind of soil I have in my fields, but the soil probe is a tool that helps me manage my water more effectively for sure than I was doing before. Are they perfect? No, but the information they provide is a lot better than what we had before (less/no information). If we get an inch of rain, I feel much more comfortable and confident about how long I can leave pivots off. Before I’d be heading out with a shovel several times each growing season to soil sample and make decisions.
Mistakes. Once, in an earlier attempt to use soil probes, working with a different company than we do now, we had a probe that wasn’t working. The company we were working with hadn’t GPS-located any of the probes they’d put out. We didn’t want to hit it with the combine, and my wife and I ended up walking through the field to try to find it. I didn’t even think about that when I was checking it early in the season, but it’s another thing altogether to try and find a probe in eight foot tall corn. I was kicking myself because it would have been a simple fix just to go out there with my phone and drop a pin to mark where the probe was.
Money Matters. Our approach in planting low seed populations (provide a range) ultimately it comes down to profitability. We raise 300 bushel/ac corn, but have found that’s less profitable for us than if we aim for somewhere around 220 bushels/acre.
Seed companies don’t seem to do much low population testing of their varieties. Being able to trust and rely on local dealers who have good idea of what different varieties can do and how they will respond to stress is important. Our discussions with OnTarget on potential yield led us to change varieties, positively impacting our profitability; that’s what we pay them to do. [We could cut this paragraph]
[lay this paragraph out as a pop-up box?] At the coffee shop or talking with input suppliers you can get sold on the idea that “if I use this one product, it will add X bushels more of corn, this other product will give me another 5 bushels/acre,” and so on. The next thing you know, based on what you’ve invested with inputs you should theoretically be growing 300 bushel/acre corn, but this kind of thinking can kind of cover up what you’ve spent to grow whatever crop yields you actually get (probably less than 300 bushels/acre). It’s just not always worth it to spend more.
This coming year we will be variable rate (VR) seeding every acre of irrigated corn and VR applying nitrogen and phosphorus on those fields. Because of VR we are dropping fewer seeds, which lowers crop water requirements. Since hybrids react differently under stress, I rely on OnTarget’s knowledge of corn varieties that, planted in our soils at lower densities, will be able to hit our yield goals. With our well capacity, if we get a dry year we can’t keep up with plant water demand: you could say we play defense in how we farm by intentionally planting low-density populations of corn so that our crop can survive a little longer with the water we have if we get end up with a drought year.
Recently we’ve also gotten into using VR strategies on our dryland acres. Savings gained with VR on our irrigated acres paid write the VR scripts for our dryland acres. With variable rate, we can optimize seed populations for areas with greater or lower soil water holding capacity. We gain some savings by not planting a flat rate as well as with VR fertigation of nutrients. Our goal on both our irrigated and dryland acres is to be efficient as possible and hit our yield targets, rather than shooting for high yields.
This year (2018) we got hailed badly several times. Rather than trying to raise 220 bushels/acre corn, we cut our water use back to meet the needs of the plants still out there, aiming for 50-60 bushels/acre yields instead of 220 bushels/acre. At the end of the season, had our crop insurance adjuster challenged us on the yields we posted, our soil moisture probe data protects us because it shows that we provided sufficient water to the crop that remained after the losses incurred through hail damage.
Mindset. Some people farm going by their gut, keeping track of what they spend and earn in their head. Our approach is different: we focus on maximizing profits by keeping track of and adjusting our seeding, watering and nutrients at the sub-field level to reach target yield goals. A seed dealer I was visiting with recently told me I was one of only three farmers he’d spoken with so far who is trying to do that.
Getting into using precision agriculture strategies to improve profitability doesn’t have to be a costly investment. A cheap hydraulic pump (is this on a planter, for fertigation or both?) that runs using the GPS on your tractor costs $4,000-5,000. Equipment these days comes with advanced technology options that people may not be using- yield monitors, for example (Tim, is that accurate- I didn’t capture what example you provided in my notes.)
With our WCA and shifts in how we manage, our farm’s water future looks more positive than it did before. The possibility of drying up our irrigated acres is still in the back of our minds, which partly drives why we’re figuring out VR strategies for our dryland acres. This year turned out to be an average moisture year; we know we can raise pretty good no-till dryland corn with advancements of VR scripts and how the corn varieties flex. Meanwhile, discussions on water in our area, partly from WCAs and our groundwater management district’s new district-wide Local Enhanced Management Area [insert link] is making us and our neighbors more aware than before of what we can do to conserve water. That’s a positive thing.
