Latest / The 5G Podcast with Fexingo: Wireless Networks, Carriers, and Mobile Infrastructure / How 5G Is Quietly Transforming the Agriculture Industry
Transcript
- Lucas: If you think about the industries that are least associated with cutting-edge wireless tech, agriculture has to be near the top of that list. But there's a quiet revolution happening in farm country, and it's being powered by 5G. Luna: I've heard about precision agriculture, but I always assumed it ran on Wi-Fi or maybe satellite. What's 5G bringing that's different? Lucas: Right, so the big change is real-time connectivity at scale. Historically, a tractor might collect data as it plows — soil moisture, nutrient levels — but that data gets uploaded at the end of the day over Wi-Fi. With 5G, the tractor can stream that data live to the cloud, process it with AI, and send back instructions within seconds. We're talking about variable-rate seeding: the tractor adjusts how many seeds it plants per square meter based on soil conditions detected in real time. Luna: So the machine is making decisions on the fly. That's a huge leap from the old 'set it and forget it' model. Lucas: Exactly. And the company leading this is John Deere. They've been embedding 5G modems into their newest tractors — the 2025 and 2026 model year 8R series, specifically — and they've partnered with Verizon and T-Mobile to get coverage onto farmland. Deere is also building edge computing units directly onto the tractor, so even if the 5G signal drops, the local AI can keep running decisions for a few seconds. Luna: That's smart — because rural coverage is still spotty. I remember reading that about 20 percent of US farmland doesn't have reliable cellular data. Lucas: Yeah, that's the bottleneck. But here's where it gets interesting: Deere is exploring using the tractor itself as a mobile small cell. So the tractor acts as a 5G node, relaying signal to other equipment in the field. You could have a combine harvester two miles away connecting through the tractor's antenna. Luna: That's essentially turning farm equipment into a mesh network. How far along is that? Lucas: It's still pilot-stage. A few large farms in Iowa and Nebraska are testing it this planting season — spring 2026. But the early results are promising: they're seeing about a 12 to 15 percent increase in yield on fields using real-time variable-rate seeding compared to conventional methods. Plus, water usage dropped by roughly 20 percent because irrigation can be targeted exactly where needed. Luna: Those are real numbers. So this isn't just a tech demo — it's actually moving the bottom line for farmers. Lucas: Absolutely. And the cost is coming down. A 5G modem module for a tractor adds about $1,500 to the price tag. For a farmer spending half a million on a new combine, that's a rounding error. The ROI shows up in the first season. Luna: So what are the implications beyond just tractors? I imagine this ripples through the entire supply chain. Lucas: It does. Grain elevators, for example, can use 5G-connected sensors to monitor moisture and temperature in storage silos in real time. That reduces spoilage, which the USDA estimates costs US farmers about $3 billion annually. And when the crop is ready for transport, 5G can coordinate autonomous trucks and drones to move grain from the field to the elevator without a human driver. Luna: Drones are already used for crop spraying and imaging. How does 5G improve that? Lucas: Today, most ag drones fly pre-programmed routes and store data onboard. With 5G, they can stream high-resolution video and sensor data to a central AI that identifies pests or disease in real time. The drone can then adjust its spray pattern immediately — only targeting the infected plants. That reduces pesticide use by as much as 90 percent in some trials. Luna: Ninety percent — that's staggering. And it has obvious environmental benefits. Lucas: Right. And it's not just about saving money on chemicals; it's about meeting regulatory pressure. The EU, for instance, has mandated a 50 percent reduction in pesticide use by 2030. 5G-enabled precision spraying is one of the few tools that can make that target realistic. Luna: So the regulatory tailwind is pushing adoption as much as the tech itself. Lucas: Exactly. And I think that's why the investment is accelerating. In the first quarter of 2026, venture capital in ag-tech hit $2.2 billion globally — that's up 35 percent year-over-year. A lot of that is going into 5G-connected sensors, autonomous equipment, and edge computing. Luna: Do you see any downsides? I mean, what happens when a big farm's 5G network goes down during planting? Lucas: That's a real concern. Deere is designing for graceful degradation — the tractor can fall back to onboard stored maps and pre-set seeding rates. But you lose the optimization. So there's a push to have redundant connectivity: maybe two carriers' SIMs in the tractor, plus satellite backup for critical commands. It's not solved yet. Luna: Speaking of what keeps this show running — and maybe this is a stretch, but how do you think listener support actually helps cover topics like this? Because it's not the most obvious headline-grabbing story. Lucas: It's a fair connection. This show doesn't run ads, and that's intentional — we want to go deep on stuff like 5G in agriculture without a sponsor shaping the angle. The support we get from listeners, through small contributions, is what makes that possible. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it's a small thing that adds up. And it lets us spend time on stories that might not get covered elsewhere. Lucas: Exactly. So — back to the tech. Another frontier is livestock. 5G-enabled collars and ear tags can monitor cattle health in real time — heart rate, temperature, even rumination patterns. If a cow shows early signs of illness, the rancher gets an alert on their phone. Luna: That's a lot more precise than a rancher driving out to check the herd twice a day. And it probably saves on veterinary costs. Lucas: For sure. One Texas ranch with 10,000 head reported a 30 percent reduction in mortality after deploying 5G-connected health monitors. The collar costs about $50 per animal, but the payoff is clear. Luna: So connectivity is essentially becoming a new input — like seed or fertilizer. You can't optimize what you can't measure. Lucas: That's exactly the frame. And that's why I think 5G in agriculture will see faster adoption than in many other industries. The ROI is direct and measurable. You don't have to convince a farmer that connectivity is valuable; you just show them the yield data from the field next door. Luna: What about small farms? A lot of this tech seems geared toward large operations with thousands of acres. Lucas: It's a valid concern. The upfront cost of 5G equipment is still high for a 50-acre family farm. But there are cooperative models emerging — groups of small farmers sharing a single 5G base station and pooling data. The USDA has a pilot program that subsidizes 5G infrastructure for small farms. And as module prices drop, it'll become accessible. Luna: So there's a path to democratization, but it's not here yet. Lucas: Right. The technology is proven; the barrier is economic and infrastructure. And that's where policy comes in. The FCC's Rural Digital Opportunity Fund has allocated $20 billion to expand broadband in rural areas, and some of that is going specifically to 5G for agriculture. Luna: It sounds like the pieces are coming together. What's the one thing you'd point to as the most exciting development in the next year? Lucas: I'd say the combination of 5G and autonomous tractors. Deere already has a fully autonomous tractor — no driver in the cab — approved for commercial use in the US. When you pair that with 5G remote monitoring, a single farmer could manage a dozen tractors from a laptop. That's a labor revolution in an industry facing severe worker shortages. Luna: Labor is a huge problem. The average age of US farmers is about 58. So tech that replaces physical presence could be a lifeline. Lucas: Exactly. It's not just about efficiency; it's about enabling a new generation of farmers who may not have the manual skills but can manage digital farms. And that's where I think 5G's quiet transformation will be most profound — not in the tractor itself, but in who gets to be a farmer. Luna: That's a really compelling vision. Let's keep tracking this. Lucas: Absolutely. We'll revisit in a few months when those Iowa pilots have more data.
