Conservation tillage can provide a lot of benefits. It increases water filtration, reduces erosion, and improves soil productivity. But some farmers worry about weed control challenges and lower yields. University of Minnesota extension specialist Jodi DeJong-Hughes joins Zach and Mitchell to talk about conservation tillage, including a recent study she did assessing different tillage practices. And North Dakota farmer Mik...

In this episode, you’ll learn about our hosts and what drives their interest in sustainable agriculture. Zach Johnson, a farmer near Alexandria, Minnesota, also hosts the popular MN Millennial Farmer series on YouTube. Zach’s experiments with cover crops and conservation tillage have been a “disaster” so far. But he really wants to figure out how to make them work. Meanwhile, co-host Mitchell Hora has seen a lot of success...

We explore the benefits and downsides of drain tile with Rodney Rulon, an Indiana farmer, and Matt Helmers, the director of the Iowa Nutrient Research Center at Iowa State University. Drain tiles dry out and warm up fields, boost productivity, and extend growing seasons, which can make them important economically. But they can also have negative effects on water quality. Zach and Mitchell talk with their guests about how t...

Sometimes the hurdles to sustainable practices come from people right in a farmer’s network: family, landowners, neighbors, seed dealers, and lenders. Bryan and Lauren Biegler, farmers in Minnesota, join Zach and Mitchell to discuss how they fought back the image of being “hippie farmers” as they started strip tilling and planting cover crops. Mollie Aronowitz, a land manager at the People’s Company in Iowa, and Randy Dell...

Nutrient management is an art as much as it is a science. And nitrogen, in particular, can be a difficult nutrient to manage. Understanding how it behaves in soil systems can help farmers increase its uptake and minimize nitrogen loss to the environment, where it can pollute water. University of Minnesota extension specialist Brad Carlson and Minnesota farmer Mark Bauer have been working together for years to figure out th...

Many farmers have heard the alarming statistic that we’re losing topsoil to erosion about 10 times faster than it can be replenished. We want to keep our soil healthy and intact so we can continue farming and be more resilient in the face of increased severe weather events. In this episode, Zach and Mitchell talk to Jim Isermann of the Soil Health Partnership, an initiative of the National Corn Growers Association. Jim tel...

Cover crops blanket the soil from the time you harvest one crop until you plant the next. And there’s a long list of benefits they provide: they can replenish soil in between planting, prevent soil erosion, slow water down, pull moisture deeper into the soil, and increase soil organic matter over time. For Doug Adams, an Iowa farmer and soil conservation technician at USDA-NRCS, cover crops also provide a way to recycle hi...

There are a lot of technologies available these days like sensors, geo-mapping, robots, and all sorts of other big data tools. The idea behind them, of course, is to make farming more efficient, and ultimately more profitable. Those technologies can also help growers farm more sustainably. Mitchell and Zach talk with precision ag expert Raj Khosla and Illinois farmer Michael Ganschow and try to parse how good some of the t...

Many farmers care about soil health, water quality, and about being good neighbors to each other and to people in nearby towns and cities. But sometimes it may feel like what farmers do individually doesn’t make much of a difference. In this episode, Zach and Mitchell talk about what it looks like when farmers start working together, as well as with others in their watersheds. Iowa farmer Ray Gaesser, Texas A&M researc...

Field Work host Zach Johnson has tried planting cover crops a few times on his heavy clay soils in Central Minnesota, but has had nothing but failures. In this episode, Ken Franzky, an agronomist with Centrol Crop Consulting, gives Zach some insights into how to try again. Ken tells Zach and Mitchell that his recs on aerial applications, herbicide rotations, and seed mixes vary a lot by geography. “I haven't seen a cov...

We know that corn and soybeans are the most economically viable crops we have on farms, at least in the Midwest, and that’s why they dominate the ag systems here. But there are efforts underway to add in a third crop. Third crops can be helpful for breaking up weed cycles, fixing more carbon and nitrogen in the soil, and possibly even increasing yields. Zach and Mitchell talk with farmer Darin Voigt along with Nick Jordan,...

For our last episode of the season, we bring you our first live show ever, recorded at Farmfest in Morgan, Minnesota. Zach and Mitchell round out the season by bringing back some pals you heard from in earlier episodes, including their dads. Nathan Johnson and Brian Hora reflect on how their challenges with farming have been different from their sons’ and how the new generation is leading the charge of experimenting with s...

Farmers Zach Johnson and Mitchell Hora are back with more honest and authentic conversations about the ups and the downs of sustainable agriculture. They’ll explore how farmers’ failures with cover crops and strip till can give way to revelations, and how producers on the frontlines are figuring out how to pay for costly technologies like bioreactors to make their farms more sustainable. This season, Zach and Mitchell also...

Field Work hosts Mitchell Hora and Zach Johnson kick off Season 2 by catching up on what happened in their fields since they last met up in the studio. Zach tells Mitchell last fall was full of challenges due to constant rain. Down in tropical Iowa, Mitchell’s harvest was pretty uncomplicated. They discuss the new things they’d like to try this year and important considerations, like how to properly pronounce the word “whe...

The “New Mexico Milk Maid,” Tara Vander Dussen, reaches people around the world with her social media posts shedding light on the dairy industry. She’s even had the chance to speak before the United Nations Food and Agriculture Organization Committee on World Food Security. Tara tells Zach and Mitchell about the challenges of farming in the dry southwest, the latest sustainable technologies on dairy farms, and what it’s li...
