Cover crops help expand cattle operation

Slideshow: Expanding last season’s cover crop trial would add pastureland and cut feed costs, among other benefits.

With three sons who might one day take over the family farm, Todd and Michelle Andresen are advancing plans to expand their beef operation without buying more land.

The Andresens run about 1,500 acres of grain, grow about 300 acres of hay and raise 110 cow-calf pairs of Red Angus cattle on about 400 acres of pasture north of Detroit Lakes, Minn. Expanding last season’s cover crop trial would add pastureland, extend the grazing season, cut feed costs and — once established — help to alleviate the excess spring moisture that often delays planting.

The initial trial started with a 27-acre wheat field. On the cover crops planted into the post-harvest wheat stubble, the Andresens grazed cattle for 10 days in November.

Environmental Quality Incentive Program (EQIP) assistance from USDA’s Natural Resources Conservation Service reduced the risk of trying a cover crop. Clean Water Funds from the Minnesota Board of Water and Soil Resources covered part of the fencing costs. Becker Soil & Water Conservation District and NRCS staff offered technical assistance.

“We want to grow that end of our operation, and I think [how we’re going to do it] has got a lot to do with these programs,” Todd says. “We can grow our livestock end without a lot of capital expense. We don’t need to purchase more land or rent more land. We can utilize the land we have now with cover crops — full-season cover crops or cover crops after we harvest our wheat or corn — and just grow internally.”

That might mean expanding to 150 or 200 cows — maybe more depending upon what their oldest son decides to do after he graduates from high school this year. Michelle’s primary responsibilities center on the cattle. She also helps with fieldwork. Each son owns a few cattle.

Rotational grazing begins

In August 2019, the cattle grazed on land previously enrolled in USDA’s Conservation Reserve Program. The Andresens bought the CRP land about six years ago, intending to use it for pasture.

“I knew nothing about rotational grazing,” Todd says. “We’d never done it. So, we started with 152 acres, fenced the whole thing, made it into six paddocks, put in 7,000 feet of waterline and six water tanks.”

EQIP assistance provided a rotational grazing payment.

Once the property was fenced and water was installed, the paddocks opened to rotational grazing about four years ago. The grazing contract with NRCS expired in 2019. The Andresens are continuing the practice on their own.

“We see the huge benefit in what’s going on there,” Todd says. “The best benefit is we can have more animals — cow-calf pairs — per acre than we could in the past. We are utilizing our grass in a timely fashion and keeping our heights of grass to a manageable re-growth state.”

The cattle also graze on rented acres and on nearby U.S. Fish & Wildlife Service land. Through an NRCS delayed haying program, the Andresens converted 25 acres of marginal cropland to pasture. Planted with native grasses, it can be grazed after Aug. 1.

This season’s cover crop plans extend to 300 acres of wheat, which will be seeded with no-till cover crops after harvest, and then planted with no-till corn in 2021. That EQIP application to expand cover crop and no-till practices has been submitted.

Todd also plans to expand an on-farm experiment with planting 60-inch-row corn. Last year, he planted four acres of 60-inch rows to evaluate cover crop seeding and yield.

“It’s a challenge with 30-inch-row corn to get cover crops established,” he says. He read about 60-inch rows online and thought he’d give it a try, anticipating that his cattle would be able to graze cornstalks in the fall and cover crops, too.

Evaluating trial success

After he did the math, Todd deemed the cover crop and the 60-inch corn trials a success, even though both had challenges. A late wheat harvest delayed planting the cover crop and the 60-inch-corn fared somewhat worse than the 30-inch-rows in a windstorm that flattened a field and took out a barn.

Although the season was shorter than anticipated, Todd says that grazing the cattle on the cover crop for 10 days saved $2,000 in feed costs. An earlier cover crop planting and later snow could extend grazing to 30 or 40 days. Although the test-plot wide-row corn yield was about 8 bushels per acre less, Todd figured the value of a cover crop interseeded in the more widely spaced corn rows would more than compensate.

Continuing each year with the fields planted to wheat, the Andresens plan to slowly expand cover crops and no-till practices.

“Every person says start slow. I would love to jump in with two feet, sell my tillage equipment, get to no-tilling. I don’t believe that’s a very smart move on my part at this point. There’s a lot of things that have to cash flow to make this operation sustainable,” Todd says. “So, we’ll start slow. As we see things working, we’ll continue to grow.”

Todd bought a no-till drill this spring. He had to travel to Iowa to find one and plans to make it available for neighbors to rent.

“We’re excited about switching and doing things differently,” he says. “This investment was a big investment. This put me in the forefront of ‘We’re going to do this.’”

NRCS district conservationist Ed Musielewicz says farmers like the Andresens are the key to making practices such as cover crops and no-till widely accepted.

“Finding that one person [who] is willing to take some sort of a jump in doing it really helps locally in getting practices implemented across the landscape,” Musielewicz says.

Across the farm as a whole, the Andresens’ biggest challenge has been excessive spring moisture, which delays planting.

“That’s why tillage has been such a big part of our operation, because it dries out our soil and helps us get out there in the spring,” Todd says. “My goal is to have cover crops growing to help dry the soil out in the spring and get in there in a timely fashion.”

The farm’s big-picture goals involve growing soil health, eliminating erosion and controlling water.

“If we really look back at rotational cropping systems and livestock systems that were here 60 years ago when every mile had a farm on it, that’s what they were naturally doing is growing cover crops and grazing. I want to get back a little bit more to having healthier soil,” Todd says. “We could maybe have better water infiltration systems that would help these soils and try to grow soils, instead of taking away from them all the time.”

Delayed corn harvest produces new mindset

When a terribly wet harvest season made it impossible for Todd and Michelle Andresen to finish combining 200 acres of their 600-acre corn crop in 2019, it forced another fundamental shift in thinking.

“We always get our corn combined in the fall, and we always get our ground worked,” Todd said in late March. “At whatever cost.”

That meant harvest continued, no matter the labor cost, fuel cost or drying cost.

“We just didn’t get it done this year,” he said. “That’s very stressful. You feel like almost a failure.”

This season, he finished combining in late March.

“It went wonderful,” Todd said.

The corn was drier, which saved drying costs. The test weight was better. This spring, the Andresens were considering no-till planting into the corn stalks.

“That’s a huge lesson,” he said. “We can do this different. We’ll have to deal with stalks, but we’ve already saved so much money.”

Even if the yield dropped from 40 to 35 bushels per acre, he estimated they would come out ahead because of savings in propane, time in the tractor and wear-and-tear on equipment.

Fall harvest remains a goal. But the Andresens’ outlook has changed.

“That’s a major lesson. It doesn’t have to be at all costs,” Todd said.
