Finding the right seeding method – which option is best for you?

ILFHeaderJust ask Clayton County farmers Mark Glawe, Dan Keehner and Brian Keehner! Each have explored different seeding methods and shared their tips for successful cover crop management at our field day on November 29th in Luana. Although their soil types, crop rotations and seeding method vary, they share similar goals for using cover crops in their operations – improved soil health and reduced nutrient losses.

Mark Glawe began using cover crops in his no-till system near Elkport in 2006 to address soil erosion concerns on his steep slopes. In early September, he seeded about 2/3 of his acres aerially with oats, rye, radishes and rapeseed. These acres are grazed by his cattle herd following harvest and again in the spring. This year, Mark turned his cattle out in October and estimates his additional forage value at $35/acre. In addition to the aerially seeded acres, Mark’s son follows the combine on the remaining acres to drill cereal rye to keep the steep slopes covered between crop seasons.


Dan Keehner first started with aerially seeded cover crops in 2013 on his ground near Monona. Noting disappointment with the consistency of the stand, he hired the cereal rye cover crop to be drilled after harvest in 2014. Similar to this fall, harvest was delayed and the drilling wasn’t completed until mid-November. With limited fall growth but more consistent stand, Dan decided to set up his own cover crop seeding rig for 2015.

Using his vertical tillage implement, Dan mounted an air seeder to seed the cover crop himself following harvest and has covered all of his acres with a cover crop since 2016. He uses both cereal rye and winter wheat to keep the ground covered until planting of his cash crop in the spring.

“I love seeing one crop (cover crop) go down and another (corn/soybeans) come up. You know when you get the rains, that soil is protected,” stated Dan.


Similar to his cousin, Brian Keehner has tried multiple seeding methods but wasn’t satisfied with the results. Through custom innovation, and discussion with a cover crop user in Indiana, Brian has modified his combine with an air delivery system on his corn and soybean heads to seed the cover crops while harvesting. This method fits the needs of his operation by saving time, labor and fuel by combining passes. His next goal for the system is to increase his seed carrying compacity to reduce the number of refill stops.

Regardless of how they seeded their cover crops, all three producers reported 0.5-1.2% increases in their soil organic matter over a five year time-frame. The combination of no-till and cover crops has led to the retention and building of soil organic matter on their lands. The building of organic matter helps improve water holding capacity and retention of soil micro-nutrients needed for crop production. With healthier soils, we have healthier crops and water!

AreSwanson Cattle_Cover Crop2 you interested in grazing cover crops?

Here are some helpful ideas shared by Don Swanson, Henry County Farmer, and Patrick Wall, ISU Extension and Outreach Livestock Specialist, at our field day near Agency on November 20th hosted by the Swanson Farm Partnership on their Heritage Farm.

  • Being organized and ready when the conditions are right to get it seeded in the fall.
  • Use the Pluck Test for turning out cattle
    • If you pull on the rye and the blade breaks free while the roots stay in the ground you can turn the cattle out. If the roots come with, best to wait.
  • Establish a good fence with high-tensile wire and flex posts
  • Cover crops add forage diversity for dry years when pastures and hay are in short supply
  • Fall Grazing  – oats
    • Grows quickly following early season harvest of silage, seed corn or early maturing soybeans, will winter kill
  • Spring Grazing – cereal rye
    • Winter hardy and will generate majority of biomass in the spring
  • Start small – corn acres going to soybeans in the spring #CoverYourBeans

“Getting an extra 30 days of grazing in the spring on cover crops is part of the plan to make cover crops work economically when cost share is done,” stated Don.

New online tool helps farmers assess value of cover crops

Iowa State University Extension and Outreach, in partnership with Practical Farmers of Iowa, has launched a new Ag Decision Maker tool on their website to help crop and livestock farmers assess the economics of cover crops in their operations.20150428_092027

The Economics of Cover Crops tool consists of three in-depth budgeting worksheets designed to help farmers analyze the costs and benefits of cover crops – and paths to profitability – in their row crop operations with or without the integration of livestock:

  • Cover Crops Budget looks at the economics of cover crops in systems without grazing or harvesting
  • Grazing Cover Crops Budget estimates the costs and benefits with grazing or harvesting for feed
  • Grazing Cover Crops Results uses farmers’ farm data to calculate the actual economic value of grazing or harvesting cover crops from the prior year

The unique three-in-one tool was developed to let farmers see the potential added value they could gain when cover crops are used for forage. Recent Practical Farmers of Iowa on farm research has found that, when properly managed, grazing cover crops can result in sizeable profits within the first year.

The worksheets are available online and were created with funding by Iowa Department of Agriculture and Land Stewardship’s Water Quality Initiative.

Help available to use the tool

To ensure farmers feel confident using the new tool, Meghan Filbert, Livestock Coordinator with Practical Farmers of Iowa, is available to help farmers gets started. Contact her at (515) 232-5661 or meghan@practicalfarmers.org with questions or to request assistance working with the tool.

From the Archives: Conservation Chat Podcast with Farmer Nathan Anderson

The Conservation Chat podcast is taking a break for the next few months, but I would like to take you back through our archives on a tour of the “Best of the Conservation Chat Podcast.” There are 38 great podcast episodes to choose from – what’s your favorite?

nathan-and-father-randy

This month, take some time out to listen to Conservation Chat Episode 28 with Cherokee County farmer Nathan Anderson. Nathan’s interview with host Jacqueline Comito sheds light on a common problem that many young Iowa farmers are facing: how to make the transition back onto the farm.

“It takes people like my dad who are willing to let somebody come back into the farming operation,” Nathan said of his father. He recognizes that his father made sacrifices, including “[forgoing] some of that income, and also [letting] me try new things that maybe he doesn’t agree with or doesn’t know about.”

Livestock is an early entry point for the next generation to begin or return to the farm. Nathan raises a cow-calf herd with his father and was given the opportunity to try new practices including rotational grazing, cover crops, increasing herd size and changing herd genetics to favor cattle that could utilize certain pasture resources. Nathan has fire in his belly for conservation and farming, but he also recognizes that it’s important to be patient.

“This farming world that we work in, there are a lot of things that we might want to do and we can’t have them all right now,” Nathan commented. “It’s a practice of patience. Patience is active. If you’re being patient, you have to work at it.”

Webinar Recap: Whiterock Conservancy Shares Innovative Pasture Management Ideas

Webinar2

Did you miss our webinar last week with Rob Davis of the Whiterock Conservancy? We experienced technical difficulties on the day of the webinar; however, our archived version of the webinar includes better quality audio and some video of our presenter. Watch the webinar here!

Webinar1Whiterock Conservancy is a non-profit land trust of 5,500 acres located near Coon Rapids along the Middle Raccoon River. Most people may not realize that Whiterock is Iowa’s third largest recreation area in the state. In addition to its conventional cropping and pasture systems, visitors to Whiterock can explore prairies, pasture, woodlands and savannas through a network of trails.

Whiterock incorporates recreation into its pasture system by offering campgrounds and trails that are suited for hiking, mountain biking and equestrian use. They also host guided walks, tractor rides and Sunday drives through pastures with gators and ATVs.

For its 395 acres of permanent pasture land and 125 acres of savanna, Whiterock uses a variety of approaches to management including rotational grazing, management intensive grazing and conservation grazing.

Whiterock has also sectioned the pasture into 640 feet wide fencing alleyways, added filter strips around the ponds and installed a water line with a stub outs every 150 feet. Rob even considers cattle as a “tool” that can help control and trample dominant and invasive species like thistle.

One interesting approach Rob has tried is diversifying Whiterock’s pasture by mixing both warm- and cool-season species.

“We do have a couple demonstration areas where we’ve done a warm-season prairie seeding on a couple of our pastures. Most of those were flops. Those were seeded in 2009 and for whatever reason, whatever was seeded in 2009 on a couple of different seedings did not turn out well. But, when we grazed that in the end of May 2014, grazed that cool-season nearly to the ground, left two inch stubble, the warm-season community popped, even five years after that original seeding.”

Rob says that although he gets some funny looks when he pitched the idea of warm- and cool season pastures, he’s found a way to manage it at Whiterock. He uses small-scale prescribed burns, overseeds the warm-season in February or March and then encourages the warm-season community to grow by allowing high-density grazing over a period of days.
