Cover Crops Field Guide For Farmers Expanded, Updated

By Emma Hopkins

Farmers interested in planting cover crops to improve soil health now have an updated and expanded resource in the second edition of the Midwest Cover Crops Field Guide.

The pocket guide, released Monday (Sept. 22),is produced by Purdue University and the Midwest Cover Crops Council.

Growers plant cover crops for a variety of reasons and possible benefits. Cover crops can trap nitrogen left in the soil after cash-crop harvest, scavenging the nitrogen to build soil organic matter and recycling some nitrogen for later crop use. They also can prevent erosion, improve soil physical and biological characteristics, suppress weeds, improve water quality and conserve soil moisture by providing surface mulch.

The first cover crops guide was released in February 2012. The updated guide is in response to the increasing interest in cover crops in the Midwest and to requests for additional information.

"All this new information will help farmers better choose appropriate cover crops for their situation and better manage the cover crops they grow - all for greater potential benefit for their soils and cash crop growth," said Eileen Kladivko, Purdue professor of agronomy.

The updated guide features seven new topics:

  • Getting started in cover crops.

 

  • Rationale for fitting cover crops into different cropping systems.

 

  • Suggested cover crops for common rotations.

 

  • Cover crop effects on cash crop yields.

 

  • Climate considerations including winter hardiness and water use.

 

  • Adapting seeding rates and spring management based on weather.

 

  • "Up and coming" cover crops.

There also is more information about herbicide carryover, manure and biosolids applications, and crop insurance issues.

Four states have been added to the new guide to round out information for cover crops in the Midwest. They are Kansas, Missouri, Nebraska and South Dakota.

The guide's second edition is available at Purdue Extension's The Education Store atwww.the-education-store.com. Search by the name of the publication or product code ID-433.

EVENT PREVIEW: You Can Help Reimagine Plant Breeding at the 2024 NAPB Meeting

Martin Bohn can’t wait to welcome people to the 2024 meeting of the National Association of Plant Breeders meeting being held in St. Louis, Miss., July 21-25. This year’s meeting, hosted by Bayer Crop Science and the University of Illinois-Urbana-Champaign, promises to be one of the NAPB’s most important yet, evident in its theme Rethink, Reimagine and Revolutionize.

While the main conference will be held at the St. Louis Union Station Hotel, it will feature a tour of the nearby University of Illinois-Urbana-Champaign facilities. Bohn serves not only as co-organizer of the meeting, but as crop sciences professor at the university.

“The conference theme revolves around rethinking, reimagining, and revolutionizing plant breeding. We’ve witnessed significant technological advancements over the past decade, with an abundance of genetic, phenotypic, and environmental data becoming more accessible, alongside the integration of artificial intelligence into data science, opening up new possibilities,” Bohn says.

During the conference, attendees will examine these advancements, reassess the field, and explore how we can adapt to or leverage them. The event will feature three sessions: Reimagining, Rethinking, and Revolutionizing, with speakers delving into each theme. Audience participation is encouraged, with lively Q&A sessions expected.

The climax will be the Revolutionize session, featuring speakers from St. Louis startup companies at the forefront of plant breeding innovation, all hailing from the St. Louis Innovation Hub. It promises to be an exciting showcase of cutting-edge ideas, Bohn says. Ultimately, the conference aims to inspire attendees with the innovative work happening at the University of Illinois and beyond.

Bohn is looking forward to showing off the facilities at the university, where there exists a thriving plant breeding program. Visitors are in for a treat.

“When you’re coming from St. Louis to the university, you might expect to see a lot of corn and soybeans, but there’s much more in store. We’ve put together a diverse program featuring various facets of agricultural innovation,” he says.

“Throughout the day, we’ll showcase national initiatives focused on advanced bioenergy and bioproduct innovation. We’ll also explore autonomous farming, environmental resilience, and soil quality at two different stops.”

You’ll get a peek into the USDA Maize Genetics Cooperation Stock Center, home to crucial genetic stocks for corn breeding, and the USDA Soybean Germplasm Collection. Additionally, the tour will highlight the CornBox, a project by some of Bohn’s colleagues which is their version of a sandbox to test innovations for digital agriculture in a live corn field. Visitors will also see the breeding programs spanning soybeans, corn, small grains, hemp, and more.

“One highlight close to my heart is our organic farming systems breeding program. We’ll also tour our student farm, featuring research on vegetable production systems and how robotics aid in managing insects. And let’s not forget about our local startup companies at the University of Illinois Research Park, showcasing their latest research and products,” Bohn adds.

Visitors will wrap up the day at Riggs Beer Company, known for using locally grown seeds and grains. Their motto, “On our farm, we grow beer,” sets the tone for a relaxed Q&A session with the brewery’s owner and team, accompanied by great food and, of course, some beer.

Of course, organizing a conference like this is no small feat; it’s a monumental task that requires careful coordination and collaboration.

“Initially, I thought it would be as simple as putting together a program and inviting speakers, but it’s far more complex than that. Many moving parts need to come together seamlessly to make it a success,” Bohn says.

The beauty lies in sharing the workload among many shoulders, ensuring that no single organization or individual bears the burden alone. The meeting is being co-hosted by Bayer Crop Science.

“Working together toward a common goal of hosting the best conference possible is a tremendous opportunity to build relationships. I truly believe that the connections we forge with our colleagues and partners at Bayer will endure beyond this event,” Bohn says.

“Working with Bayer has been eye-opening. While we often operate within the confines of academia, collaborating with a company brings a fresh perspective on what matters in the real world. It’s invigorating to explore shared interests and embark on collaborative projects together.”
