Cover Crops- It is Amazing how much interest there is these days!

It is amazing how much interest there is in cover cropping these days!

Sarah Carlson from Practical Farmers of Iowa and I were discussing this fact in Omaha, NE earlier this week.  To think that there would be a conference like we attended in Omaha was almost a “dream” when we were attending some of the first Midwest Cover Crop Council Meetings less than 10 years ago.  Many thanks to Eileen Kladivko, Dale Mutch, Dean Baas, Tom Kaspar, Anne Verhallen, Alan Sundermeier, and others who set the pace and path and vision for sharing and researching the benefits of cover cropping.

I had the privilege of speaking to over 1,000 farmers at the National No-Till Conference in Springfield, IL in January 2014. Being a long-time no-tiller; this was a highlight of my career.

So, where am I these days?  (kind of like “Where’s Waldo?)  Over the past seven weeks I have  spoken in many states (NY, OH, WI, NE, MI, etc…) and at Ridgetown, Ontario.  I have spoken to well over 2,000 producers these past 50 days.  I keep telling my wife I’ll check in as often as possible and I try to keep the kids aware of where I am and where I am going (I use this as great geography lessons!).  The interest in cover cropping is astounding.  I am excited to see so many producers that are using cover crops are excited about what they are doing…I am 100% confident this is NOT a fad.

I have a few more cover crop meetings to add that you might find very interesting.

On March 5 at 10AM I am speaking at the Yahara Pride Farms 2014 Watershed-Wide Conference: Building on our Progress at  Lake Windsor Golf Club  4628 Golf Road, Windsor, WI 53598  For more information contact: rachel@yaharapridefarms.org; 608-255-6329 ;  www.yaharapridefarms.org.

Starting on March 6 the American Society of Agronomy is conducting a number of Cover Crop webinars.  The speakers on the presentations are among the “who’s-who” in cover cropping research and practice.  Please register and watch these free webinars!

On March 13 I will be speaking at the Bay County  Soil Conservation District’s Soil Health and Cover Crop Meeting in Pinconning, MI.  This meeting involves some excellent speakers on soil health and also on local cover crop research.

Also in Wisconsin I am speaking at three Legacy Seeds Cover Crop Seminars.  Please contact the folks at Legacy Seeds at karen@legacyseeds.com to preregister.  Registrations starts at 9:30 and the meetings start at 10 AM.  Early order “discounts” will be available.  Lunch will be served at each location.

March 18 at  Jakes Northwoods 1132 Angelo Rd. Sparta, WI  608-269-5010

March 19 at the Eagles Club 2588 hwy. 53 Chippewa Falls, WI 54729 715-723-0172

March 20 at  Cobblestone Creek Dining and Banquet Center 740 West Ryan St. Brillion, WI 54110 920-756-3214

On April 1 Winnebago Soil & Water Conservation District and AgTech are sponsoring a Cover Crop Workshop in Durand, IL.  I am honored to speak at this event.  There is an optional field tour after lunch.  Preregister by 3-25-14.

On May 9 There is a Soil Health Field Day – Sponsored by Catawba SWCD in Newton, North Carolina.  I will not be attending this meeting but it sure sounds like a great day!   Thanks to Russell Hedrick for passing this along.

Also, sometime in April – Robison Farms (my brother Don and I along with mom and dad) hope to host a field day at our Greenwood, IN farm where we have 5 acres of replicated cover crop research.  More details will follow soon on this.

These are exciting times in Agriculture.  Remember to be thankful for those who have come before us and for those who share their knowledge and vision with us.  More importantly share your vision and knowledge with others.  Most importantly, be thankful to the God of Creation who gives us the responsibility to care for His creation.

Advancing Cover Crop Adoptions Research Agenda

Advancing Cover Crop Adoptions Research Agenda

IMG_3507
Will corn planted after cover crops consistently out-yield corn planted without cover crops? Research has shown some nice advantage in areas. More research should give farmers more confidence in cover cropping.

Sarah Carlson, Midwest Cover Crop Research Coordinator with  Practical Farmers of Iowa and Ryan Stockwell, Agriculture Program
Manager with the National Wildlife Federation have written an agenda that will help researching cover crops be more scientific over the next six to eight years.   The research agenda is published in the Journal of Agriculture, Food Systems, and Community Development
ISSN: 2152-0801 online www.agdevjournal.com

Here is the abstract of this aggressive agenda:

Abstract
Given certain ecologic and agronomic characteristics of conventional corn and soybean monocultures, cropping systems reliant solely on these two commodities inevitably lose soil and nutrients.  Leaky cropping systems not only hamper society with negative externalities, but also erode the very natural resources needed to produce food and sustain civilization. The United States Department of Agriculture (USDA), state agriculture department staff, farmer organizations, agribusiness leaders, and conservation and environmental organizations now see cover crops as a solution to reduce the negative externalities of conventional row-crop agriculture. Farmers are asking for increased agronomic and economic research to help them understand the benefits of and implement the use of cover crops. Researchers for the most part are not keeping up with farmers’ innovations on cover crops nor on providing the information sought by farmers. This article outlines the questions farmers are asking about cover crops and provides suggestions to agronomists, soil scientists, and researchers on research topics to best answer those questions. Additionally, social scientists must initiate a new round of research to understand the underlying concerns farmers have with cover crops and help to define the information (both content and source) that best informs and influences farmers. This article outlines specific issues and questions social scientists can research to contribute to the advancement of more sustainable farming practices and, in particular, cover crops.

Cover Crops are Working in Iowa

Cover crops are working in Iowa!

While that may not mean much to my eastern corn belt friends it means a lot in Iowa and the upper Midwest.

Working with Sarah Carlson from Practical Farmers of Iowa and Tom Kaspar from ARS at Ames, Iowa, we’ve been attempting to identify what cover crops will be most compatible with common Iowa farming practices – in particular the use of longer season corn hybrids and soybean varieties, as well as an abundance of corn after corn (CAC) management strategies. Establishing cover crops like radishes and annual ryegrass into these situations hasn’t proved to be easy.

Aerial application of cover crops (annual ryegrass, crimson clover, radishes, etc.) into corn in Ohio and Indiana has been very successful. However, in Iowa it has not worked with quite as much success.  Cereal rye may actually be the best alternative. While it may seem a bit “simple” to plant mainly cereal rye most years, there are significant benefits to using cover crop rye in a corn after corn scenario, mainly because it has been shown to reduce Goss’s wilt.

September 5, 2011 planted Annual Ryegrass compared to Winter Cereal Rye in central Iowa in April 2012. Note the dramatic difference in winterhardiness.
September 5, 2011 planted Annual Ryegrass compared to Winter Cereal Rye in central Iowa in April 2012. Note the dramatic difference in winterhardiness even after a very mild winter.

Sarah commented that besides using more winterhardy species for greater success, it is also very important to not interseed the cover crops into green corn or green soybeans.  She says, “Pushing radishes with aerial seeding into a dense, dark corn or soybean canopy is unsuccessful.”

But if the right cover crop is used in Iowa and managed well then covers work very well!  Rod Swoboda from Wallaces Farmer published an article written by Sarah Carlson reflecting work that was overseen in Iowa by PFI.

 

 

 

 

 

 

Cover Cropping North of I-80 After Corn & Soybeans – A Whole New World?

There is a lot of Iowa and Minnesota and Wisconsin above I-80. Is this all part of the “no cover crops works here after corn and soybeans” zone? Maybe not!

Sarah Carlson from Practical Farmers of Iowa reminded me that cover cropping north of I-80 is different than cover cropping in northern Indiana.  She’s right.  But how different is it, and why is it different?

Sarah is quoted in a very good article in Corn and Soybean Digest that helps explain the differences.

Several farmers in Wisconsin and northern Illinois are having cover crops aerial applied with good success. But I agree with Sarah; there are still challenges.

Cover Crop Challenges in the North

This field of Annual Ryegrass is in SE Wisconsin and was aerial applied into standing corn in the fall of 2011 with great success.

I see the following challenges to using cover crops North of I-80 after corn and soybeans:

  • Shorter growing season after corn and soybean harvest
  • The use of “full season” (for the region) soybean varieties and corn hybrids to maximize yield potential
  • Fear using winter cereal rye (their best option after corn and beans) because of potential risks
  • Fewer choices for cover crop species to use
  • Harsh winters and less snowfall to protect smaller cover crop plants

Cover Crop Opportunities in the North

  • More aerial applicators successfully flying on cover crops into standing corn and soybeans
  • Improved yields following winter cereal rye, a crop that can be planted late
  • High yields and profit with shorter season corn allowing timely application of cover crops
  • Annual Ryegrass is working well in southern Wisconsin and southern Michigan and there are many positive results from using it.
  • Dixie Crimson Clover has a good history of surviving the winter even in mid-Michigan and southern Wisconsin.
  • Late planted Austrian Winter Peas are overwintering as far north as the top of the Thumb of Michigan.
  • Winter Barley (winter hardy varieties) is surviving well in southern to mid-Wisconsin and in southern Minnesota and used for a cover crop or haylage before planting corn silage.

While not every producer North of I-80 will have success with cover crops after corn and soybeans, there are a number now that are happy with their results.

My message is to use wisdom and best management practices.

IF you want to try cover crops after corn and soybeans and you are north of I-80, realize that you are not the first person to try it.  Many have gone before you with good results.

Don’t give up before you investigate the possibilities.

Now, if you are north of I-90…
