Plant Cover Crops

Learning about the benefits of planting cover crops.

Cover Crops in the Northland

New articles out on Cover Crops in the Upper Midwest

During the week of March 18-21 I spoke at the Legacy Seeds Cover Crop Meetings to over 150 people in three Wisconsin towns

Appin Turnips make an outstanding cover crop and forage crop too!

about cover crops.  During each meeting I showed why folks should consider using cover crops (erosion control, nutrient management, compaction reduction, aeration/infiltration, etc…).  I also implored producers to be creative about applying cover crops (aerial application, Hi-boy type spreaders, maybe interseeding into short corn, etc…).  Lastly I showed how many farmers are reporting increased profitability by using  cover crops.

Many farmers attending the meetings had at least some experience with cover crops and those that talked to me personally had very good experiences.  It was fun to talk to farmers that are excited about both soil health and profitability.

At the meeting in Sparta, Agri-View Newspaper Crops Editor, Jane Fyksen was present and taking notes for a story she was writing for the publication.  Jane did a great job in her reporting of what I said.  I want to share those articles with you.  The first article is entitled “Finding a cover crop mix to fit every need” and the second one is entitled “Aerial and overseeding of cover crops: Making it work“.

I have conducted over 40 cover crop talks this year from Omaha to Ontario and from Syracuse, NY to Chippewa Falls, WI.  I am amazed how far this cover cropping idea has come.  I am also very excited to see what will happen in another 8-10 years.

I cannot wait for warmer temperatures so we can see what cover crops survived this past record setting-cold winter.

More Fall Cover Crop Field Days Coming

This fall there are more cover crop field days to attend in Iowa and Wisconsin.

 

For those in Iowa see http://practicalfarmers.org/blog/2013/fall-2013-cover-crop-field-days-scheduled

In Wisconsin there are two field days:

There will be opportunities to look in soil pits in Northern climates to see just what is going on beneath the surface of the soil.

Cover Crop Field Day Set in Blooming Prairie, MN

PileDriver at Hagan Farms 2 33 days
This Radish was planted in late July 2013 and after 33 days has tremendous growth. This mix included oats and crimson clover and radishes.

Cover Crops will be the main topic of discussion on September 4, 2013 at a cover crop field day and meeting in Blooming Prairie, MN. I have the privilege of speaking at this event as we look at cover crops on prevented plant acres.  We will also look at what cover crops work best in the upper Midwest.  We will be on Brad Hagan’s family farm and possibly look at Dale Ramsey’s farm too.  Please note that we will be looking in root pits (where the action really is)!

I received this note from Legacy Seeds representative Andrew Heath about the field day/meeting:

“We  plan on structuring the event much like an open house with designated times where you will be able to address the crowd. We will start the event at 10 am and have you speak from 11 to 11:45 and again at 1 to 1:45. There will also be transportation to the cover crop plot and some of the field that you, TJ, Brad and I visited earlier with root pits dug. This will happen from 12 to 1 and 2 to 3.”

I have seen the plots and have added photos here on this post to entice you to come if you are in the region.

As a side note, Hagan farms will be no-tilling corn into these fields in 2014.  We’ll follow-up on these fields next spring and see how these fields compare to others that did not have a cover on them.

This prevent plant field had plenty of nitrogen from manure to capture. Hagan farms used a hybrid brassica and spring barley to secure the nitrogen and Berseem clover to produce more N and provide better soil health.

Cover Crops to the Rescue!

A Huge Problem

Recently I was in Minnesota with Brad Hagen, T.J. Kartes, and Andrew Heath looking at Brad’s 1,000+ acres or cover crops.  Brad had not intended on planting any of theses acres to cover crops in July, 2013…his intentions were to plant them in August or early September.  But spring 2013 rains and floods kept Brad from planting corn or soybeans on most of his 1,700 acres near Ellendale, MN (about an hour SW of Rochester, MN ).  Brad attended a cover crop meeting TJ set up for me to speak at on behalf of Legacy Seeds last March and as I spoke I could see Brad’s mind working.  When the spring rains came so did phone calls from Brad to TJ and from TJ to Andrew or me (or both)…”what can I do to build soil during this disaster?” was the theme of the weekly (if not daily) phone conversations.

Cover Crops to the Rescue!

Brad’s goals are to build soil and to scavenge nitrogen from his hog operation and build nitrogen with legumes.  Realizing that we would plant in early-mid July and not in mid-late August we all understood that we did not want to have to mow to remove seed heads if at all possible – so we left Radishes out of the mix.  We also realized that we wanted to use a “summer” clover, so we used Berseem Clover for it’s excellent growth and N producing ability.  We chose Oats as the grass in most fields and then we added a twist, Pasja or Vivant Hybrid Brassica.  I have worked with Pasja for over 10 years and rarely ever saw it produce a seed head in the summer or fall.  While Pasja (nor Vivant) have a big tuber like a Radish they do have the ability to scavenge a tremendous amount of nitrogen and earthworms dwell around their roots.

In some later July (and soon to be mid-August) planted fields we chose to use Spring Barley and Crimson Clover along with PileDriver Radishes and Appin Turnips.  TJ and Brad requested this mix so we’d get later fall growth, deeper penetration through compacted soils (Radish vs. Pasja/Vivant) and excellent N production from the Crimson clover.  Spring Barley was available and many folks in Kentucky have told me that barley makes the soil “sweet” (whatever that means).  From experience I know that soil after Barley is quite mellow.

Early August Report

From what I saw on August 1 I was very impressed!  As other folks in the region were planting straight Oats or possibly a few were adding Radishes very few other folks seemed to totally share Brad’s goals.  Brad told me that he is doing these cover crops because he wants to build his soil and because he wants his 7 year old son to have better soil to farm when he grows up and farms his place like Brad does with his father.  I’ll have more photos in a month or so.  I believe Andrew, Brad and TJ will plan a field day for September.  It’s beautiful country near the Hagen farm…it probably will be worth the drive in September to meet Brad and his family.  They’re pretty special folks…

Take a look at my You Tube channel “covercropdave” to watch an interview I have with Brad and TJ.

Cover Crop and Forage Meeting Aug 14, 2013

On August 14, 2013 the University of Wisconsin is holding an Agronomy Field Day at the Marshfield Ag Research Station.   The line-up of speakers looks outstanding and CEU credits are available for Certified Crop Advisers.

I will be speaking out at the cover crop plots looking at how we can use cover crops as forages and benefit the soil at the same time.

KY Forages April 2011 041
An Annual Ryegrass cover crop can make excellent dairy quality baleage/silage in the fall if planting after wheat. It also is a fabulous scavenger of N and P with deep roots.

For past blog posts on using cover crops for forages looks here and here.

Cover Crops in Wisconsin – Full Speed Ahead!

This cover crop field was ready for harvest in late September 2012.

I took a new management position in May of 2012 with Wisconsin based Legacy Seeds, Inc.

While my main responsibility lies in working with alfalfa and forages I also was pleased to find out that there were several folks in Wisconsin that were using cover crops!  Well, you would figure that I’d get involved more with cover crops in the Badger state, and I have.

Wisconsin Cover Crop Meetings

In February 2012 I conducted two cover crops meetings in the Fox Lake, WI area with over 75 producers present. The purpose of these meetings were to teach farmers about how cover crops can work in their farming operations.  I was very pleased with the outcome of those meetings as over 10,000 acres were planted on farms that were represented at those meetings.

In July I held three more cover crop meetings in Eau Claire, Waupaca, and Brillion, WI. All combined, there were over 150 farmers present and I’m confident that there were at least 30,000 acres of cover crops planted by those farmers.

While I don’t have figures of how many cover crops were planted in Wisconsin, I think there were as many as 250,000. Many of those acres were after wheat was harvested and a surprising number after corn and soybeans.

Cover Crops for Forage & Manure Management

Feed was one reason so many acres were planted. The severe drought has created a forage shortage.

But many farmers planted their cover crops because they want healthier soils and better production.  Still others planted because they want to hold onto the nutrients from their manure.  Whatever the reason, cover cropping is alive and well in Wisconsin – and growing.

You can click on the pictures below to see a larger image of each.

The Oats, Appin Turnip and Cowpea combination should make excellent haylage for the Wisconsin dairy market.
The nodules on the Austrian Winter Peas were multiple and large. This field will be planted to corn next year and it sure appears that a good amount of nitrogen will be in the soil and available for that corn crop.
This field of Austrian Winter Peas and Radish east of Green Bay, WI was planted after wheat in severe drought conditions. Thankfully some later rains came to get the mixture up and going.

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…
