Cover Crop Benefits

Feb 28 2014

Broadcast Recording Available from National Cover Crops Conference

Folks,
I was privileged to attend and also speak at this conference.  Please take some time to look in on the many awesome presentations that were presented in Omaha.  Dave
Broadcast Recording Available from National Cover Crops Conference

 

To meet some of today’s biggest challenges in agriculture, including rising food demand, a shrinking land base and climate change, farmers should be encouraged to adopt a holistic approach to enriching their most valuable resource – the soil – according to a panel of experts who helped open last week’s National Conference on Cover Crops and Soil Health.

 

“Cover crops to me are just the next natural step in trying to have a broader system, and I think the single biggest issue we have as farmers in this country is we don’t farm with a system in mind,” said panelist Howard G. Buffett, a philanthropist and Illinois farmer.

 

To learn more, watch a recording of opening sessions from the National Conference on Cover Crops and Soil Health, held Feb. 17 – 19 in Omaha, Neb. Joining the 300 farmers, scientists, and industry and government representatives who met in Omaha, approximately 6,000 others participated by gathering at more than 200 local soil health forums nationwide, where this recording was broadcasted live.

 

Also available online are presentations from breakout sessions and 10 short videos of innovative farmers describing their use of cover crops.

 

Conference organizers are developing a formal list of recommended actions to increase cover crop adoption based on discussions at the conference and local forums. To see it when it becomes available, keep an eye on www.sare.org/covercropsconference or join SARE’s mailing list.

 

The conference recording features a discussion of how cover crops can improve soil health and the major barriers to their increased adoption, and was led by Buffett and fellow panelists Jason Weller, chief of the USDA Natural Resources Conservation Service, and Ray Gaesser, Iowa farmer and American Soybean Association president. Following them is a panel of farmers who are pioneers in the use of cover crops, no-till and other soil management practices.

 

Conference speakers addressed a wide range of ongoing challenges to cover crop adoption, including the need for more specialized seeding equipment, more advocacy by farmer leaders, more research on their economic benefits, and changes to insurance and conservation programs that better encourage their use.

Kura Clover – The Perennial Cover Crop

Kura Clover is an interesting option for cover cropping no-till corn producers. Why? Because Kura Clover forms a “living mulch.”

I have been working with Dr. Ken Albrecht from the University of Wisconsin-Madison on Kura Clover since the summer of 2000.  During that summer as I traveled through eastern Iowa and NW Illinois I envisioned that before 2005 all of that region would have Kura Clover on it!

That never happened. But I am still very excited about Kura Clover as a feed source and cover crop.

For Kura Clover to be best utilized on your farm you really need to graze it the first two years and periodically thereafter.  Cattle milked similarly on this mixture as what they did on alfalfa!
For Kura Clover to be best utilized on your farm you really need to graze it the first two years and periodically thereafter. Cattle milked similarly on this mixture as what they did on eating alfalfa haylage!

What’s so great about Kura clover?

Kura clover:

  • Produces high yields with little additional nitrogen
  • Fixes gobs of nitrogen
  • Forms a “living mulch”
  • Survives forever – stands last 30+ years
  • Makes livestock producers/row crop farmers smile
  • Provides diverse options in the field
  • Saves cover croppers money – a one time investment in seed
  • Controls erosion 
  • Is easy to work with in corn production

Why hasn’t Kura clover taken over the cover crop/forage world?

  • It establishes slowly.
  • It requires livestock (cattle or sheep) to be a part of the program for optimal benefit.
  • You cannot plant corn into Kura Clover every year.
  • You cannot plant soybeans into Kura Clover.
  • It must be inoculated with a special inoculant for it to establish/thrive.
  • It costs a lot in establishment year.
  • There are few producers of Kura clover seed – the biggest is CISCO Seeds.

Is it Ever Too Early to Plant Cover Crops?

Is it ever too early plant cover crops?  YES.

As many of you have figured out, I sell seed for a living.  I also have been a farmer or involved on the farm since I was a little boy.

But first and foremost I am an agronomist.

The temptation of a seed salesman is to recommend planting a cover crop either too early or too late – and then somehow justify it. However, as an agronomist and a former farmer, I simply cannot do that. I also want to be able to look at myself in the mirror without guilt.

Cover crops have to work for the farmer, not the seed salesman.  There are several fantastic seedsmen out there and I do not want to disparage that fine profession.  I feed my family by being a seedsman and marketing seed. Most seedsmen are a trusted source of information and quality seed.

Questions I Get A Lot

The planting date question comes up a lot. For example:

  • How soon can a farmer plant cover crops after wheat has been harvested?
  • Can a farmer plant clovers into corn at “the last cultivation?” (even though only a few farmers still cultivate).
  • When is it too early to plant radishes?
  • When is it too late to plant radishes?

Money has not always been good in agriculture and I doubt that this current boom will last forever (it never did before).  So I want to give answers based on sound agronomic practices that will work 90% of the time.

Question: Can you plant crimson clover at “lay-by”?

Yes you can.  My granddad did that practice back in the 1950’s.  Of course he planted in 38″ rows with 16-18,000 plants per acre.  He did not use herbicides but he did cultivate.

However, how many of us farm like my granddad did?  A few of you might –  with good reason to do so (specialty corn or organic production).  But, can it work with modern herbicides and plant populations pushing 35,000 plants per acre?  Maybe, but not consistently – and probably not.

I think I tried to say “no” but I’m aware that some farmers have done it.  But, can we do a practice if it is not going to work 90+% of the time?  Not on a large scale.  Can we afford to try it on a few acres?  Maybe.

Here is a northeast Indiana farmer’s testimony of his success spreading crimson clover into his growing corn at sidedress time.  I am sharing this exactly as it was sent to me – trusting that it is accurate. I do not know the farmer who submitted the testimony.

I broadcast 10 lbs/acre of crimson clover at sidedress time this year. I seeded it on 6/6. We got essentially no rain from the first week of May until the last week of July. I figured the clover wouldn’t grow, but it laid there until we got rain and by harvest we had a nice stand. I’m not sure how this would work in a ‘normal’ year, but it sure worked good this year. I left some check strips and the clover didn’t affect the yield.   The seeder was just an old 12V spinner seeder I clamped onto our N toolbar. I’m attaching pictures of it and the clover stand. 

Photos provided are below.

My Observations

My guess is that this farmer used only glyphosate and no residual herbicide.  It was also terribly dry this summer and this seeding would have been more like a “dormant seeding”.

This was not at all typical for an Indiana summer. It was the driest July on record and June and August were also very dry.  Note how short the corn is in the photo with the corn head.  There was a lot of corn 3-5′ tall this year in Indiana.  I’d guess that a 5 foot height would cover the corn height in this field.  If the crimson would have been planted in a “normal” year I would be surprised if he would have had success like this.  But, boy, it sure is a beautiful stand in these photos!

If you try this practice, just experiment with a few acres to see what works on your farm.

Note how short the corn is in the photo. Contrary to the belief of Illinois and Iowa farmers, this is not typical for NW Indiana corn! Most likely the rains that came in August were adequate to germinate the clover and there was plenty of sunlight getting to the ground so the seedlings had heat, moisture, and sunlight. What a beautiful cover crop!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Here is a beautiful stand of crimson clover between rows of harvested corn! Unfortunately the lack of corn fodder shows that the corn was under severe stress in 2012. While achieving a nice cover crop is important, I would prefer 200+ bushels/acre corn and a less advanced stand of clover at harvest time.

Question: Can you plant radishes right after wheat harvest?

No.

Even if you use an excellent radish,  it will bolt.  I don’t care which radish you use – it WILL BOLT if you plant it too early in the summer.

Bolting means that it will try to produce seed.  Generally a radish that bolts has a smaller and shorter tuber and most of the plant energy goes to seed production instead of root tuber production. If you wait until early August and use the proper radish you will see very little if any bolting.

I have been in several fields this fall that had no plants bolted.  I have also seen many fields that had a high percentage of plants that bolted.  Some claim that the exceptionally high soil temperatures in the summer of 2012 caused the August planted radishes to bolt.  That may be the case.  One thing I know for certain, if a radish is planted in July, it almost always bolts and can produce viable seed in the fall – and that could create potential problem for years to come.

Dave’s Best Advice

Wait until August to plant your cover crop radishes.  Use the few weeks between wheat harvest and planting cover crops to clean up weeds that were in the wheat field and also control volunteer wheat.  Patience is a great virtue.  It is important that you see an excellent return on your investments that we make in cover crop seed and seeding cost.  Our goal should not be “to be done first” but rather to have the best cover crop and healthiest soil.

I hate seeing fields like this as I know there was potential for seed to be produced and dropped to the soil possibly creating some issues in future years. Was this field planted too early or was the wrong radish planted? I do not know but I do know that farmers should chose wisely on planting time and what radish to plant.  Thankfully not every plant bolted so there are still plenty of plants “doing the radish thing” in the soil very well.

Cover Crops Enhance Water Infiltration/Percolation

In late September of 2011 I was walking in our family corn field in central Indiana–in the pouring rain. Following the wettest spring in the eastern corn belt in 100 years we had a summertime drought that saw less than 2 inches in July and August combined. In that same time period we had 32 days above 90 degrees.

We just had 3 inches of rain yet my soil was dry at 1/2 inch in this area that had been tilled wet in the spring.

On this September day we were having rain…3 inches worth of glorious rain! I threw on my rain coat and Tingley boots, grabbed my shovel and went into the corn field where our cover crop plots had been planted in the fall of 2010 and killed in May 2011. As I walked through the field I noticed that where the soil had been tilled (see previous blog post) I was seeing dry soil underneath my boot track! Now catch the scene here…no rain for much of 60+ straight days…now a 3″ rain and virtually none of the moisture getting into the soil! Literally I had less than 1/2″ of the soil depth that was moist! Dry footprints followed me all the way to the end of the field. I was not happy.

When I reached the area where the cover crop test plot was (that area was not tilled this spring) I dug into the check area that was no-tilled yet did not have a cover crop. In that area I dug into the soil and I found moisture 2 1/2-3 inches deep. This area was now no-tilled for 23 straight years. That made me feel better.

Water was standing (or running off) of the soil that was tilled wet in the spring of 2011. There was very little infiltration from a 3 inch rain

 

In this photo we see infiltration at 2 1/2 - 3 inches deep. This soil has been no-tilled for 23 straight years.

 

Then I dug in the area that had been no-tilled for 23 straight years and had a cover crop the previous winter. I was very pleased when I dug in the areas where we previously had annual ryegrass and cereal rye and found moisture had filtered (penetrated) in 7 (seven) inches deep!

Water infiltrated 7 inches deep where we had corn no-tilled into cover crop rye.

 

 

 

This section of the field had a cereal rye cover crop in 2010-11 and was no-tilled. Note the lack of water standing on top of the soil! Where did the water go? Into the soil!

 

Watch these videos on what I found when digging for earthworms in this sections with cover crops and no-till and where there was tillage without a cover crop. I believe we have an additional answer to why I had so much better infiltration where I had the cover crops..earthworms and roots!

This "rogue" radish provided information that we had a compaction zone at about 3 inches deep in our no-till field; thus reducing water infiltration where we had no cover crop.

Yet, I wondered, why did the moisture stop at 2 1/2-3″ in the no-till plots? I found the answer from a rogue radish. We had a few radishes that came up in the field that had been planted in the fall of 2010 (the fall of 2010 was so dry that many of the radishes did not come up until very late…or not until spring, or in a few cases until mid-summer).  As I previously wrote, Radish does have some hard seed.  I dug around one of the radishes and found a constriction in the radish at 2 1/2-3″ deep! Even after 23 years of no-till I still had a compaction problem! I believe that is one reason why cover crops help producers to transition from conventional tillage to no-till…cover crops penetrate through compaction layers.

Planting cover crop radishes with wheat? How do you plant them?

Planting Cover Crop Radishes with Wheat – A Growing Practice

Cover crop radishes planted with wheat at seeding time?

Last year I posted about how farmers in NW Ohio are seeing increases in wheat yields by 4-7  bu/acre by planting 2-4# of cover crop radishes in with their wheat seed. In the fall of 2010 there were more acres of wheat planted in Indiana, Ohio and lower Michigan than in many years before, and several of those acres had radishes planted with them with the hope of increasing yields.

Several test plots were planted as well. Unfortunately, the seed was planted into very dry soil and it did not rain until late October or early November so the radishes grew very little (if at all).  So the grand “radish seed planted in with the wheat seed” experiment was pretty much a flop in 2010 in the eastern Corn Belt.  However, I heard reports from Oklahoma and New York that claimed to see value in this practice.  By the way, 2# per acre is plenty.  4#/acre is too much seed.

How to Mix Cover Crop Radish Seed with Wheat Seed

As I have shared about this potential practice around the Midwest I often-times get the question, “How do I mix the radish seed with the wheat seed?”

Option 1

I first mention the “coffee can and paddle” approach of adding the seed.  As you fill the drill add some radishes and use a paddle (or even a tree limb) to stir it in.  With that approach I usually get a confused and almost angry look from producers that think I am mocking them (Seriously, I am not!).

Option 2

Since most farmers are more sophisticated than that I recommend adding the radish seed to the wheat seed at the seed house.  Then I get angry calls from the wheat seed suppliers about adding a “weed seed” into their bagging system!

Option 3

So I have concluded that the easiest way (and the way to recommend that will not get me in hot water) is to add the radish seed with the fertilizer that will be applied just before or after the wheat is planted.

Option 4

I’m open to suggestions.  If any of you do this differently will you please help out our fellow wheat producers?  Thanks!

These radishes are about the size we should expect to see when the season ends if planted with wheat. These radishes show the potential growth in just over 6 weeks since planting..

Farmer Report from Ohio – Planting into “Out of Control” Peas

The cover crop radishes varied in size with the amount of moisture in the field in the fall of 2010.

My good friend David from Mercer County, Ohio is a great cover crop advocate.  Over the past few years he and his father-in-law have begun planting cover crops after their wheat crop is harvested.  The first year he planted oats and cover crop radish and this past year they planted a mixture called N-Vest® Groundbreaker Mix (a mixture of Austrian winter peas and cover crop radishes).  The summer of 2010 set some records for being exceptionally dry.  Neither the peas nor radish grew the way anyone hoped for, but David did find radish roots around 20 inches deep.  The peas were less than spectacular but still acceptable for as dry as it was.

No-tilling corn into this mix of peas and wheat looked like an easy task in early May when this photograph was taken...but the rains kept coming!
This is not what was expected! Early June 2011 was wet and the peas were tall.

As I have reported in several previous posts, the weather in NW Ohio and the Eastern Corn Belt was the wettest in 120 plus years of keeping records.  The Austrian winter peas and volunteer wheat over-wintered.  In early May David was convinced that they would no-till directly into that “mix.”  But the rain came and came often! By early June the peas had grown quite a bit, like up to four feet tall…and that is what they no-tilled into.  Actually, David said it was the “most mellow soil” he planted into all spring.

Just a few days after planting David sent me the photos of a beautiful stand of corn where the peas had been over 4 feet tall.
Three weeks after planting the corn looked great and the cover crop was dead. This photo was taken June 21, 2011.

I joke that David was nearly written out of the family will when he started no-till planting his corn!  The neighbors were all watching but David persevered and kept planting…even though it was not as easy or as early as he hoped it would be.  A few days later David e-mailed me more photos…and then a week later more photos…

Exactly four weeks after planting and the corn looks remarkable.

So now the neighbors are wondering about this David “kid” that married into this operation.  Maybe he is not as foolish as they thought earlier in the spring!  Exactly four weeks after planting the corn was over “knee high by the 4th of July” and now the neighbors are asking what that cover crop was!

In mid-July, six weeks after planting and the weather has been HOT and dry...but according to David, the field "shows less stress" than conventionally tilled field that had no cover crops.

But the dry summer of 2010 was now being duplicated by another dry summer and the summer of 2011 has been much hotter than 2010.  So how has the no-till corn fared during these challenging conditions? Very well, actually.

There was less than 2" of rain in a very hot July and yet the field looks quite good considering the heat and dryness that it has experienced.

So will David plant cover crops again?  Yes!  In fact they are already in the ground and waiting for rain to emerge.  David has been very excited all the way through this process as he has been confident he is doing the right thing for his soil and the future of his farming operation.  Thanks to David for providing the photos and information to encourage all of us that cover crops are an exciting option that we should all consider.

Cover Crops underground…I was not disappointed, I was a bit surprised!

The Crimson clover had dense roots and we found a number of them at over 40″ deep.

At cover crop field days over the past few weeks many interesting aspects of cover crops were revealed. 

One reminder about cover crops; it is NOT what is above ground that is the best indicator of success. 

Please take a shovel with you when you evaluate cover crops and dig up some roots so you get the real story.

The radish tops were still quite eveident and some of the holes had yet to fill in completely. This field at Four L Farms had tremendous growth from the radishes and crimson clover last fall. The clover survived the winter beautifully.

First, we found deep roots from multiple species. While we expect to find deep roots from annual ryegrass we continue to be amazed at how deep other species are penetrating.  At Four L Farms near Francesville, IN we may have set a “world record” by finding 40+” deep roots from crimson clover.  We also found cover crop radish roots 40″ deep and annual ryegrass roots 54″ deep (as deep as the pit was dug).

When the pit walls collapsed I was quite surprised to see many root channels deep into the soil. I had never seen anything quite like this!

 

 

 

 

 

 

 

 

 

Next, we found earthworms in some fields and not in others. I think that this was a function of soil temperature and moisture.  (The soil temperature averaged 47 degrees at a 4″ depth).  However, I’m not sure that is correct.  We found a pretty good number of worms where we had more manure applied at Four L Farms on the annual ryegrass.  Typically crimson clover and radishes will have more earthworms around their roots than annual ryegrass…but this spring that was not entirely the case.  While we found worms around the radishes we found less than I expected around the crimson clover roots (again, no manure was applied in that field).

I always get a rush of excitement when we start digging pits so we can see what God did over the winter with our cover crops!

In the fields in Lake County, Indiana we were looking at fields that had never had cover crops in them before.  The producer is following corn and going to soybeans on most of the 900 acres he had flown on.  The mixture of cereal rye, annual ryegrass, and GroundHog Radish has looked good since last fall.  We were pleasantly surprised by what we saw there.  Nearly 20 producers came to the field day and saw root channels along the side walls of the pit.  Actually the pit collapsed and revealed an awesome display of root channels like I had never seen before.

I probably enjoy looking at cover crops way too much.  With the response from the producers looking at the root pits, I think most of them are getting excited too.

We’re digging root pits!

We are digging root pits to see what happened last fall and over the winter with cover crops.

On March 30 we were at Mike Werling’s farm south of Ft. Wayne, IN.  We held two cover crop field days at Mike’s over the summer.  We looked at the fields that had oats, radishes and peas in them (these were planted in 15″ rows).  The oats and radish roots were 34″ deep. Considering how exceptionally dry it was in the summer/fall of 2010, this is an impressive depth. 

The Crimson Clover looks great at Four L Farms in March 2011 at the Francesville, IN area. This was planted after corn silage in the fall of 2010.

On April 6 we will be in western Pulaski county Indiana at the Leman farms.  I posted about their farm last fall.  I hope we can dig 70+ inches deep (without filling the hole with water…or burying me in the process).  Last fall we aleady had roots 40 inches deep.  For info on the field day click Four L Farms Cover Crop Field Day April 2011.  Four L Farms plants their cover crops after corn silage in 15″ rows.  We’ll see crimson clover, annual ryegrass, and the vestiges of cover crop radishes. This is on a farm that applies dairy manure.

On April 7 we’re going to have another field day in Newton/Lake counties (Indiana).  We will be visiting Churchill Farms where they had nearly 900 acres aerial applied into standing corn last September (2010).  On this farm we will see annual ryegrass, winter cereal rye, and the vestiges of cover crop radishes.  For more information on this field day click Churchill Farms Cover Crop Field Day April 2011.

I hope you can all come!  These are great learning opportunities!  These events are co-sponsored by CISCO Seeds and local SWCD offices.
