Cover Crops to the Rescue!

A Huge Problem

Brad, TJ, and Andrew inspecting on of Brads many cover crop fields that were planted in July 2013.on prevented planting acres.
Brad, TJ, and Andrew inspecting one of Brads many cover crop fields that were planted in July 2013 on prevented planting acres.

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.

This beautiful stand of cover crops was planted July 2, 2013 at Brad's dad's place not far from the hog barns.  If you sniff this photo real hard you can smell the hogs!

Cover Crops and Prevented Planting Guidelines

There are thousands upon Thousands of acres - mainly in the upper Midwest not planted in early June 2013.
There are thousands upon thousands of acres – mainly in the upper Midwest still not planted in early June 2013.

Over the past few weeks I have heard from countless farmers in Wisconsin, Minnesota, Illinois, Missouri, Michigan, and Iowa that are considering taking prevented planting on all or parts of their farms. Growers Edge just published an excellent piece Prevented Planting Guidelines. 

Also see my articles on Prevented Planting Row Crop Acres – Which Cover Crops Can Help? and Summer Annual Grasses for Cover Crops for Prevented Planting Acres that may also be helpful.

Prevented Planting Row Crop Acres – Which Cover Crops Can Help?

The following was originally posted on May 27, 2011 when the Eastern Corn Belt was suffering with severe flooding and wet conditions.  In 2013 the Upper Midwest – especially Iowa, Minnesota, and Wisconsin – is flooded and wet.  Many farmers are considering taking the crop insurance for prevented planting.  Even if it would stop raining – which does not appear will happen anytime soon – many farmers will not be in their fields for two weeks.  While locations are different, the recommendations below still apply.  Please keep the farmers in the Upper Midwest in your prayers; they need it!

For other options that might include growing cover crops for forages click here.

More rain tonight on already flooded fields create a tough situation for many Midwestern farmers.
More rain tonight on already flooded fields create a tough situation for many Midwestern farmers.

In 2010 there were wet spots in fields that were never planted,  so some ingenious farmers planted cover crops in those spots after they dried out.  Now in 2011 there are several entire fields that may not be planted to cash crops at all.  I have heard from two friends in Ohio that are working on plans to help northwest Ohio farmers know what to use on their prevented acres.

Maybe this is not an issue where you live.  I hope you never have to face a spring like this year in the Eastern Corn Belt, where many producers in Ohio, Indiana, Illinois, and Michigan are struggling to get their crops in the ground.  The forecast is for many more days of rain to finish out the month of May.

For wet spots in fields there are many good options like these cover crop radishes that were planted later in the season in a field of sweet corn.

For prevented planting the cover crops may not be harvested until after November 1st.

So what are the options for planting cover crops in the prevented planted fields?  Below I will list the options with a few of their benefits and also some disadvantages.

Oats

Advantages

  1. Provides erosion control
  2. Scavenges nitrogen
  3. Grows a deep and fibrous root mass
  4. Promotes mycorrhiza growth
  5. Quick to establish
  6. Relatively inexpensive
  7. Can be broadcast and lightly tilled in
  8. Can be added to other cover crops to add additional value
  9. Can spray with broadleaf herbicides if necessary to control weeds

Disadvantages

  1. While they provide cover and decent root growth they do not provide additional nitrogen to the soil (at the most it would be very minimal)
  2. Best to use seed oats vs. bin run oats for optimum value
  3. If planting wheat after oats there may be some “grass after grass” issues (I’m not confident this will be a problem and would welcome comments)

 

Field Peas or Austrian Winter Peas

Austrian Winter Peas and cover crop radishes were planted into prevented planting acres in Michigan in 2010. These peas were producing nitrogen for the 2011 crop while fields that were sprayed or tilled for weed control had no such benefit.

Advantages

  1. Can provide 60-120 # nitrogen/acre (excellent if following with wheat in the fall)
  2. Can be broadcast and lightly tilled in (1″ or deeper)
  3. Can be added to other cover crops to add additional value (add to oats)
  4. Can spray with broadleaf herbicides if necessary to control weeds

Disadvantages

  1. Slower to establish than oats
  2. More costly than straight oats
  3. Seed MUST be inoculated at the time of planting

 

Crimson Clover

Advantages

  1. Can produce up to 150# N/acre within 100 days (great option if following with fall planted wheat or Winter Barley)
  2. Fairly quick to establish
  3. Relatively inexpensive
  4. Can be broadcast and lightly tilled in (1/4-1/2 inch deep)
  5. Can be added to other cover crops to add additional value (add oats at 1 bu/acre)
  6. Can spray with broadleaf herbicides if necessary to control weeds (This article is for seed production in the northwestern part of the USA)

Disadvantages

  1. More costly than straight oats
  2. Slower to establish than straight oats
  3. Seed MUST be inoculated (it may be purchased pre-inoculated)

 

Cowpea

Advantages

  1. Can produce 60-150# nitrogen/acre
  2. Can be broadcast and lightly tilled in (1″ or deeper)
  3. Can be added to other cover crops to add additional value (add to oats)
  4. Can spray with broadleaf herbicides if necessary to control weeds

Disadvantages

  1. Cost and availability of seed
  2. Slower to establish than oats
  3. Seed MUST be inoculated

Other crops to consider: Berseem Clover, Fava Beans, and others.

Cover Crops Provide Improved Corn Yields in On-Farm Trial

All of what is reported below was accomplished after only one year of cover crops.  This work was inspired by a conversation Don and I had last winter with Dr. Eileen Kladivko from Purdue University.  As I say in cover crop meetings,

Don’t expect a miracle the first year – but look for one.

Over the exceptionally dry and super hot late-spring/summer months of 2012 my brother Don Robison collected “plant-health” related data on our corn field at Robison Farms near Greenwood, IN.  Don took data on the corn  from each area of the cover crop plot we planted last fall over the top of a soybean field as well in the “check area” (no cover crop area).

The data he took throughout the summer included plant chlorophyll readings, plant height, and compaction readings.  I presented some of the chlorophyll data on the CropLife Webinar and at several cover crop meetings this summer (and more is posted below).

On August 15th Don and I took hand harvested yield checks from each area and from the check area.   The data on the corn yield was almost identical to what we found with the chlorophyll data and compaction data. Where we had the healthier plants all season long (more “green-ness” and deeper roots) we had higher yields.

To figure yield we utilized this formula we found at a Purdue University agronomy website.

Each cover crop treatment out yielded the “no cover crop check”. The top three yielding plots also had the least compaction and highest chlorophyll readings through out the drought stricken summer.  The check plot yield was 105.24 bushels per acre.  The top yield estimate was 164.82 bushels per acre.

 

The area where the plot was had a 24″ water line was installed by the county in 2009; so it was intended to be a “rescue disturbed soil trial”.  The corn was not harvested directly over the water line but it was where the soil from the water line was mixed in with the top soil.  In 2011 the field was in Soybeans and yielded 48 bushels/acre.  In 2010 the field was corn and yielded 198 bushels/acre.  The whole field has been no-tilled for most of the past 20 years (there were some years with conventional tillage done – mainly in the early 90’s).  175 Units of N were applied (100 units (28%) with the chemical burn down application early season and 75 units side dressed (28%) in early May).

Rainfall from May 1 to July 31 was 2.24″ (with only 0.75 from May 1 to July 19).  There were 42 days over 90 degrees and 8 days over 100 degrees during that time.  All time record dry and heat was recorded in July, 2012 in the area.

Don took chlorophyll readings weekly (one week missed in July due to a family vacation).  He took 30 chlorophyll readings per plot per sampling date.  He also took multiple plant height readings each time as well.  He followed the manufacturers instructions on the chlorophyll readings and penetrometer tests.  Don spent a lot of time in this field so we could all have this data!  Thanks to The CISCO Companies for providing the seed, equipment, and Don’s labor to collect this data.

 

This chart shows the percentage above the no cover crop area (the “check”) compared to the different cover crop mixes. The two comparisons on the far right are from a soybean study we ran where we had cover crops two consecutive years compared to one year (more data and a post coming soon on this study).

Observations:

  • The plot areas that rated healthier (more green-ness and taller) yielded the best.
  • The plots areas where there was less compaction yielded the best
  • The plots with annual ryegrass did not fare as well as some others in this drought year – yet was still considerably above the check.
  • Not all plots with radish were “top” yielding – however two of the top three yielding plots had legumes plus radish.
  • Plots with legumes were generally healthier all season long and their yield reflected that.
  • I doubt that the whole field will average over 100 bushels/acre.  As with all hand yield tests they are estimates but I believe that the comparison is very accurate.
  • The Austrian Winter Peas, Crimson Clover, and Appin Turnips overwintered “beautifully” and were growing aggressively when sprayed at burndown.
  • There was a considerable amount of earthworm activity in the cover crop area but only a few earthworms were found in the “check” area. That is unfortunate because 2 acres were covered and 48 acres were not!
  • There were more corn roots in the plot areas we dug vs. the check area (watch for a new post coming on this soon).
  • There was more moisture in the soil where the cover crop plots were compared to the check area.
  • The soil structure was considerably better in each cover crop plot vs. the check area.
Don recorded over 180 chlorophyll readings in each cover crop plot and check plot over the summer.

 

The check plot had 175 units of nitrogen plus the whole field had been soybeans the previous year. While the annual ryegrass blend plot was above the check all season long it was not up to the desired level until after the July 19 rain event.

 

The plot with the Oats and Rye and Appin Turnips was impressive most of the spring and summer. It was at or above the desired rating until August. It was very impressive right after the July rain event and that is possibly why it had the second highest estimated yield. By the way, the turnips did live through the winter.
All season long I was convinced that the plot where the Austrian Winter Peas and Radish were was going to have the highest yield based on the data shown above (and plant height readings). It beat the second place entry by less than 1/2 bushel in the yield estimate.

Harvesting Cover Crops for Emergency Fall Forage

Need Feed?

Many producers across the Midwest and beyond have very poor corn. Grain and Silage yields will be significantly lower than normal in 2012.

Harvesting cover crops for emergency fall forage may be able to play a major role in lessening the impact of the 2012 drought disaster for livestock producers.  As I traveled from Indiana to eastern Iowa and through Wisconsin I saw dry ponds, cracked soil, nearly dead alfalfa, completely brown pastures, and an exceptionally poor corn crop.

I have received phone call after phone call from dairy and beef producers asking what cover crops they can use to provide food for their animals this fall and winter.  Below I have listed a variety of choices that may work well for producers needing feed (if we get rain).  By the way, these choices are also excellent cover crops.

Fall Forage Fast- Mechanically Harvested

Sudangrass or Sorghum X Sudangrass

BMR Sudangrass is a great choice for fall feed - IF you can get your hands on some this year.

Both of these would be choice 1-A and 1-B. However the producers in Texas have been experiencing drought for the past few years and seed supply is exceptionally tight.  Choose BMR varieties if you can find them.

Spring Oats/Spring Triticale

This photo was taken south of East Lansing, MI in April 2010 and shows Oats in the center with Cereal Rye to the left and Spring Triticale to the right.

This is not a “sexy” choice but it is a very good option.  Oats sown in July and August will out-produce all of the winter cereal grains if a fall harvest is desired.  I have worked with Ed Ballard from the University of Illinois and Gary Wilson from Ohio State University Extension for a number of years on summer seeding Oats and found great success almost every year.

Stan Smith from OSU Extension is a real believer in summer seeding oats as seen in this excellent article.  Seed the Oats at 2 bu/acre and fertilize with 50+ Units of N or manure equivalent.  Spring Triticale will behave very similarly to Oats when summer seeded.

Oats and Crimson Clover

From this photo of crimson clover, you can see the potential forage value planted with oats (note the field in the background).

I really like this mix because it will be higher quality than plain oats.  Plant the oats in the grain box and the crimson clover in the small seed box.  Plant the oats at 2 bu/acre and the crimson clover at 5-8#/acre.

Nathan Anderson of Cherokee, Iowa (NW Iowa) planted this mixture in 2011 and had very good success. While taking one cutting for hay and grazing 2 times in the fall/winter, he showed a profit of nearly $140/acre in beef production (weight gain) and hay produced.

Make sure that the crimson clover is inoculated and do not plant the crimson clover more than 1/2″ deep.

Oats and Cereal Rye (or Winter Triticale)

Oats (left) and Rye (right) planted in August show the value of Oats as a fall forage in this photo taken in October 2011 in NE Indiana.


Harvest the oats in the fall and the cereal rye in the spring.  I’d look at 2 bu/acre oats and 1 -1/2 bu/acre on the cereal winter rye or triticale.  Consider adding 5-8# of Crimson clover to this mix as well.

 

 

 

 

 

 

 

Oats (or Spring Triticale) and Peas (Forage or Austrian Winter Peas)

Austrian winter peas can produce A LOT of quality forage.

Plant a 50/50 mix of this combination for high quality fall forage.  Be sure to inoculate the peas.  Plant this mix 1 1/2 -2″ deep for best success.

 

 

Annual Ryegrass/Annual Ryegrass – Crimson Clover Mix or Italian Ryegrass

Annual ryegrass makes great fall and spring feed. It loves nitrogen, so apply plenty of manure. Add crimson clover to this, and WOW!

Annual Ryegrass or Italian Ryegrass will not produce the tonnage that the spring cereal grains will.  Ryegrass needs cooler temperatures, more moisture, and more fertility than the spring cereal grains need.  The main benefit is that you can get a very high quality forage…just not a lot of it unless you have the moisture, cooler temps, and higher fertility.  Maybe in the southern parts of the Midwest and further south this can be a good option.  Italian Ryegrass will not grow as aggressively in the fall as Annual Ryegrass will.

 

Spring or Winter Barley

Barley is a multipurpose cover crop that can be beneficial to hog, dairy, and beef producers.  It is a wonderful grain to use for feed and it is harvested for grain in June.  The haylage would be harvested in May with plenty of time to plant corn silage or Sudangrass.  Spring Barley planted in July/August will act like Oats and spring Triticale. Winter Barley will act more like cereal rye or winter Triticale.  Plant 2 bu/acre for grain production and 3 bu/acre for forage production.  Use less N than you would with Wheat or Ryegrass.

Spring or Winter Barley is also an option. Barley grain can be fed pretty similarly to corn and be harvested in June.

Cover Crop Root Pits Reveal Plenty

During the first week of April I was in several root pits in northwest Indiana and boy did we find plenty of interesting factoids! I was assisted by Eileen Kladivko from Purdue University on one day and Barry Fisher, Indiana NRCS State Agronomist, on another day.

What We Found in the Cover Crop Root Pits

We found several night crawlers and smaller worms as well in each pit we were in
  • Earthworms galore, especially where we had radishes and/or crimson clover. But the earthworms were plentiful in all cover crop species.
  • Earthworm channels 48″ deep in a field that had been long term no-till with one year of cover crop annual ryegrass/radish mix (planted after soybeans).
  • Roots from two different  crops in the same root zone/earthworm channel (soybeans and cover crop roots) over 30″ deep.
  • Earthworm eggs where radishes had decayed.
  • Soybean nodules 26″ deep on roots that went 44″ deep (long term no-till field – 10 years).
  • Annual ryegrass roots that were not as deep following corn as they were following soybeans (less N available for them to grow as vigorously).
  • Canola or oilseed rape in fields where bin run oats had been planted instead of seed oats.
  • Continued evidence of compaction. One year of cover crops does not eliminate all compaction issues (though roots from cover crops did penetrate through the compaction).
  • Radish and radish roots that were 34″ deep last fall were found at 40″ deep this spring (though dead).
  • Living radishes. Several radishes survived the Indiana winter (very mild winter), especially where they were protected by crimson clover and annual ryegrass.
  • 20 earthworm channels and 5 earthworms in an area 8″ by 8″ square at 6 inches deep (in a mixture of annual ryegrass, crimson clover, and cover crop radishes).
  • 700 acres of oats and radishes looking very different in the spring than it did in the fall!  (Click the links to see the different videos)

Miscellaneous Notes from the Cover Crop Root Pits

The farmer from our first cover crop root pit dig on April 4th reported that he saw less visible drought stress where they had long term no-till and cover crops, attributing the healthier plants to increased root depth.

We saw several fields of cereal rye after corn stalks being grazed by beef cattle.

Barry Fisher encouraged everyone to “expand your farm vertically.” In other words, don’t just keep buying/renting more land. Instead, put cover crop roots down deeper to create better land where you farm – and get more yield.

Be sure to control your annual ryegrass instead of waiting on the crimson clover to grow taller.  Much of the ryegrass was 10-12″ tall with the crimson clover at 6-8″ tall.

Farmers are becoming more creative with cover crop applications and types, and they are finding success – not surprising!

 

Other than the "extra goodies" from the VNS oats, this field was ready to plant without herbicide in the spring.
We saw several fields where cattle were grazing cereal rye planted into corn stalks.
Cereal rye in one row and crimson clover and Appin turnips in the other row (mixed together).

 

One of the joys of working with farmers is the excitement I see on their faces when they "get it" about soil health. There were several excited farmers again this spring.
We found several earthworm eggs around the decayed radish holes.
We found roots from soybeans and annual ryegrass in the same root zone/earthworm channel.

Grazing Cover Crops in the Winter

Over the past 9 years I have worked with Ed Ballard from the University of Illinois on grazing cattle over the winter.

During the first 4-5 years I was much more concerned about the “above ground” aspect of the cover crop and weight gain by the animals.

However, these past 4-5 years have shown me the dual benefit of this amazing plan.  The mix I use is 1-1/2 to 2 bushel per acre of oats, 1 bushel of winter rye and 5# of Appin Turnips.

This mix works well flown into standing corn or drilled right after the corn harvest.  I have attached a You Tube video to show the wonderful benefits cattle producers can get using this cover crop.

Oats…a wonderful and versatile cover crop

Oats and Radishes
Oats and Oilseed Radishes with hog manure. Planted after wheat. This makes for a great combination.
Oats and Oilseed Radish Mar 16 2010 - 4566 (4)
The Oats and Oilseed Radishes in the spring of the year. These photos are from the same field.

Oats are one of the more versatile cover crops as they can be planted various times of the season and used as an excellent cover and an excellent forage crop.  Oats work well alone, but especially well in mixes with oilseed radishes, turnips, Berseem and Crimson Clovers, and Austrian Winter Peas, etc…  Oats work well for erosion control and are very good nutrient scavengers.  Oats (and mixes with radishes or turnips) work very well for manure nutrient management.

Advantages of Oats

  • Scavenges N
  • Deep and fibrous root mass
  • Works well with aerial application
  • Excellent for forage
  • Winterkills
  • Oats work very well with other cover crops in mixes

Disadvantages of Oats

  • Bin run oats will have weed seed in them
  • Winterkills

Plant Oats at 1 ½- 2 bushels/acre for cover/grain; 3 bushels/acre for cover/baleage
