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.

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!

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.
