Rolled Cereal Rye Update from Missouri – John Viertel

Harvest in the “Rolled” Cereal Rye Field

Notice the amount of residue still covering the ground

Clean field with just one herbicide and Foliar Opp® application


 Rolled Cereal Rye Update from Missouri

Last week we started the soybean harvest in the field that was planted into the rolled cereal rye this past June. If you go back and look at my blogs following this field, you can get a sense of what we did.

To sum up the year for this field, here are my observations:

  • Rolling he cereal rye with the Rogue VT®, killed the cover crop without a “burn-down” herbicide application               
  • With the tines run at 2.5 degrees, there was some loose soil under the “mulch” for better slot closure
  • Early weed suppression was excellent
  • Only one post herbicide application necessary
  • The “soil armor” helped keep the soil cooler during the hot weather, and protected the soil during high rainfall events we had this growing season. No erosion!

Contact us if you would like more information on “rolling down” cover crops, or other applications for the Rogue VT.

Harvest Update from Missouri

Corn harvest has been going on for several weeks now, and we have heard of some pretty average yields, along with some pretty good yields. Soybean harvest is getting started, but the rain that we had last week has slowed that down. I did see some combines rolling in beans yesterday north of Mexico. With nice weather predicted for this week, there will be a lot of harvest going on.

If you look back to blogs from April 29 and June 1, you will see that I was following the field that we no tilled corn into burned down cereal rye. We used 9-18-9-1 as the base starter, then added zinc, then Sugar E-Boost®, and then Max27-SRN®. There was 140 units of nitrogen applied pre-plant. Here are the results of the comparison plot that we planted in this field.

No Starter:                                          174.2 bpa

Starter Program:                              195.9 bpa

Starter Program + Max 72:            188.4 bpa

No Starter:                                          159.6 bpa

This is a 25 bushel yield increase where a good starter fertilizer program was utilized!

The average of the moistures was 14.4% with the starter and 15.1% without starter. Almost a full point drier.

The overall field average of the thirty-acre field was 156 bushels per acre across the scales. This field suffered the same problems that are across the area this season – drowned out areas in the terrace channels, thin stands on the flat ground that could not drain as well, and in this field, extensive deer damage on the outside twelve rows.

With conditions this spring, and knowing the history of this field, we were pleased with the overall outcome.

Nutrient Recycle Program – John Viertel

SOIL Service, Inc. logo


I have been catching up on my emails this week and I am wondering if everybody gets as many promotions for different things as I do. The one that caught my attention this morning was about a product that will break down the residue after harvest. Interesting to me, because we have been promoting, testing, and selling a lot of our Nutrient Recycling Program for the entire time that I have been with Soil Service. Even use it on our farm, especially on the field which we call “The Soil Health Study”.

What we have observed in this field (which I have written about in previous blogs) is better soil tilth, better water infiltration, less fertilizer used, less plant diseases, better yields, and an increase in Organic Matter.

What else can this program do for your operation!

First, when sprayed on you corn residue, with some 32% or 12-0-0-26, it will help speed the decomposition of that residue, and release nutrients back to the soil.

Second, that residue will be easier to manage next spring, especially if no tilling into it.

Third, residue (corn stalks) that have had all winter to break down after application, will not be as abusive to tractor and implement tires.

If planning a cover crop after harvest, and using a vertical tillage tool like our Rogue VT® or Aerway®, getting that little bit of soil on the residue after being treated, will speed up the decomposition, and the cover crop will sequester the nutrients to be released for the next crop.

If you are considering adding a “biological program” to your operation, contact us. We have had hands on with our program and have data to back up what we have seen.

Soil Temps in Soybeans – John Viertel

On Saturday, July 20, 2019, I put my Soil Thermometer in the pickup, and I was on a mission to check the soil temps in a couple fields of no till soybeans. First, this at 11 a.m. and I took the readings at a depth of about 3.5 to 4 inches. The air temperature on my truck was 90 degrees. This was a field of beans did not have a cover crop. The picture on the left, showing a temp of 80 degrees, was bare ground in a sprayer track. The picture on the right at 72 degrees, was in the middle of the 15-inch rows, under the canopy. Notice how well shaded the ground is. Plant height, just over knee high.

I then went to the field that we had rolled down the cereal rye and then no tilled the soybeans. Temperature readings were again 3.5 to 4 inches. The air temp had gone to 91 degrees on the truck. I was really expecting lower temperatures, but they were very similar. In the sprayer track, 79 degrees. Between the 15-inch rows, 75 degrees. Bean height, just above my knees, but the canopy was not shading the middles as well. Found out the two fields had been planted to different varieties of soybeans. The ones in the rolled rye did not close the canopy as quickly as the no till field.

What did I take away from this? Because the optimum soil temperature for active metabolism in most plants’ root zones is 64 degrees, striving to keep the soil temperature down is vital to having a plant that is not stressed, is able to take up moisture and nutrients more efficiently. Both the straw mulch from the rolled cereal rye and shade from the closed canopy help keep the soil cooler at the depth the temperatures were taken. The straw mulch will do the job until shading from canopy can take over.  I think I will pick a hot day this month (August) and do this again.

If you remember, that was the week that we had some very hot, humid conditions in Central Missouri. The Sunday night and early Monday morning following me being at those fields, they received about 2.5 inches of rain. Very welcomed!

Rolled Cereal Rye Field on 7/16/19 – John Viertel

Rolled Cereal Rye field on July 16, 2019

This is a general picture of the Rolled Cereal Rye field that we rolled and planted on June 4. There were no herbicides applied before or after planting. We depended on the mat of residue to help hold down the weeds until it was sprayed on July 5, 2019. This field has a history of heavy foxtail pressure because of hay brought in from Texas during an extreme drought in the early 1950s. Note the excellent job our herbicide program has done. Don’t think there will have to be another herbicide application to this field.

Here is that program (all per acre amounts): 24 oz. SOIL BOOST PLUS®, 32 oz. Landoil®, 32 oz. Max72-SRN®, 16 oz. Sugar E-Boost®, 2 gallons Foliar Opp® for legumes, 36 oz. Liberty, 10 oz. Volunteer, 2.6 oz. Hero.

Here is what the mat of rolled cereal rye looks like on July 16.

Did not have my soil thermometer with me last Tuesday, but I am going to put it in my truck, so the next time I get by this field I can get a soil temp in this field under that mat. Then get a reading in just a no till field. The last time I did that was several years ago comparing the temperature under the straw mulch vs. in bare soil in a minimum till field. The difference was significant then. Will be interesting to see if there are the same results this year. Check back to see the results.
