Effects of an Early Season Frost


With temperatures dipping down to the freezing mark and lower Friday night to early Saturday, I thought it would be good to cover the potential effects of a frost on this 2020 crop. Both corn and soybeans should be able to handle a light version of a frost without too many ill effects. I consider a light frost to consist of temperatures ranging from 30-32 degrees for 1-2 hours. It is possible in this scenario for corn growth to be damaged but if the plant is small (v1-V2) it should make a full recovery due to the growing point still being below ground. Soybeans can usually handle a frost better than corn if both are emerged. A light frost could damage the first true leaves of a soybean but likely not damage the soybean cotyledons. Remember the cotyledons on a soybean plant serve as the growing point.

If temperatures stay in that 30-32 degree range for a prolonged period of time (3-4 hours or longer) or a hard freeze occurs, this is where the real threat could lie. With our ground being as wet as it is in central Illinois, I would not expect a hard freeze to affect anything that is not already emerged. However, dry soil will allow a freeze to go deeper. If you are in an area with dry soils, a prolonged hard freeze could be an issue if corn sprouts are within ½” of the surface. Soybeans in this scenario should fare much better. The soybean cotyledons and hypocotyl are much tougher and resilient than a young corn seedling. Any emerged corn during a hard freeze will likely be burnt to the ground but if the corn has not reached that v4 growth stage, I would suspect it to make a full recovery. Emerged soybeans during a hard freeze should survive if the cotyledons are not permanently damaged.

You will be able to tell if corn has been hit with a frost within the first 24 hours. Corn will turn dark green then will wilt and turn pale. Soybeans will start to show damage within the first 24-48 hours after a frost, but it will take up to five days before any real assessment of the crop can be made. If new growth in soybeans has not occurred within 7-10 days after a hard frost, then decisions will need to be made for replant. For any wheat crop, I would wait for 5 days then go split some stems and examine the seed heads for damage.

Our best friend for dealing with a frost would be for the winds to pick up and cloudy conditions to occur. If it stays clear and still, this is when a frost would likely hit. Hopefully, we can get through this weekend without too much damage and continue onward with the 2020 crop. Stay safe and stay healthy!

Planting 2020, Missouri – John Viertel

Well, here it is planting season 2020, and this is only my second blog of the year. With all that is going on in the world, I hope that you and your family(s) are well!

What has been going on the past few weeks? Some have had to stay home. For essential workers (agriculture, etc.), it has been business as usual, with social distinacing, face covering, gloves, and a whole lot of hand sanitizer. All that said, I have been getting products in place for the planting and spraying season, and corn planting here in Missouri has been going on the past two weeks. This week it is going full bore! If it stays dry and warm, beans are soon to follow.

I have a 16.5 foot ROGUE VT rented and it is running. This unique vertical tillage tool does a excellent job creating a seed bed for planting. It also can roll down a cereal rye cover crop (after it heads out) for planting soybeans into. Check out videos on YouTube, and blogs from last year. If you would like to try the ROGUE VT on your operation, get in touch with us asap at the contacts below.

If you are thinking about cutting costs going into this season, we advise not to try to cut costs in your herbicide program(s). Spray you weeds when they are small (4 inches or less) and use SOIL BOOST PLUS, SOIL BOOST EXTREME, and LANDOIL in you program. These spray adjuvants will help your herbicides work better! And they have a proven track record! If you want more information on these products, check out our web site: or contact us directly.

During my career in agriculture, there have been many challenges. Some have had a pretty severe impact on farmers and their operations. The Covid-19 pandemic is a challenge like we have never seen in our life times. All of us in agriculture need to stay strong and healthy, so we can continue to lead the world in food production. Also, to show, not only our county, but the whole world that we can continue to do our jobs efficiently and safely!

Have a safe and productive planting season! Stay well and do not forget to social distance. Funny concept when you are alone and in a tractor cab in the middle of 200-acre field!

Missouri Update – John Viertel

Rouge VT in the field


As we go into March, I am sure most of you will agree that it is wet across the Mid-West. We talked to producers from several states at the National Farm Machinery Show in Louisville, two weeks ago, and they agreed. I have also been talking to cattle producers here is Missouri. They tell me that with these conditions, their pastures are getting torn up and they will have to do some reseeding and other repairs when they dry out.

 So, if you are wondering how you are going to improve your pastures which have been tromped on all winter in these wet conditions, consider renovating with the ROGUE VT. Here are some things to consider:

  1. Top dressing and then running the ROGUE VT. The ROGUE will penetrate up to eight (8) inches, letting oxygen, manure, and the fertilizer go down into the root zone.
  2. Mix grass seed with the fertilizer, over seeding to get a improved stand in the pasture.
  3. Just run the ROGUE VT alone, to aerate, slice the grass roots (letting them spread out and thicken up), and the rolling baskets will break up and spread the cow manure.             

We have several ROGUE VT’S for sale or rental. One is equipped with an air seeder, so over seeding could be accomplished with the aeration pass.

This is the second year of wet conditions, so serious consideration should be taken to take care of your pastures. Contact us to get your machine lined up for your pasture improvement, or to get any questions you may have on this operation.

2019 is finally coming to an end! There were many challenges this year for a lot of us, but I am not going to dwell on those. Instead, let’s think about 2020!

 One of the comments which I have heard from many of you last summer and this fall has been, “Can I use Landoil® like a crop oil?” My answer: “Yes, you can. However, you will not get all of the advantages from it with the reduced rate.” I totally understand that saving dollars is on all our minds, and cutting the amount of Landoil in your spray program sounds pretty good, but you will not get:

  1. Uniform spray droplets
  2. Better spray coverage from the better spray pattern
  3. The best herbicide penetration that I have seen over the years
  4. Rain fast in twenty minutes or less—really improves some of the herbicide label times
  5. Kill weeds the first time and not having to re-spray—saves time and money

Using Landoil as we recommend gets you these benefits.  One custom applicator had to go back to a Liberty customer three (3) times last season. He had also sprayed fields for us with our program about the same time (only one application). He booked 275 gallons of Landoil in October and plans on getting more in season. The reason, he has seen how well our program is working and doesn’t like going back to re-spray.

As you are putting your plans together for 2020 and have question about our products for your herbicide program(s), get in contact with us. We can help kill your problem weeds the first time.

Follow-Up on Rogue VT Job in Missouri – John Viertel


As the snow melted on November 14, I was able to get these pictures from the field where the Rogue VT® worked 20 acres in the same field that was being worked with an Aerway/Remlinger harrow. Wheat was drilled behind both machines. The photo on the right was run with the Aerway, photo on left, the Rogue VT. Both machines were set at 10-degree tine angle, the most aggressive. The coulters on the Rogue VT, were set at the deepest setting, and were going in 3 to 4 inches in depth.

As I was talking to one of the operators, he was adamant that the ride behind the Rogue VT was so smooth, that he was able to increase his ground speed and the drill was still doing a great job! Another comment he made was that there would be less wear and tear on any planter or drill which followed the Rogue VT. We have said from the introduction of the Rogue VT that there would be a noticeable difference in the ride after running the Rogue VT versus the other machine.

Interested in what kind of a job the Rogue VT does in corn stalks? Look at the YouTube video that we posted on September 18. This implement can really do it all!

Harvest is still going on in Missouri, and the ground conditions are wet from Monday’s 1 to 3 inches of snow, if however, it does dry enough to do some more fall tillage, let us know. We can let you demo or rent a Rogue VT on your farm to see what true vertical tillage can do for your operation!
