Plants Beat Steel When It Comes To Reducing Soil Compaction

Plant Beat Subsoilers to reduce compactionAlan Sundermeier, a researcher at Ohio State University says, “You can’t solve your problems with steel.  Even with a subsoiler that may have minimal surface disturbance, it’s really not solving the problem. We’re seeing that soil structure can be better solved by using natural rooting systems through cover crops.”

In this video you’ll see the results of their experiments on compaction plots comparing subsoil steel vs. cover crops.  It’s just 4 and a half minutes, but it could change the way you look at soil compaction and what you can and should do about it.  Enjoy!  And stay tuned for additional videos from this great series.

I am the founder, editor and publisher of On Pasture, now retired. My career spanned 40 years of finding creative solutions to problems, and sharing ideas with people that encouraged them to work together and try new things. From figuring out how to teach livestock to eat weeds, to teaching range management to high schoolers, outdoor ed graduation camping trips with fifty 6th graders at a time, building firebreaks with a 130-goat herd, developing the signs and interpretation for the Storm King Fourteen Memorial trail, receiving the Conservation Service Award for my work building the 150-mile mountain bike trail from Grand Junction, Colorado to Moab, Utah...well, the list is long so I'll stop with, I've had a great time and I'm very grateful.


  1. Hi all,

    There’s a webinar coming up on this very topic. It looks like a good chance to learn more. Here are the details:

    Dec. 4, 2014: Introducing Radishes into the Organic Dairy Pasture

    Radishes can provide two benefits to the organic dairy pasture: 1) to extend the grazing season with a high energy feedstock, and 2) to provide “bio-drills” by utilizing the tap roots of these plants to address soil compaction. In this webinar, Fay Benson and Liz Burrichter will describe their on-farm research with brassicas, including no-till seeding Daikon Radish into grazing swards.

  2. Last year I had major compaction in a corn field where manure tankers entered and exited the field. There was a noticeable gap where the corn never grew. I intended to subsoil the field after the corn but for some reason or another it didn’t happen. In early September we planted a mixture of tillage radish, triticale and annual ryegrass. After grazing the mixture this spring we planted sorghum sudan grass. I could not see any compaction at the same spot where the corn had problems. I’m now a believer that soil compaction can be relieved by cover crops and that deep ripping isn’t necessary in most cases.

  3. Why not do both? A combination of crop/cover-crop AND subsoiling/aeration. Can you imagine what would happen then? The perfect root zone for the crop. Air, water infiltration and practically no resistance for deep root penetration and proliferation. I suggest taking a look.
    Why are we looking at conventional cropping systems anyway? Isn’t this primarily a grazing publication?
    I look forward to more of your unbiased information. Thank you.

    • Hi Eric,

      Thanks for writing. You raise two good questions: why not both steel and cover crop? and why are we covering cropping systems in On Pasture? To answer the second question first, we have readers who use both pasture and field crops on their farms and ranches.

      As to the question about steel + cover crops, farming is known for its very tight profit margins, and cover cropping has been shown to do the trick necessary (improve soil health) while potentially providing an additional feed source. That’s win-win in our book.
      We’ve scheduled additional articles on the topic in future issues of OP. We’re glad you like our unbiased information. Keep reading! Don’t forget to fill out our survey to help us keep going – free, easy, and you can get a bumper sticker:
