This spring (2017) SDSU Extension’s Anthony Bly and farmer, or shall we say “citizen scientist,” Al Miron got together to look at the influence of tillage, cover crops and manure on infiltration in a number of fields in Minnehaha County, SD. They compared soils in two long term (9 year) no-till fields, two conventionally tilled fields that had not been tilled for a year and one field that was deep tilled in the fall and then again tilled with a field cultivator in the spring. Al and Anthony did 4 repetitions at each site and came up with some interesting results as concerns the effect of cover crops and tillage. The “aha” moment experienced by the grower who loaned the team some tilled land to do the study on is important as his paradigm was “more tillage = less infiltration”. As this farmer saw the results, especially of the 5th (double-tilled) field, he was sold on the idea pretty quickly!
In this video, we recap the last 11 videos on our Merit or Myth Series that deal with residue and tillage. We sum up the information provided by our farmers and researchers, from West River to East River of South Dakota. As we consider the statement: “Farming without tillage and with surface residue is not only possible, it works!” we have to ask “Merit or Myth?”. It’s up to the viewer to decide.
This is the third part of a three part series in Dr. Anderson’s 10-minute talk on his spiral of regeneration.
Dr. Randy Anderson, Research Agronomist with the USDA-ARS in Brookings, SD, shares with us his spiral of soil regeneration. The concept of the spiral had its genesis in Dr. Anderson’s work in no-till where he observed a number of interactive biological effects at work. In this third video, Dr. Anderson provides a real-life example of two winter wheat scenarios based on tillage and crop rotation. It’s often that the farmer’s eye test is all that needs to be done to see where the advantage is, no degree in agronomy required! We hope this and the next two videos in the series give you a much better grasp of what happens when you begin to disturb your soils less!
Picture this: A proactive community of open-minded producers joining forces for the greater good. With all of them together, they work to increase yields and soil health, and gain a better understanding of their livelihoods.
If such a community existed, would you be interested? It may seem “pie in the sky”, but one state down, that’s exactly what’s going on.
COMMUNITY FARMING: SOIL HEALTH AROUND THE DINNER TABLE
For the last several years, an 8-member group of Nebraskan producers has gathered in the pursuit of shared knowledge. In that time, the positive effects of the union have been undeniable. Nobody knows this better than group member and Palmyra, Nebraska native Mike McDonald.
“One person in the group raised 6,000 bushels of cereal rye,” said McDonald. “Together, we cleaned it and, in a cost-efficient manner, were able to increase the drilling rates.”
As McDonald can attest, this is just the tip of the iceberg. What separates this group from your average producer get together is that they don’t stop at surface-level issues. Just like the roots of their crops, they always dig just a little deeper. One of the more popular topics of discussion? Cover crops. More specifically, livestock and how it relates to the practice.
PUTTING SOIL HEALTH TO THE TEST
It’s pretty obvious that high intensity paddock grazing can be a bit labor intensive, so to include such a practice in one’s operation, you’d have to thoroughly believe in its efficacy. Mike McDonald and members of his group have seen enough of the benefits of the practice to incorporate it despite the concerns. In fact, McDonald believes in it so thoroughly that he loaned 40 head of livestock from a fellow group member for a 20-acre site.
So what were these benefits?
According to McDonald and his group: increased soil fungi and other microbes (these are the “good guy” microbes that Dr. Elaine Inhgam talks about), decreased herbicide usage, and increased overall pool of organic nutrients (yes, nutrient pools can be organic as well as inorganic). Or look at it this way: increased efficiency and effectiveness leads to increased sustainability.
Of course, paddock grazing isn’t the only value-added practice that the 8-member group has tested and employed. McDonald also has up to 41 bee hives on his property that are responsible for increased production. After their discussions and research, the group also endorses cutting out virtually all fertilizer and herbicides as well as focusing on income diversity. Of course, with knowledge comes responsibility and the group acknowledges that. To incorporate livestock into an operation, one must be aware of cover crop maturity dates prior to planting, and proper grazing windows, but the results speak for themselves.
A UNITED FRONT
The idea of community learning shouldn’t be new to those who’ve followed along with us at Merit or Myth – uniting the South Dakota farming community has been a crucial discussion point for us. We’re excited to see such practices playing out in surrounding areas and confident that similar stories will start popping up across the Mt. Rushmore State soon.
In the meantime, keep your ear to the ground and listen for what your soil is telling you. There’s no telling what you’ll hear next!
Join the revolution,
Dr. Randy Anderson, Research Agronomist with the USDA-ARS in Brookings, SD, shares with us his spiral of soil regeneration. The concept of the spiral had its genesis in Dr. Anderson’s work in no-till where he observed a number of interactive biological effects at work. In this second video, Dr. Anderson walks us through the benefits to the farmer of regeneration that include better soil hydrology, better yields, better weed tolerance in crop plants and healthier plants. We hope this and the next two videos in the series give you a much better grasp of what happens when you begin to disturb your soils less!

Dick Nissen and his son Chris farm in Clay County, SD and encounter some of the typical east River conditions many farmers face especially in the spring (including residue). It turns out that Chris Nissen is a passionate soil health guy sometimes struggling to see why his neighbors spend as much as they do on inputs (including time for tillage) to raise the same crops and Chris and his dad do. Listen to Chris’s story and insights!
