Soil Balancing: Worth Another Look — The Ohio State University Soil Balancing Team

Farmers make multiple management decisions daily — decisions driven by questions and input. Helpful input can come from many sources, guiding what to choose or avoid. Most university-led research has placed soil balancing on the “avoid” list. Still, it’s practiced by many farmers who report improved soil tilth, better crop yields and quality, and greater ease in managing weeds as the ‘balance’ of their soils improves.

At least one team of university researchers remains curious, wanting another look at soil balancing. Their work is beginning to reveal that farmers and researchers think, talk about, experiment with, and understand soil balancing differently. If those differences could be bridged, what new questions and helpful input might researchers and farmers find by working together?

The Science Behind Soil Balancing: Basic Cation Saturation Ratio

Soils vary in their nutrient content, but also in their ability to hold nutrients. A soil’s ability to hold nutrients is measured by its cation exchange capacity (or CEC). Generally, a soil high in clay content will have a higher CEC, but organic matter also increases CEC. Soils with a high CEC hold more nutrients and thus, can release more than soils low in CEC.

Organic No-Till Farming by Jeff Moyer

It is the hope and dream of many organic farmers to limit tillage, increase soil organic matter, save money, and improve soil structure on their farms. Organic no-till can fulfill all these goals.

Many organic farmers are accused of overtilling the soil. Tillage is used for pre-plant soil preparation, as a means of managing weeds, and as a method of incorporating fertilizers, crop residue, and soil amendments. Now, armed with new technologies and tools based on sound biological principles, organic producers can begin to reduce or even eliminate tillage from their system.

Organic no-till is both a technique and a tool to achieve farmer’s objectives of reducing tillage and improving soil organic matter. It is also a whole farm system. While there are many ways the system can be implemented, in its simplest form organic no-till includes the following elements:

  • annual or winter annual cover crops that are planted in the fall,
  • overwintered until mature in the spring, and then
  • killed with a special tool called a roller/crimper.

After the death of the cover crop, cash crops can be planted into the residue with a no-till planter, drill or transplanter. Whether you grow agronomic or horticultural crops, this system can work on your farm, and we’ll show you how to get started with this exciting new technology. Continue Reading →

True Soil Health: Create the Capacity to Function Without Intervention

My philosophy is that whatever you do on your farm should improve soil health. But how do you know what that is? The USDA defines soil health as, “The continued capacity of soil to function as a vital living ecosystem that sustains plants, animals and humans.” I would add to that definition and say that soil health isn’t just the capacity to function, it’s the capacity of soils to function without intervention.

The same field pictured below, three months later. This is the result of managing the field to promote healthy soil life and maximize biological nutrient cycling: a beautiful organic seed corn crop, just after detasseling.

What counts as “intervention?” Does intervention mean biotechnology, insecticides, fungicides and tillage? Is fertilizer an intervention? Do these interventions make your farm better for future years? I believe money spent on interventions needs to be shifted to inputs that yield soil health.

Appropriate intervention when absolutely needed is wise, but the goal is minimum intervention — in other words do everything you can to get the soils healthy and mineralized. Mineralize your soils using exchangeable nutrient sources that come from the carbon biological system. You have to create an ideal home for soil life and feed them in order to build soil health.

Remove the negatives, which include monoculture crops and excessive tillage. Reduce the use of other possible negatives added through harsh soluble fertilizers and excessive nitrogen, not to mention chemicals and biotechnology.

Farming for soil health means treating your farm like a system. For years we have been promoting the “rules” of biological farming (Six Principles of Biological Farming). Following these rules will lead to healthy soils that produce good yields. The soil health guidelines you now see published in many places focus on minimum disturbance with an emphasis on no-till. In my opinion not all soils are capable of being farmed no-till. Continue Reading →

Book of the Week: Biodynamic Pasture Management

Editor’s Note: This is an excerpt from an Acres U.S.A. book, Biodynamic Pasture Management, by Peter Bacchus. Copyright 2013, softcover, 160 pages. Regular price: $20.00.

Biodynamic Pasture Management by Peter Bacchus

To grow healthy plants and animals and high-quality food products, you need fertile soil. Soil fertility in turn is related to the growth and reproduction of soil organisms and to the plants that grow in the soil. In due process this affects the health, well-being and fertility of the animals and humans who live as a result of the plants that grow in the soil.

We often do not recognize that soil fertility depends on the carbon cycle, which starts with photosynthesis in plant leaves and the absorption of light and carbon and other elements from the air into the plant. The carbon taken in from the air by plants and transformed into sugars is the basis of the carbon cycle, which maintains life in the soil by providing food for soil organisms.

Gabe Brown on Building Resiliency through Soil Health

Farmer, Author Gabe Brown Discusses Soil Health & Diversity

Gabe Brown is one of the great bridge builders in farming. No matter which corner of agriculture you come from, or even if you don’t work in agriculture, Brown’s talks about how regenerative farming can restore our ravaged soils to vitality make sense. Moreover, he presents it with a plainspoken, pragmatic aplomb that captivates and never alienates, instead drawing listeners into the pleasure and excitement he gets from trying out new ideas. He explains techniques with a clarity that eludes many professional educators, and when the moment requires he can drive straight to the core of an issue with one stroke.

At an Acres U.S.A. conference some years ago, an audience member said it all sounded great, but asked why he should put in the extra work. Brown simply asked him if he cared about his grandchildren. People who come away from a Gabe Brown talk unsatisfied are rare as hen’s teeth.

Now, after many years of explaining his soil-building wizardry in person, Brown somehow found time to write a book, Dirt to Soil that tells his story and explains what he does and why it works. The book includes farming practices, a philosophy of nature and the story of how Brown and his family survived several years of natural disasters in the mid-1990s, an ordeal that proved pivotal. We last interviewed Brown in our October 2013 issue. We reached out to him for another talk five years later at his farm in North Dakota.

Gabe Brown: From Dirt to Soil

ACRES U.S.A. How did people such as Ray Archuleta, Dr. Kris Nichols, Dr. Christine Jones and others impact your effort to reinvent your whole way of working?

GABE BROWN. In my book, Dirt to Soil, I tried to tell the story in chronological order as to the people I met along the way and how they influenced me. I learned bits and pieces from many individuals, organizations and Nature herself, and it was up to me to take that information and apply it on my ranch. I wanted to show other producers that you’re not alone. You can glean information from many places, and it’s up to you to take that information and apply it as best you can in the stewardship of your own operation. Continue Reading →
