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.

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.

Minerals for Healthy Soil & High-Quality, Top Yields

It’s a new century, and there is more knowledge about farming and the role of minerals, and there are more farmers paying attention to it. When it comes to farming, we know what the “base” is: putting all the pieces together including minerals, biology and soil structure — and using crop fertilizers that provide above and  beyond what the soil can dish out in terms of nutrients and biology.

A fall mixed cover the author grew after rye was harvested. He used the cover crop to capture nutrients in a biological form and to cycle nutrients to get more minerals into the following cash crop.

Even though there’s a lot of discussion about soil health, no-till and soil structure in farming right now, not enough attention is paid to minerals.

It seems like so much of agriculture is spending its time and money chasing magic biologicals, foliars or plant protection and not focusing on doing everything you can to feed your crop a balance of minerals and prevent the problems in the first place.

So what is your limiting factor or constraint that interferes with plant production and plant health? You need to understand that your farming practices have a lot of influence on plant health, and plants that are healthy protect themselves — just as you have an immune system that functions well if you are healthy. Reduce stress; eat a balanced diet with a balance of nutrients; eat a variety of foods that are clean without foreign compounds to fight and a good biological balance. If you get all that right do you need to take supplements?

It’s not farming the same way it was in grandpa’s day because there was a lot he didn’t know. He didn’t understand nutrients, soil health or soil fertility, and didn’t have the tools we have. He was stuck with a “plow.” If I asked you to do everything you could to get your soils healthy and mineralized, what would you do? Continue Reading →

Book of the Week: The Farm as Ecosystem

Editor’s note: This is an excerpt from Acres U.S.A. original book, The Farm as Ecosystem, written by Jerry Brunetti. Copyright 2014, softcover, 335 pages. Regular price: $30.00. SALE PRICE: $25.00.

An Invitation to Become a Legume

The Farm as Ecosystem, by Jerry Brunetti

 

Another exciting breakthrough in nitrogen-fixing bacteria originates out of the University of Nottingham’s Center for Crop Nitrogen Fixation. Professor Edward Cocking and colleagues found a specific strain of nitrogen-fixing bacteria in sugar cane that could intracellularly colonize all major crop plants. Remarkably, this development potentially allows all the cells within a plant to x atmospheric nitrogen! This technology, labeled “N-Fix,” is not a genetic modified/bioengineering technology, either. Rather, it is a seed inoculant, enabling plant cells to become nitrogen fixers, a hopeful boon to annual crop production, which uses wasteful and contaminating amounts of nitrogen. Commercialization of this non-GMO breakthrough is expected by 2015–2016.

In the same vein of investigating the “cellular wisdom” that exists among microbes and plants, researchers at the University of Missouri’s Bond Life Sciences Center, under the direction of professor Gary Stacey, discovered that, for reasons yet unclear, non-legumes have not yet made a “pact” with nitrogen-fixing rhizobia bacteria that allow legumes to convert nitrogen gas into plant food that can be used to build proteins.

Hands-on Agronomy, by Neal Kinsey and Charles Walters

No one used the term killer agriculture or knowledgeable mining when I was a youngster growing up on a farm in southeast Missouri. We raised corn, wheat, cotton, soybeans and a little hay. We also finished a few cattle. Now, a more mature sense of values brings the reality of our farming operation into focus. Sir Albert Howard identified the horns of the modern farming dilemma: partial and imbalanced fertilization, and toxic rescue chemistry.

Neither I nor my father heard or understood that dictum then, then being the 1950s and 1960s. All we knew was that the crops faltered—not occasionally, but year after year. My father had five sons and he concluded, “I hope you won’t even think about going into agriculture because it costs too much and I am not going to be able to help you get started. I hope you will go into business and be an accountant or something like that.”

Accordingly, I went to college with the intention of becoming an accountant. There was a problem with that. I couldn’t stand being inside four walls all the time. So I changed my direction while I was at the University of Missouri where I met William A. Albrecht, the legendary professor who contributed so much to what Acres U.S.A. calls eco-agriculture. Albrecht gave the Department of Soils its well-deserved reputation, but by the time I arrived, he had been retired—forcibly, I am told—in the wake of a great grant from a fossil fuel company. In any case, his classroom days were over, for which reason I was able to get more of his ear than might have been possible as classroom fare. He taught a private study course for Brookside Laboratory, and I decided to avail myself of this extra-curricular opportunity. He changed my entire way of thinking. Continue Reading →

Book of the Week: Ask the Plant

By Charles Walters and Esper K. Chandler

Editor’s Note: This is a combination of two smaller excerpts from Acres U.S.A. original book, Ask the Plant, written by Acres U.S.A. founder Charles Walters and Esper K. Chandler. Copyright 2010, softcover, 286 pages. $30.00 regularly priced. SALE PRICE $20.00.

It takes a cloudless night an adequate distance from the city’s light pollution to really appreciate the beautiful planet on which we live. Telescopes can take us well beyond the Milky Way, yet the unaided eye can find some planets in our solar system, and a little book learning can supply the intelligence that we have been here some 14 billion years, more or less.

Ask the Plant, by Charles Walters & Esper K. Chandler

This organism called Earth is no more than a speck in our planetary system, one that is swung on a gravitational string in a 300-million-mile orbit around a nebular sun. It wobbles slightly on its axis so that each hemisphere can be blessed with summer, winter, spring and fall.

Geologists tell us that planet Earth has many more mineral compounds than our sister planets, all of them fashioned from those elements that are blocked with such orderly symmetry on the Mendeleev chart.

How can these minerals have evolved from the same elements that service other planets? This evolution of inert minerals is aided and abetted by the life forms called microorganisms. Our microbial workers did not raise mountains from the deep. A fiery heartbeat from the center of the earth did that, striking land masses with tsunamis, sending water up or into a frigid air envelope, igniting ocean warming and great ice ages.
