Book excerpt: Humusphere by Herwig Pommeresche

Herwig Pommeresche, a German-Norwegian explorer of soil life, graduate permaculture designer and graduate engineer, shares his lifetime of research into humus. Humusphere, translated into English for the first time, digs deep into a myriad of little-known research papers, comparing their findings with the usual conventional methods.

Herwig Pommeresche offers an ecologically oriented understanding as a check to the still prevalent chemical-technical agricultural system.

In the excerpt below, Pommeresche discusses the cycle of living material and its biological and chemical roots.

From Chapter One: Agrobiology and Agricultural Chemistry: Two Sides of the Same Coin

Whom Does Agriculture Serve?

I would like to pose an intentionally provocative question: Who should determine the future of agriculture and thus our food supply? Should it be the field of chemistry or the field of biology? Continue Reading →

Detecting and Understanding Stray Voltage

All stray voltage is unintentional and undesirable, yet it is extremely common. In fact, it would be rare to find a farm or home without it, usu­ally not in a good location. The main culprit, even though there are several variations of causation, is that with all standard 120 volt wiring we only have one hot wire, one neutral wire and a ground wire.

If the neutral wire is in­adequate or if there is a weak or failed connection, the electrical current ar­riving on the hot wire must return to the source in some manner, which means it will try to go through any and all other objects that will conduct electricity. This undesirable flow of electrons can be via the earth, metal buildings, metal stanchions, fences or other objects.

The motor on a center pivot irriga­tion tower had been experiencing a tiny short in the wiring recently on a Midwestern farm. It had been this way for several weeks, but it was still working, and as you know there’s never enough time to do everything on the farm. However, the sand filter on the irrigator was also full, and this function needed emptying. The farm­er was up on a metal ladder opening the overflowing trap to clean it out. It was safe, because all the pumps were switched off — except for what he did next, which was to instruct his wife to turn on the pump in order to flush the sand. It was a fatal mistake, as 480 volts surged through the system, instantly killing the farmer. Continue Reading →

Building the Microbial Bridge to Support Nutrient Availability

The root zone around plants, known as the rhizosphere, is an area of intense activity in the soil. It’s a lot like the snack stand at the state fair on a hot day. Everyone is crowding around trying to get to the cold drinks, funnel cakes and hot dogs. Snacks are being sold as quickly as the workers can make them. In return, the snack stand is bringing in a lot of cash.

Corn roots with lots of root exudates and soil sticking to the roots.

While the snack stand exchanges food for money, plant roots feed nearby microbes in exchange for plant nutrients. The roots put sugars down into the soil, creating an area of crowded, busy bacterial feeding in the rhizosphere, and exchange that microbial food for nutrients the plant needs but would otherwise have a hard time accessing.

We tend to think that plants photosynthesize entirely for their own metabolism, but in truth plants spend a good portion of their energy feeding soil life.

Plants fix sugars through photosynthesis, and while 55 to 75 percent of those sugars support plant growth, reproduction and defense from pests, the rest goes into the soil through the roots to feed the soil biology. This isn’t a waste of energy by the plants.

Those organisms living in the rhizosphere, primarily bacteria, not only make nutrients available to the plants — they also provide a protective layer against pests and diseases. It’s a win-win for the plants and the bacteria living in the rhizosphere. Continue Reading →

Tractor Time Episode 23: The 2018 Eco-Ag Preview Special

Hosted by Ryan Slabaugh

Good day and welcome to Tractor Time podcast brought to you by Acres U.S.A., the Voice of Eco-Agriculture. We are happy to be bringing you another episode, our 11th this year and 23rd overall, and I think we’re going to get in at least one more before the end of the year, so stay tuned.

It’s about that time. Starting Dec. 4, Acres U.S.A. is hitting the road — or getting on a plane, actually — and heading to Louisville, Kentucky, for our 43rd annual Eco-Ag Conference & Trade show. In the office, we’re at that hybrid stage of nervousness, confidence, anxiety and adrenaline, and our days are filled with all the little odd jobs – cutting badges, ordering bags, shipping off our bookstore – and we know a lot of our listeners who will be attending are doing the same. Getting ready for the week away.

Eco-Ag Conference & Trade Show logoSo we thought it’d be appropriate to preview a few of our upcoming speakers on the show today, and include some of our sponsors. We don’t do a lot of advertising or sponsored stuff on this. Plus, these aren’t your normal sponsorship messages. These are folks just like you – passionate about eco-agriculture and making a difference. And paying the bills, of course. Continue Reading →

Successful Crowdfunding for Agricultural Pursuits

With bank loans hard to come by, many farmers are looking for alterna­tives, and one of the new models is online crowdfunding, a form of Inter­net-based donations, loans and invest­ments. Many of the online platforms, such as Kickstarter and Indiegogo, attract large numbers of entrepreneurs looking for funding.

Barnraiser founder Eileen Gordon with Rob Keller of the Napa Bee Company.

According to Eileen Gordon, founder of Barnraiser, hers is the only crowdfunding platform devoted spe­cifically to funding the sustainable food movement “one farm or healthy food business at a time.”

Speaking at a recent EcoFarm con­ference, Gordon told attendees, “We’re trying to connect with the 40 or more million Americans who care about sustainability, health and wellness, yet they don’t often know how to affect change. There are still many parts of the country where consumers don’t have the opportunity to vote with their forks at the grocery stores by choosing sustainable foods.”

Gordon asserts that crowdfunding is rapidly changing the way we drive innovation, personal aspirations, new products and social change.

“No group is more deserving than those on the front lines of the food movement, leading us toward health and sustainability,” she said. “Barn­raiser is a place to meet and back the thousands of food and farming innovators and put better food on our collective table. When one farmer gets a new barn, the whole community gets better food.”

Gordon is also co-owner with her husband, Michael Chiarello, of Chiarello Family Vineyards in Napa Valley. About 12 years ago, she and Chiarello acquired a 100-year-old vine­yard in the Napa Valley and converted the land into a sustainable farm. It was an old historic farm that had been planted before prohibition and hadn’t been farmed in over a decade.

“In the process of taking this old farm and rejuvenating the land and converting it to sustainable farming, we met some fantastic people in the realms of organic and biodynamic farming. As we saw our property come back to life as a healthy ecosystem started to thrive, this was incredibly exciting to us.” Continue Reading →

Meet The Sioux Chef: Revitalizing Native Foodways

From the plains of the Midwest, a new and surprising trend in the world of healthy local food is gaining ground thanks to Sean Sherman, an Oglala Lakota Sioux and founder of The Sioux Chef, a nonprofit organization aiming to revive the traditional Native American diet through hands-on education and the use of indigenous ingredients.

Worlds of Flavors at the Culinary Institute of America-Greystone.

I first heard Sherman speak at the Missouri Organic Association conference where he was keynoting at the event’s locally produced organic dinner. He took the stage and held 600 people rapt with attention as he spoke with passion and wisdom about Native American history and their foodways and the need to rediscover the indigenous foods that nourished native peoples around the world for hundreds of thousands of years.

A Different Path

Sherman grew up on and around the Pine Ridge Indian Reservation. This vast, almost wild stretch of American High Plains is located in the southwestern corner of South Dakota. The reservation is flanked to the north by the stark beauty of the Badlands and to the northwest by the ponderosa-topped Paha Sapa (Black Hills).

As a child, Sherman ate what everyone around him ate — a standard fare prepared with government commodity rations handed out monthly to those living on the reservation as part of a food allotment program going back to the mid-1800s. Sherman points out that while the variety of foods in the commodity allotments are a little better today than they were when he was growing up, they never contain fresh fruits, vegetables or meats and were never meant to be a “nutritional program,” but rather an emergency ration.
