The Growing Potential of Growing Hemp

Hemp farmer Brian Furnish

Brian Furnish is director of Global Production at Ananda Hemp, based in Kentucky.

It’s Time to Consider the Growing Potential of Hemp

Hemp, once a legal and thriving crop in the United States, was dealt a heavy blow with the 1937 Marijuana Tax Act. The Act put heavy tax and licensing regulations on both hemp and marijuana crops, making hemp cultivation difficult for American farmers. The Controlled Substances Act of 1970 proved to be a virtual death knell for the crop, classifying all forms of cannabis as a Schedule 1 drug, making it illegal to grow.

The crop is beginning to make a comeback, however. In the early 1990s, as hemp’s potential uses became more widely known, there was a sustained resurgence of interest in allowing commercial hemp cultivation in America. The Hemp Industries Association estimates an average of 15 percent annual growth in U.S. hemp retail sales from 2010 to 2015, with the majority of this growth attributed to hemp-based body products, supplements and foods.

Compost & The Promise of Microbes

Scientist David C. Johnson Explores Microbial Communities, Carbon Sequestration and Compost

David C. Johnson’s experimental findings and openness to new insights have turned him into a champion of microbial diversity as the key to regenerating soil carbon — and thus to boosting agricultural productivity and removing excess atmospheric CO2. His research, begun only a decade ago, affirms the promise of microbes for healing the planet. It has attracted interest from around the world.

Johnson didn’t come to science until later in life. At age 51 he left a rewarding career as a builder, specializing in custom homes for artists, to complete his undergraduate degree. He planned to use his education “to do something different for the other half of [his] life,” though what he didn’t know. He said a path opened up and opportunities kept coming his way. After completing his undergraduate degree, Johnson kept going, earning his Masters in 2004 and Ph.D. in 2011, both in Molecular Microbiology. With his first advanced degree in hand, he got a job at New Mexico State University, where he was going to school and currently has an appointment in the College of Engineering.

He credits a fellowship program that placed undergraduate students in different labs with sparking his fascination with the composition of microbial communities as a graduate student. Johnson, who once farmed as a homesteader in Alaska, says he was once “an NPK junkie” but considers himself to be “13-years reformed.” Continue Reading →

Windbreak Benefits on the Farm

Windbreak benefits extend beyond reducing wind erosion. Research reveals windbreaks can also be customized to meet your farm management goals, whether it’s increasing wildlife habitat or benefiting visiting pollinators.

Windbreak benefits extend beyond controlling wind to include soil moisture retention and additional wildlife habitat options.

A “national menace” is what Congress called wind erosion during the Dust Bowl. This menace caused an estimated loss of 850,000,000 tons of topsoil and spurred President Roosevelt’s large-scale Shelterbelt Project of planting tree windbreaks across the Great Plains to reduce future wind erosion.

Research shows that reducing wind erosion isn’t the only benefit provided by these windbreaks, and they can be customized to meet your farm’s management goals, whether it’s increasing wildlife habitat or benefiting visiting pollinators.

In a field adjacent to a windbreak, there is an area where a crop yield of 110 percent isn’t uncommon; it’s the area which Charles Barden, professor of forestry with Kansas State University and principal investigator of the Great Plains Crop Yield Study, dubs the “sweet spot in the field.” In this sweet spot, usually found in an area about two times the height of the trees and extending out 12-15 times the height of the windbreak trees, research has found an increase in yield of 23 percent for winter wheat, 15 percent for soybeans and 12 percent for corn.

Hügelkultur Gardening

Hügelkultur (pronounced “hoogle-culture”) is German for “hill culture.” Hügelkultur entails growing crops on a raised, earthen mound that consists of a foundation of fresh or rotting logs and branches covered in layers of manure, compostable materials and soil.

Hügelkultur (pronounced “hoogle-culture”) is German for “hill culture.” Hügelkultur entails growing crops on a raised, earthen mound that consists of a foundation of fresh or rotting logs and branches covered in layers of manure, compostable materials and soil.

Hügelkultur Construction

  • Hügel beds can be made to any length, width or height desired. The average hügelkultur bed is three to five feet tall and can be rectangular, square, round or horseshoe-shaped (keyhole).
  • Beds are typically built on top of the ground and sometimes in 12- to 15-inch deep trenches.
  • Beds are generally free-standing, without any physical support or enclosure, but can be framed at the base with blocks, untreated lumber, logs or hay bales as desired.
  • A mixture of soft (faster-rotting) and hard (longer-lasting) woody base materials usually includes freshly dead or rotting firewood rounds, stumps, branches, brush and twigs.
  • Avoid wood from allelopathic trees like black walnut (for its juglone toxicity); high-resin trees like pine, spruce, yew, juniper and cedar; and hard, rot-resistant woods such as black locust, Osage orange and redwood. Any type of wood with sprouting potential (such as willow) should be completely dead before using.
  • Small branches, twigs, sawdust and coarse woodchips are used to fill voids in the woody base before construction is complete and periodically as the bed breaks down.
  • A simple hügel is covered with three to five inches of rotted manure or compost, followed by another three to five inches of garden soil or topsoil, but this can also include multiple layers of various organic materials in the fashion of a “lasagna-style” garden bed.
  • Hügel beds are ready for planting immediately after construction.

Composting: Join the Revolution

The so-called brandling or humus worm thrives in litter. They enjoy great popularity among a number of experimentally inclined gardeners. What is so special about these small worms?

My theory is that in worm composting or vermicomposting (Greek vermi: worm), we have something completely new that has little in common with conventional composting, and most importantly is superior to any previous method. The final product, worm castings, which is the term for worm excrement, is not comparable to other types of compost. It represents a new level of quality.

At this point, I want to quote the well-known words of former German chancellor Helmut Kohl: “The crucial thing is what comes out at the end.” This applies to humus worms in both the literal and the metaphorical senses. This “new” method is able to meet the modern demands of nature, environmental, and climate protection much better than any previous approach.

There is an ever-increasing discrepancy between the waste of natural power and resources in conventional composting methods (unavoidable losses in the forms of gases and liquids during hot composting) and the growing need to protect nature and the environment (through sustainable development to curb global warming). A solution is desperately needed. Composting is a part of the battle of opinions between humus management and ecological gardening and farming on the one side and Justus von Liebig’s so-called mineral theory, which serves as the foundation of the chemical industry and conventional agriculture, on the other side. The remainder of this book shall demonstrate the superiority of the former in detail.

Regenerative Fiber Farming

It was sheep shearing day on my grandpa’s ranch in the mid-20th century, and all I knew was that I was having fun. Everyone, including Grandpa, was clad in blue denim jeans on this sunny day. Gathered with other neighboring small-scale ranchers, we sheared and then stuffed and stomped wool into the gigantic bag that would be taken to market

organic cotton farming in California

Sally Fox of Vreseis Ltd., a Fibershed producer member in the Capay Valley of California, amidst the organic, naturally colored cotton she has been breeding for over 30 years.

Though considered old-fashioned and outdated in that era of get-big-or-get-out agriculture, small farmers in our area still gathered for shared missions like this. And there was no reason at the time for a kid like me to realize that what we were doing — raising textile fiber (a.k.a. fiber farming) in an Earth-regenerative manner — would become a world mission to support the health of the planet.

Holistic by default, Grandpa’s sheep were rotationally pasture-grazed, the ranch was diversified, and he planted by the moon’s cycles. That’s the only way he’d ever farmed. Yet that type of farming didn’t appear out of an inability to know better. It evolved from a powerful ability to sense what is needed to thrive.

Fast-forward to being a grandparent myself, and climate change adds a sense of urgency for not just our food and fuel to be Earth-restorative, but also our clothing and textiles. The after-harvest processing of fiber must be considered when improving the ecological impact of the textile industry, but eco-farmers serve the initial production of the fiber themselves, and it must happen in a way that also sustains them financially.
