The Art and Science of Making a Hugelkultur Bed – Transforming Woody Debris into a Garden Resource

Compost, Conservation, Fungi, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure, Water Harvesting — by Melissa Miles August 3, 2010


Wooden debris will decompose faster,
(and be transformed into a resource)
when hugelkultur techniques are
employed.

Used for centuries in Eastern Europe and Germany, hugelkultur (in German hugelkultur translates roughly as “mound culture”) is a gardening and farming technique whereby woody debris (fallen branches and/or logs) are used as a resource.

Often employed in permaculture systems, hugelkultur allows gardeners and farmers to mimic the nutrient cycling found in a natural woodland to realize several benefits. Woody debris (and other detritus) that falls to the forest floor can readily become sponge like, soaking up rainfall and releasing it slowly into the surrounding soil, thus making this moisture available to nearby plants.

Hugelkultur garden beds (and hugelkultur ditches and swales) using the same principle to:

A ‘New’ Discovery – Soluble Nitrogen Destroys Soil Carbon

Compost, Economics, Fungi, News, Plant Systems, Rehabilitation, Society, Soil Biology, Soil Composition, Soil Conservation, Structure — by Craig Mackintosh PRI Editor July 27, 2010

How many times must we ‘discover’ something we’ve discovered before – particularly when our lives and our futures depend on reacting appropriately, and shaping society, to incorporate the lessons learned?

One of the most transformative experiences in my life was from studying soil science many years ago. Getting something of an understanding of the inner workings of that thin skin which covers our earth created thought-connections in my mind that had me looking at the world in a profoundly new way.

Soil Carbon – Can it Save Agriculture’s Bacon?

by Christine Jones, PhD

The number of farmers in Australia has fallen 30 per cent in the last 20 years, with more than 10,000 farming families leaving the agricultural sector in the last five years alone. This decline is ongoing. There is also a reluctance on the part of young people to return to the land, indicative of the poor image and low income-earning potential of current farming practices.

Agricultural debt in Australia has increased from just over $10 billion in 1994 to close to $60 billion in 2009 (Fig.1). The increased debt is not linked to interest rates, which have generally declined over the same period (Burgess 2010).

1994-2009 vs interest rates (%pa)

The financial viability of the agricultural sector, as well as the health and social wellbeing of individuals, families and businesses in both rural and urban communities, is inexorably linked to the functioning of the land.

There is widespread agreement that the integrity and function of soils, vegetation and waterways in many parts of the Australian landscape have become seriously impaired, resulting in reduced resilience in the face of increasingly challenging climate variability.

Agriculture is the sector most strongly impacted by these changes. It is also the sector with the greatest potential for fundamental redesign.

Measuring Soil Carbon Change

Measuring Soil Carbon Change
2mb PDF

Thanks to Darren Doherty for the head’s up on this new draft document from the Soil Carbon Coalition on measuring changes in soil carbon levels – the key indicator of soil health and fertility.

As we all (should) know well, land use changes over the last several centuries have significantly increased atmospheric CO2 levels. Soil mismanagement, which has increased in tandem with our burgeoning human population, has released mammoth amounts of carbon from the soil, where it is a positive, into the atmosphere, where it becomes, in its present excessive levels, a negative instead. Correct soil management, in contrast, can play a significant role in reversing that trend by pulling excess atmospheric CO2 out of the sky, through photosynthesis, and returning it to the soil in humus, the stable, final state of decomposition of organic matter – thus transforming excess CO2 from being a pollutant into a rich habitat for the micro- and macro-organisms that are the foundation of all life on this planet. Permaculture, through its favouring small scale, low-to-no till polycultures, and where the soil is always protected by a ’skin’ of plant or mulch cover, and maintained by appropriate naturally harvested moisture levels, is a powerful system for restoring the Gaia state of carbon balance.

The Story of Soil

Compost, Fungi, Rehabilitation, Salination, Soil Biology, Soil Composition, Soil Conservation, Soil Erosion & Contamination, Structure — by Rob Avis June 17, 2010

by Rob Avis

What is the difference between soil and dirt?

Soil is alive. Dirt is dead. A single teaspoon of soil can contain billions of microscopic bacteria, fungi, protozoa and nematodes. A handful of the same soil will contain numerous earthworms, arthropods, and other visible crawling creatures. Healthy soil is a complex community of life and actually supports the most biodiverse ecosystem on the planet.

Modern soil science is demonstrating that these billions of living organisms are continuously at work, creating soil structure, producing nutrients and building defence systems against disease. In fact, it has been shown that the health of the soil community is key to the health of our plants, our food and our bodies.

Why is it then, that much of the food from the conventional agricultural system is grown in dirt? The plants grown in this lifeless soil are dependent on fertilizer and biocide inputs, chemicals which further destroy water quality, soil health and nutritional content.

How did we get here? How do we turn this around? This is the Story of Soil….

Permaculture Soils DVD Trailer

Compost, DVDs/Books, Fungi, Rehabilitation, Salination, Soil Biology, Soil Composition, Soil Conservation, Structure — by Craig Mackintosh PRI Editor June 9, 2010

It’s a wonderful thing to behold when permaculture passion and top-notch multimedia skills intersect in world-changing ways. Frank and Jane Gapinski of Ecofilms have spent countless hours working up highly educational and highly watchable productions for the PRI for a few years now. It all began with the initial Greening the Desert clip that took the world by storm; then followed the Water Harvesting DVD, the Food Forest DVD, and very recently the Introduction to Permaculture Design DVD. The incredible uptake of these films is living, encouraging proof that there is a new generation emerging who understand what needs to be done, and want to know how to do it!

But wait, there’s more! We’re now awaiting the soon-to-be-released Permaculture Soils DVD! This DVD gets to the very heart of what’s needed for a permanent culture, examining that magical muck that is the foundation of all the aforementioned productions. This work shares insights from Geoff Lawton’s two and a half decade’s worth of worldwide experience in soil creation – an experience gained in some of the world’s most inhospitable environments – helping to make the impossibly complex come to life in wondrously understandable ways. I personally think that holistic studies in soil science should be compulsory, foundational elements for every school syllabus – and that if they had been we wouldn’t be in the mess we’re in today – and we hope this DVD will go some distance in making up for this major shortfall in mainstream education.

Check out the trailer, and then stay tuned for future updates on release.

Great Soil Biology – The Silver Bullet

Talking with Soil Biology Wizard, Paul Taylor

When you put the Permaculture lens on and look at where our food comes from there are hundreds of dead canaries trying to warn us it’s time to wake up and make a change to something better.

As I look closer I realise the industrial food system is a planet destroying system that deprives people of health and well-being, putting more value on short-term profits and perfect looks than nutrient content and building resilient communities that have sustainable access to food. Not only that but it appears to be edging towards collapse as failing unproductive farms are propped up by more and more chemicals and machines that run on not-so-cheap-anymore oil.

So just as it was all looking a little bleak I was lucky enough to speak with Paul Taylor from Trust Nature. He is a true genius when it comes to understanding soil biology and restoring land back to fertility.

Tropical Soils: Less is More in Fast Carbon Pathways, but Only with Standing Forest

Courses/Workshops, Deforestation, Demonstration Sites, Education Centres, Fungi, Plant Systems, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure, Trees — by Planet People Passion May 16, 2010

The Amazon rainforest is one of the most amazing displays of symbiotic relationships one can experience in the world. This complex and layered eco-system thrives through the many systems and cycles that interweave through the layers of canopy, creating one of the most bio-diverse displays of life on the planet. Nature designs the most magnificent Permaculture systems – it is quite an experience to spend time in this magical place and humbly observe her teachings.


Amazon rainforest boundary

Observing the thriving and abundant rainforest, it is hard for some to comprehend why neighboring agriculture in the region experiences quite the opposite affect, but the answer is quite simple – it’s all about the soil.

Regeneration – an Earth Saving Evolution

Compost, Conservation, DVDs/Books, Food Shortages, Fungi, Irrigation, Regional Water Cycle, Rehabilitation, Salination, Soil Biology, Soil Composition, Soil Conservation, Soil Erosion & Contamination, Structure, Water Contaminaton & Loss, peak oil — by Craig Mackintosh PRI Editor May 8, 2010


Regeneration – an Earth
Saving Evolution

How biological farming builds healthier
soils, healthier plants, healthier animals
and certain hope in an uncertain world.

In a kind of army style ‘about-face’, society is increasingly turning away from the reductionist, extractive agriculture that rushed onto the world after WWII. Today people are, thankfully, realising that you cannot convert biodiverse natural systems into monocultures – into a factory floor environment – and expect success. With the soils that support all life on this planet getting rapidly eroded and diminished in critical organic matter, people are realising that farming is far more about biology than it is about chemistry, more about feeding the soil than feeding the plant, and are realising that our futures, our very survival, depends on our coming to grips with biological processes and learning to harness them.

I’ve just uploaded the new Regeneration – an Earth Saving Revolution DVD to our online store. This DVD examines the thoughts and work of some of the many individuals who are now leading the way forward in farming techniques that are simultaneously highly productive and entirely sustainable. It’s an inspiration-packed DVD that’s worth circulating to all.

Our survival now truly depends on how fast this kind of information can be made to pervade society at all levels, and how rapidly we can rebuild society to accommodate, integrate and harmonise with it.

Make Your Own Worm Farm from Car Tyres

Compost, Fungi, Plant Systems, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure, Waste Systems & Recycling, Working Animals — by Craig Mackintosh PRI Editor April 8, 2010

A certain truck driver in Asia has discovered the value of good road-hugging (or bridge barrier-hugging, as the case may be) tyres.

But, that’s not the topic of this post. Here, instead, we offer the suggestion of taking well worn tyres not capable of such extreme feats, and putting them to other worthwhile purposes – like feeding your garden with nutrient rich worm casts.

At Zaytuna Farm we use a couple of old bathtubs for this purpose, but if you don’t have a bathtub at your disposal, this simple car tyre system (700kb PDF) looks like a great alternative.

Greening the Desert II – Final

Aid Projects, Biological Cleaning, Compost, Conservation, Demonstration Sites, Education Centres, Food Forests, Food Plants - Perennial, Fungi, Irrigation, Plant Systems, Rehabilitation, Salination, Soil Biology, Soil Conservation, Trees, Water Harvesting — by Craig Mackintosh PRI Editor December 11, 2009

The Greening the Desert II video I shared with you recently was edited in Jordan. Now that I’m back at my desk again I’ve had time to edit it slightly. I’ve added the original five-minute Greening the Desert clip in to the front of it, to ensure viewers have context for Part II (and we’ve also had requests for both to be made available together), as well as cut a few minutes out of Part II to keep it flowing a little better. You can not only watch online below and embed on your own websites (click for embed code at top right of video screen), but it’s also available for download, so those who’d like to have a ‘hard copy’ to circulate are welcome to download, burn to disk or transfer to USB key, etc., and circulate freely.

Download: You’ll see the option to download the 913 megabyte MP4 file at bottom right side of this page.

YouTube: The video can also be watched on YouTube, in four segments, here, here, here and here.

Greening the Desert II (including Part I) – Greening the Middle East
(Duration: 36 mins)
Tips for playing: If it’s slow to load, turn off High Definition (HD) on the player.
If you still have problems, click play (on low or high def) and then after it’s started,
click on pause. The video will then continue to buffer into your computer.
Play once fully loaded.

I would like to take the opportunity to thank Kelly Kellogg at this juncture. Kelly donated initial funding that enabled the purchase of the land for the Jordan Valley Permaculture Project site (aka ‘Greening the Desert – the Sequel’). But, upon watching the Greening the Desert Part II video, Kelly was inspired to donate an additional $20,000. These gifts are very encouraging to us as we try to solve problems at source (teach a man to fish…). Others who may feel inspired to donate to help us move this work forward faster can do so here.

Keyline Plowing with Compost Tea Application

Compost, Fungi, Rehabilitation, Soil Biology, Soil Conservation, Structure — by Ben Falloon November 29, 2009

This article forms part of a series concerning the development of methods of compost tea application via the keyline plow which are published on taranakifarm.com.

Read the first installments here.

Part IV: Re-Inventing the Herbicide Tank – Giving Destructive Equipment New Purpose

Compost tea brewing requires the use of specialist equipment. Especially when you intend to apply tea to hectares of paddocks. In my case, I’ll be making tea using a 1000L brewer supplied by Trust Nature Pty Ltd. The brewer tank is a little large to mount on the keyline plow, so an ‘application’ tank is required. This is a smaller tank, fitted with a pump and plumbing necessary for application during keyline plowing.

A wise person once said that soil is not only more complex than we know, it is more complex than we can ever know! The good news is humans have lately achieved a level of practically applicable knowledge and experience in soil biology to be absolutely capable of massive, positive impacts on sustainable soil use world-wide! It is undoubtedly true that we’ll never know everything, but no matter – we already know enough to get very, very busy!

Market Gardening and Catching Carbon

Fungi, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure — by Hugh Lovel October 4, 2009

After driving all night from my North Georgia market gardens I arrived just before seven in the morning at the Indianapolis hotel where the ACRES U.S.A. Convention was to be held. The lines at the hotel desk were so long I left my colleague, Lorraine Cahill, to check in while I headed for the restaurant. I needed a steaming mug of coffee and a bite of breakfast to start my day. Otherwise I was in danger of fading away. Growing market veggies for 26 weeks for restaurants, markets and box subscribers had, thankfully, just come to a close before driving all night to reach America’s most unforgettable and inspiring convention. I didn’t want to miss a minute of it, but I had a booth to set up when the trade show opened and I needed more push than I had at the moment.

Six Ways to Save the Planet with Mushrooms

Fungi, Plant Systems, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Soil Erosion & Contamination, Structure — by Craig Mackintosh PRI Editor July 28, 2009

No, we’re not talking about your average portobello mushroom here, found on pizzas the world over. The topic of this discussion is:

mycelium noun the white threadlike mass of filaments forming the vegetative part of a fungus

Whilst sounding tiny in both size and significance, it is not:

Is this the largest organism in the world? This 2,400-acre (9.7 km2) site in eastern Oregon had a contiguous growth of mycelium before logging roads cut through it. Estimated at 1,665 football fields in size and 2,200 years old, this one fungus has killed the forest above it several times over, and in so doing has built deeper soil layers that allow the growth of ever-larger stands of trees. Mushroom-forming forest fungi are unique in that their mycelial mats can achieve such massive proportions. – Paul Stamets, Mycelium Running

Watch the clip to learn more about these fascinating fungi – organisms totally ignored by industrial agriculture, but which are incredible allies as we seek to decontaminate and restore soils and other habitat.
