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.

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.
Comments (0)From Annuals to Perennials

Permaculture is all about mimicking natural systems – patterning our agriculture and other critical human needs on the symbiotic processes we observe all around us. If you compare nature’s methods we see that stable natural plant systems are polycultures, and perennial, whereas our modern industrial agriculture is the exact opposite – largely being monocultures and annuals.
But, imagine if the annual crops we rely on the most, grains and pulses, could be made to grow perennially instead. No end/beginning of year ploughing, no annual replanting, etc. It would save enormous amounts of time and energy on cultivation and planting, and allow soils to remain undisturbed for longer, with immense benefits to soil life, structure, organic matter and carbon content.
The video below highlights this out-of-the-box permaculture thinking. The Land Institute in Kansas has been working solidly on engineering annuals into perennials (by way of natural plant breeding – not by gene gun). They take ancient wild, perennial varieties of grains, and cross them with their modern annual counterparts, and repeat, and repeat, until they end up with a harvestable product from a plant that doesn’t have to be resown every year. Or at least that’s the aim. This is still a work in progress, but their purpose is "to develop an agricultural system with the ecological stability of the prairie and a grain yield comparable to that from annual crops".

One of the most influential people in sustainable agricultural systems development is the late P.A. Yeomans. Yeomans went against the contemporary fertility-in-a-bottle school of thought to develop ‘keyline’ concepts of land management that work in harmony with natural land features (working with contours), to maximise water harvesting in the landscape, minimise soil erosion and build lasting soil fertility. His observations and practice led him to design and develop the keyline plow, a deep chisel plow that maximises water infiltration and soil aeration – setting up conditions that soil macro and microorganisms can flourish in – but that doesn’t overturn the soil, with its associated destruction of soil structure and life, as other plows do.
The ABC just ran an interesting spotlight (video – or transcript here if you prefer) where we learn that one of Yeomans’ properties, ‘Yobarnie’, in Richmond, north of Sydney, is facing ‘development’ that would turn this important historical demonstration site into a housing estate. In the 1950s and ’60s the site attracted busloads of people on weekend tours where observers could see the transformation his methods effected and learn about their implementation.

 What Manhattan may have looked like… |
Often, as I’ve travelled and lived in different parts of the globe, I’ve stood on mountains and beaches and looked around, somewhat wistfully, trying to visualise how those landscapes would have looked a few centuries ago. I’m sure you’ve done it too.
Many, if not most, of these places were once vast tracts of old growth forest, with rich diversity in flora and fauna. Natural biological water cleaning systems were in place, as the hydrological cycle was efficient and largely unmolested by man. Most places still had rich, dark soils and no chemicals had yet been employed to stamp out soil life.
These were the days of 280ppm. We lived then with respect, if not even fear, for a nature wide and wonderful – never for a moment thinking we could one day be the cause of these vast and mysterious systems collapsing wholesale.
Comments (0)Market Gardening and Catching Carbon
Fungi, Rehabilitation, Soil Biology, Soil Composition, 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.
Comments (0)Keyline Plowing with Compost Tea Application
Land, Rehabilitation, Soil Biology, Soil Composition, Structure — by Benjamin Falloon September 16, 2009
This article forms part of a series concerning the development of methods of compost tea application via the keyline plow which are being published on taranakifarm.com.
Part I: Introduction
Employing the methods developed by P.A. Yeomans, keyline pattern plowing is a proven component in the job of revitalizing degraded soils. The plow performs deep ripping with minimal plant disturbance. At its most basic this offers many benefits, including opening compacted soils (without destructive tillage), breaking up the hard pan, allowing moisture and oxygen to re-activate soil life, thus restoring fertility. When used in concert with controlled grazing or mowing through a managed cycle, top soil is built rapidly.
In the related field of soil biology, Dr Elaine Ingham (the eminent biologist) has made breakthrough discoveries studying soil life and developing methods of brewing compost tea. Her work promotes the pressing need to re-populate our damaged soils with the necessary microbial biota. Without the essential micro organisms our soils cannot develop balance. A balanced soil offers fertility, that builds through the exchange for nutrients that is the tireless work of soil life. A multitude of symbiotic connections evolved in harmony.

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink. – Samuel Coleridge (1772-1834). The Rime of the Ancient Mariner, II
If you look down on our earth from space, the predominant colour is blue. The surface of our earth is approximately 70% water. In that respect, perhaps our planet would have been better called the Ocean, than the Earth. Yet, excepting expensive, energy intensive and environmentally problematic desalinisation techniques (PDF), we cannot use it for our daily personal water intake requirements.

Soil – the substance you walk on, build on, and live from – provides your food, clothing, and even the air you breathe. It gives warmth, shelter, and the goods you possess. Soil is, I believe, a substance that is under-acknowledged, and also under attack, and its misuse is contributing greatly to the excessive release of CO2 into our atmosphere – making it a large contributor to global warming. Therefore, I felt it high time we came to its defense. Here goes.
