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.
Comments (1)Keyline Plowing with Compost Tea Application

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.

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.

Comments (8)Phosphorus Matters II – Keeping Phosphorus on Farms
Compost, Fungi, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation — by Marcin Gerwin July 23, 2009
Editor’s Prelude: Peak Phosphorus barely registers alongside it’s more gregarious, attention-getting bigger brother, Peak Oil. Yet, the implications are even more dramatic. While both peaks are associated with massive food shortages, unmitigated Peak Phosphorus would easily win the award for best disaster.
The latest research tells us that Peak Phosphorus is an issue we cannot afford to ignore any more:
… a global production peak of phosphate rock is estimated to occur around 2033. While this may seem in the distant future, there are currently no alternatives on the market today that could replace phosphate rock on any significant scale. New infrastructure and institutional arrangements required could take decades to develop.
While all the world’s farmers require access to phosphorus fertilisers, the major phosphate rock reserves are under the control of a small number of countries including China, Morocco and the US. China recently imposed a 135% export tariff on phosphate rock essentially preventing any from leaving the country. Reserves in the U.S. are calculated to be depleted within 30 years. Morocco currently occupies Western Sahara and its massive phosphate rock reserves, contrary to UN resolutions. – Western Sahara Resource Watch

Keeping Phosphorus on Farms – by Marcin Gerwin (the sequel to ‘Closing the Phosphorus Cycle‘)

“Next to clean water, phosphorus will be one the inexorable limits to human occupancy on this planet” wrote Bill Mollison in Permaculture: A Designers’ Manual more than 20 years ago (1). It is that important that we design phosphorus recycling into our food systems. Phosphorus is an essential element for growing crops and no porridge, chocolate bar or cherry jam can be made without it.

Part One: Closing the Phosphorus Cycle

It might sound ridiculous, but for every container of bananas, coffee, tea or cocoa imported, we should send back a shipment of a fluffy, earth-like smelling compost. Why is that? With each container of food we import nutrients taken up by plants from the soil. We import calcium, potassium, magnesium, boron, iron, zinc, molybdenum, copper and many others. One of the essential elements imported in food is phosphorus. For every ton of bananas we import 0.3 kg of phosphorus, for every ton of cocoa it’s 5 kg and for ton of coffee it’s 3.3 kg of phosphorus. Tea is a bit more complicated, because the amount of phosphorus depends on the origin of tea – for example in 1 ton of tea leaves harvested in Sri Lanka there are some 3.5 kg of phosphorus, while tea from South India contains 6.6 kg of phosphorus (1).
Comments (6)Soil – Our Financial Institution

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.
