Bone Sauce: A Tool for Deterring Browsing

Posted by & filed under Food Forests, Food Plants - Perennial, Plant Systems, Trees.

Applying the bone sauce Bone sauce is a product of the destructive distillation of bones — a process which separates the volatile organic components (aka bone sauce, or Dippel’s oil) from the inorganic components (aka bone char — mostly calcium, carbon and phosphorous compounds). Bone sauce has a potent smell, somewhere between wood-creosote and rancid… Read more »

Building Up Soil for a Nutrient-Rich Raised Bed

Posted by & filed under Compost, Plant Systems, Soil Biology, Soil Composition, Structure, Urban Projects.

All photos by David Ashwanden A lot of permaculture involves utilising waste streams and turning problems into solutions, and I often bring these into practice by looking at what’s available around me and how I can use it effectively. With this in mind, having come across some old bath tubs, I decided to create some… Read more »

Fernglade Farm – Autumn Update (May 2014, Victoria, Australia)

Posted by & filed under Demonstration Sites, Food Forests, Plant Systems, Trees.

Well, the summer just past was interesting. Heat and drought were constant companions in all parts of the Australian continent other than the Northern Territory. Down in the south eastern corner of the continent the farm here had to deal with 10 days of temperatures exceeding 40°C (104°F) during January and February. At one point… Read more »

A silk tree in my garden, serving as living trellis to arctic kiwifruit; also shade provider for shade crops including currant, mayapple, fuki, and edible hosta. Also fixes nitrogen. Rafter Ferguson’s recent excellent article “Permaculture for Agroecology” (PDF) challenges the permaculture movement to read up on what’s happening in related fields like agroecology and agroforestry….

Recently, I had the honor of attending a national conference on cover crops and soil health. The conference was held in Omaha, Nebraska on February 17th to the 19th, sponsored primarily by the Howard G Buffett foundation and SARE (Sustainable Agriculture and Research Education). The attendees represented university specialists, seed vendors, farmers, non-profit groups, and… Read more »

Banana Circles

Posted by & filed under Biological Cleaning, Food Plants - Perennial, Irrigation, Plant Systems, Waste Water, Water Conservation, Water Harvesting.

Banana circles can be used in tropical and sub-tropical areas to utilise waste water, run-off or overflow from rainwater tanks, and even urine waste from dry composting toilets. It is possible to use other plants in a similar system, but bananas are an excellent choice as they are very heavy feeders and also need a… Read more »

Does Comfrey Really Improve Soil?

Posted by & filed under Medicinal Plants, Plant Systems, Soil Biology, Soil Rehabilitation.

All of us who have studied permaculture have heard some impressive claims about comfrey. It is a dynamic nutrient accumulator; it improves the soil; it is “a slow motion fountain” of nutrients, bringing them up from the subsoil to improve the topsoil. We’ve heard lots of anecdotal evidence, but where is the empirical data for… Read more »

Swale Pathways (Tasmania, Australia)

by Good Life Permaculture Diagram of a traditional swale system Hobart is Australia’s second driest capital city (Adelaide’s first) so catching and storing water is often on my mind. Annually we get approximately 615mm, most of which arrives in the cooler months in and around Winter. During Summer our soils will dry out so ferociously… Read more »

Advanced Cell Grazing with Geoff Lawton

Trailer only – watch full video here! Last year on Permaculture News there was an excellent article on Advanced Cell Grazing by Nick Burtner who documents the circular cattle lane-way on Geoff Lawton’s 66 acre Zaytuna Farm. Geoff devised a system of easy to install temporary electric-fenced cattle lane-ways that lead to over 38 grazing… Read more »
