Photos © Ingrid Pullen Worms are an essential part of a permanent agricultural system. At Zaytuna Farm worm farming has been developed into a very productive system. The feed stock we use is the contents of composting toilets and animal manures. The worm farm product is included in the potting mix for the plants grown… Read more »

This stunning piece of cinematography gives us a close-up view of the type of rainforest complexity and biodiversity we can only hope to imitate as permaculturalists.
How the same fractal pattern found in a tree is perpetuated throughout its home forest. Fascinating information for permaculture design. From the documentary, Fractals – Hunting the Hidden Dimension.
Dutch clover cover crop between cabbage rows Nitrogen is a component of protein and DNA and as such, is essential to all living things. Prior to the Industrial Revolution, around 97% of the nitrogen supporting life on earth was fixed biologically.

In this documentary a legendary civilization thought to be too good to be true on the basis of the stories told by the Spanish explorer Francisco de Orellana, is found to be a real part of history. We can separate fact from fiction here, in that the golden riverbanks the Spaniard told of were not… Read more »

In fact, he contends they can rescue it in several different ways. There are the medicines to be derived from fungi, probably more than we can yet imagine. Fungi for insect pest… Read more »
This short article is a chapter from my book “Fertilizer for Free: How to make the most from Biological Nitrogen Fixation”. One important question permaculture designers should ask themselves: Is there anything you can do to increase the rate of biological nitrogen fixation? The benefits of having more nitrogen rich organic matter in the soil… Read more »
Size of a pumpkin leaf: 42 cm, that’s 16.5″. Not bad for a sandy soil! One of the problems a lot of people have is how to improve the fertility of sandy soil. One solution is to add more organic matter (compost, manure, wood chips), but unfortunately if you live in a hot and humid… Read more »

But there is no natural law which dictates this to be the only, or even a preferable way in which to propagate plants. While in-situ propagation from seed… Read more »
