Here’s my second mini-article featuring favourite parts of the Permacultrue Design Course.
This week it’s soil.

It’s easy to not think about soil too much – what is there to know? It’s brown and sticky and plants grow in it. Anything else??
I have grown to love and appreciate soil in recent years. It is one of the most undervalued resources and we’re in great danger of destroying it. Soil is highly complex, has taken thousands of years to make, is home to almost unbelievable amounts of micro-organisms and is absolutely vital to all life on land. Without it, we would have no trees or plants, and without them there wouldn’t be any animals.
Soil is a mixture of :
* Small rock particles – sand, silt and clay
* Humus – broken down organic matter
* Air (vital for plant health!)
If the soil is healthy, it will also be chock full of micro-organisms – millions in every handful.
Soil is getting made all the time, but soil erosion is a massive, modern problem. Mechanised farming exposes our soil to rain and wind, washing it down rivers into the sea. In North America, an estimated 1/3 of all top soil is now at the bottom of the oceans.
Permaculture can provide methods of producing food which build soils rather than depleting them – essential skills for a sustainable future.
