Soil: What it is and where it came from

It has always amazed me how many of us are ignorant of the earth we stand on.

Even gardeners are often confused about where their soil came from, what type it is and how it can affect the plants that they grow.  Many will follow standard instructions on adding sand to clay to help it drain, and lime to sweeten it, without really understanding why they're doing it or the effect these actions may have.

So, to try and increase our knowledge a bit, this is going to be the first of a series of posts designed to give the average Joe (or Wayne if you're an Aussie!), a good working knowledge of soil.
