What is soil? Most people call it dirt. It brings to mind pictures of children's dirty faces or dirty floors or worse yet, germs and bugs and other nasties. And, in some ways those pictures are correct. But soil is so much more.
Soil is comprised of minerals, organic matter, microorganisms, space and water
The minerals are what we normally think of when we consider "dirt". It is really broken down rock. The type of rock determines the type of minerals available in the soil. The texture can be very fine clay, slightly larger silt, gritty sand or even rocks of various sizes.
