Inorganic Soil Reference Sheet 1.2

Here is the first resource developed from the thread "Introductory Soil Physics". It is a reference sheet defining common inorganic soil types used in bonsai. It expands on the selection discussed in the thread. It is not a recommendation of what one should use in their garden, rather a description of what the choices are. Subsequent resources will contrast the physical properties of these soil types and document how they change as a function of grain composition, grain size, grain shape, sorting and height of the pot.
