This decision tree has been designed with the purpose of application with the Australian Soil Classification, which was created by R.F.Isbell. This work takes no credit for the creation of the classification system, it is simply a tool to be used to aid the process of classification. I recommend that any user has access to a copy of the book. Click here to order one online. I am using the 1st addition.
