Studies on the classification of soils of the Kiama area of NSW

The question "what is soil?" is an important one as it will define the medium that is to be classified, i.e., most classification systems rely on the operational universe to have definite boundaries. The meaning of the term "soil" varies from person to person. Agriculturists view soil to be a medium of solid, liquid and gaseous materials that supports crops and other vegetation (Millar and Turk, 1965). However, plants will grow in water with nutrients, sand dunes, stream deposits (alluvium) and in wind deposited dust (loess). Are these media considered as soil?
