Models of soil formationentists have a different view again, or rather several different views (Johnson & Watson-Stegner 1987). These varied views of soils are in effect different theoretical bases for their study. So far, in describing various features and kinds of soils, they have been considered as if they were natural

Organismstease apart. Indeed, some geographers refer to “forest climates” or “grassland climates.” Consideration of vegetation as a factor in soil formation has been criticized as not a clearly independent variable from others, such as climate and topographic position. The concept of a “grassland climate” ma

Time as a factorcal representation. These kinds of relationships are called chrono-functions. Some processes of soil formation, such as podzolization, are simple and rapid enough to be studied by means of laboratory experiments (Fisher & Yam 1984). Most soil-forming processes are too slow for such an approach, and

A long-term natural experiment in pedogenesise factor chosen for study. In many cases this is difficult. The effects of climate, for example, may not be easy to tease apart from those of vegetation. For the study of the role of particular factors in the formation of paleosols, it is also important to select examples where other factors of the
