“…It serves to simplify complex relations among the soil-forming factors in mathematical terms and provides a basis for interpreting soil attributes in terms of genetic history. However, from a pragmatic standpoint, the equation has never really been solved (Crowther, 1953;Kline, 1973;Phillips, 1998).…”

“…Rather, the soil is a continuous multivariable natural body that changes at different rates and along different pathways into diverse combinations of the defining attributes (Joffe, 1936). Crowther (1953) emphasized the temporally dynamic natures of many key soil attributes as yet another dimension of complexity in an already conceptually bewildering entity. Joel (1926) and Marbut (1935) believed that the study of soils could not advance as a science until a generally accepted classification system, based on the soil itself, was developed.…”

Effects of species on nutrient cycles and soil change

The choice of species to be favoured in forest management is subject to several considerations, among them the possibility of adverse effects on site productivity. Information on this possibility is reviewed from three viewpoints: nutrient cycling, soil genesis and classification, and relatively short-term (i.e. within one generation) changes in soil properties and growth rate. Nutrient cycle models describe flows between soil and plant components of ecosystems but generally can reveal little about variation in nutrient supply over the life of a stand. Profound changes in profile characteristics and mineral weathering occur on a time scale of millennia and can scarcely be expected within a single generation of one or another species. Many reported comparisons of species effects on soil profile development, physical structure, or nutrient status are invalid for a variety of reasons, including inadequate perception of inherent soil heterogeneity. Claims of decreased yields resulting from successive generations of conifers are not borne out by recent studies. Finally, maximum changes in soil due to choice of species appear minor in comparison with the mechanical and chemical impacts associated with present day intensive forest management.

“…Landform shape and composition both influence the rate and volume of water movement into and through the soil (Huggett, 1975). The seasonal distribution of water is the driving force of soil genesis (Crowther, 1953).…”
