Popis: Apart from the engineering approach to soil as movable regolith, most specialists who study soil view it as a plant-linked, land-only, and Earth-only entity whose character and properties are explained by a mix of four environmental factors—climate, organisms, relief, and parent material—that operate over time. These factors function to produce soil, where S=f (cl, o, r, p, t …). This relationship constitutes the five-factors, “clorpt,” explanatory model of soil formation that lends itself to the survey, classification, and mapping of soil for agricultural and environmental purposes and aids in soil valuations and soil conservation-management needs. In geomorphology and Quaternary research, it has met success in soil chronosequence and age-dating studies. But inasmuch as soil is the most complex and unparsimonious of all natural science entities, is any model so conceptually endowed that it allows a deep understanding of the full range and nuances of soil-forming processes? Can a conventional mod...
