What Is Jenny’s Equation? ∎ Jenny’s state factor equation for soil genesis: S = f (C, O, R, P, T, . . .) C = Climate O = Organisms R = Relief (topography) P = Parent Material T = Time . . What is the Clorpt equation? The standard conceptual model for pedology, soil geomorphology,
How Do You Classify Soils? Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay. Sandy soil contains particles that can be seen with the naked eye and feels gritty when rubbed between the
How Do You Classify Soil According To USCS? Coarse grained soils: In these soils, 50% or more of the total material by weight is larger than 75 micron IS sieve size. Fine grained soils: In these soils, 50% or more of the total material by weight is smaller than 75 micron IS sieve size. How
