WebState Equation for Soil Formation Clorpt or Corpt is a mnemonic for Hans Jenny's famous state equation for soil formation: S = f (cl,o,r,p,t,& .) S is for soil, c (sometimes cl) represents climate, o organisms including humans, r relief, p parent material, or lithology, and t time. WebThe equation reads: s = f (cl,or,r,p,t...) where s is any soil property, cl is climate, or is organisms, r is relief, p is parent material and t is the duration of the soil-forming process.
