Jenny's general soil forming equation

WebSoil = f (climate, parent material, relief, organisms, time) This tells us that if the soil pedons at two different points on the landscape have, in all details, the same kinds and intensities of soil properties, the soils of the two places are the same and they have had the same developmental history. WebJun 1, 2024 · Following the physical chemists, Jenny (1930) wrote, for soil N: N = f (T,H), and dN = (dN/dT)HdT + (dN/dH)TdH where T = temperature and H = humidity. The boldness of this concept, adopted from the introductory chapters of Lewis and Randall’s book, is remarkable in hindsight.
