Introduction to Soils in the Environment SOS 3022 Study Guide – Summer 2001 Chapter 3 - Soil formation 1 Be familiar with general characteristics of the diagnostic surface horizons or epipedons: the mollic, umbric, ochric, and histic horizons. 2 Be familiar with general characteristics of the following diagnostic subsurface horizons: argillic (Bt), spodic (Bh/Bs), oxic (A, or B), and calcic (k) 3 Be aware of the distribution of Entisols in the US. (Fig. 3.6) 4 Be aware of the distribution of U. S. Mollisols in the central plains area (Fig. 3.6). 5 Be aware of the predominance of Ultisols in the southeastern U. S (Fig. 3.6). 6 Be aware of the general distribution of Oxisols world-wide. This soil order is not found in the state of Florida (Fig. 3.6). 7 Be aware that most Vertisols in the U. S. are found in Texas (Fig. 3.6). 8 Be aware of the general distribution of Spodosols in the U. S., including much of the "flatwoods" area of Florida. The Florida state soil, Myakka fine sand, is a Spodosol which occurs only in Florida (Fig. 3.6). 9 Be familiar with the 11 soil orders and their relatively degree of weather (Figure 3.4) 10 Be familiar with the 11 soil orders and their main diagonotic charateristics (Figure 3.7) 11 Understand the distribution and abundance of the four major soils in Florida. 12. Understand the two major distinguishing features of the current system of soil taxonomy for the U.S. 13 Note the general structure of the U. S. system of soil taxonomy for soil order to series. 14 Appreciate the diversity and different types of soils that are present in the US. 15 Note the increasing amounts of information conveyed by the following terms: Mollisols --> Aquolls --> Argiaquolls --> Typic Argiaquolls --> Typic Argiaquolls, fine, mixed, mesic. 16 Be able to recognize typical names of soil order, suborders, and great groups. 17. Get familiar with soil survey and soil survey report
