  • morphology and composition of soils - soil morphology, form, structure and organization of soil material;
  • soil composition, chemical, physical - and mineralogical measurements, within pedons;
  • macromorphology, best evaluated - from in situ examination of soil profile;
  • recognizing soil horizons - describing their properties;
  • rupture resistance, evaluation of strength of soil - withstanding an applied stress;
  • stickiness, tendency of wet soil material - to adhere to other objects;
  • combination horizons, recognized - distinct parts of two master horizons, recognizable in horizon;
  • use of prime and caret symbols - same combination of letters and numbers for horizon designations;
  • mineralogical composition - sand and silt mineralogy;
  • soil micromorphology, interpretation - and measurement of soil components and features smaller than seen with naked eye


This chapter contains sections titled:
