These descriptions were made following the Guidelines for Field Soil Description of WRB (IUSS Working Group WRB 2006; FAO 2006). A soil horizon is a layer (which is different in depths), approximately parallel to the surface of the soil that is distinguishable from adjacent layers by a distinctive set of properties produced by the soil-forming processes (i.e., pedogenesis)
Notes: L loam, C clay, CL lay loam, WE weak, MO moderate, ST strong, ME medium, FM fine and medium, CO coarse, SB sub-angular blocky, SB GR sub-angular blocky parting to granular structure, MA massive, FR friable, FM frim, FRF friable to firm, ST sticky, SST slightly sticky, Pl plastic, SPL slightly plastic, C clear, G gradual, D diffuse, S smooth. Transportic qualifiers are mainly sandy sand ...UU3, UU5 = Gravels and course sandy material and T for termite channels.
