Summary In the arid environment of South Arabia the soils (sedosols, see Part I) are not significantly affected by pedogenetic processes. Classification of these soils is therefore in accordance with the principles outlined in Part I, being based upon a consideration of the mode of deposition rather than on considerations of pedo‐genesis. Sedimentary geomorphology, soil classification, soil mapping are discussed for two areas of South Arabia. Mapping purity was satisfactory and reliability was probably greatest in series that were wholly anthropic or wholly natural in origin. In classifying land for single‐flood irrigation agriculture, the total readily available moisture capacity is the major land classification factor. It is a function of texture and effective depth, modified in places by severe stratification.
