Since 1972 reconnaissance soil surveys at a scale 1:100.000 are carried out in Kenya by the Kenya Soil Survey. Reconnaissance soil maps and the associate multi-purpose land evaluation form the logical basis for the selection of areas to be developed for specific types of land use. Once such areas and their preferred land use are identified, these parts of the survey area may be covered by more detailed soil surveys, accompanied by a land evaluation in more quantitative terms, the reconnaissance soil survey can however also be used as a first basis to locate and extend experiments on soil fertilizing, and for the programming of soil conservation and soil management in general. The comprehensive character of the land evaluation on the basis of reconnaissance soil surveys implies that not only the soils themselves are studied and mapped but also the topography, the climatic conditions, the vegetative cover, the present land use, and the incidence and hazards of soil erosion. Concurrently and in association with agroeconomists, an identification and characterization is provided of the relevant land utilization types i.e. the physically possible and socially (and economically) promising forms of land use. Methods and procedures used in the inventory of the soil and land resources and subsequent land evaluation are described: examples are taken from the soil survey of the Kwale region, an area at the coast of Kenya.
