Summary A review is made of the trends in soil classification in Tanzania, indicating the need for an alternative to the traditional catena concept. An attempt to use the 7 th Approximation is reported, in view of the demand for high category soil classification, using forty‐three typical soil profiles and discussing the particular problems related to placing three intimately studied profiles into the orders Alfisol, Ultisol, and Oxisol. An unrevised version of the 7 th Approximation is not recommended for use in Tanzania. However, by using the central concepts of the system and further defining the soil classes at all levels, the use of the 7 th Approximation could greatly assist in the assessment of the nation's soil resources and the ultimate development of agriculture in this country.
