In conventional classification of soil profiles the relative positions of pedogenic horizons within the profile are usually considered. In this paper numerical classification methods are described which consider the relative positions of samples in the profile. The methods are applied to twenty profiles, each described by eight field properties and eight laboratory tests determined on samples taken from 10 fixed depths. Results of these two numerical classifications are compared using an ordination procedure. Advantages and pedological applications of the methods are discussed.
