The work presented in this paper represents an attempt made by using chemical and physical methods to find the reasons for the variations in site quality which appear in soils bearing a heath flora. In order to do this, the soil samples were collected from under four different heath communi-ties; namely, Calluna, Desohampsia, Ulex, and Pteris*. These communities were selected since field observations on planted areas had Indicated tnat the Calluna and the: Desohampsia communities could, in general, be regarded, as indicating soil conditions somewhat less favourable for tree growth than were those indicated by the whin and the bracken communities. Several complete profiles and a number of " short " profiles were opened under each of these communities and after field descriptions had been prepared, representative samples of the layers were taken for analysis. Although all of the soils belonged to the same group: the podsols: it soon became evident that there were differences in the type of podsole and that these differences were related, to a certain extent, to the vegetative cover. Accordingly, in the paper a des-cription of each profile is presented and these descriptions are followed by the results of the laboratory analyses and their bearing upon field observations and the problems of afforestation sites. Calluna commonly known as the ling, Pteris as the bracken fern, and Ulex as the whin or the gorse. In conclusion, the main characteristics of the soils from the ecological, physical, and chemica1 standpoints are summarized and discussed, and, on. the basis of the results obtained, suggestions are made as to the possibilities of improving these undesirable heath types.
