Summary
Vegetation formations (BOG, FEN-MARSH, and SWAMP) and types within formations for the Northern Clay Section of Ontario were compared on the basis of the quantities of five macro-nutrients in their peats: N, P, K, Ca, and Mg. The comparisons revealed that the formations, except FEN and MARSH, are clearly distinguishable on this basis. Heterogeneity between formations or between some of the types within formations, and trends in statistical indices for sequences of types, suggested that the original classification of Jeglum et al. (1974) based on vegetation conveys reliable information about soil nutrient contents.
Résumé
Les formations végétales (TOURBIÈRE, PRAIRIE MARÈCAGEUSE, MARAIS) et les types de sol à l'intérieur de ces formations de la section des Argiles du Nord de l'Ontario furent comparés d'après les quantités de cinq macro-agents nutritifs contenus dans leurs mousses: N, P, K, Ca et Mg. Les comparaisons indiquèrent que les formations, sauf celle des PRAIRIES MARÉCA-GEUSES sont nettement distinctes selon cette base. L'hétérogénéité des formations et de quelques types de sols à l'intérieur de celles-ci, de même que les tendances dans les indices statistiques pour certaines séries de types ont indiqué que le classement de Jeglum et coll. (1974) sur base de la végétation donne des renseignements fiables sur la teneur du sol en agents nutritifs.
