Summary Physical and chemical analyses of five geographically associated Solonetzic and Chernozemic Black soil profiles from the glacial Lake Edmonton basin were conducted to investigate the mechanisms operative in their genesis. Soils, classified as Black Solonetz and Black Solodized Solonetz, satisfied both morphological and chemical criteria as set forth by the National Soil Survey Committee of Canada for soils of the Solonetzic Order. The lack of pronounced solodization in the Bnt horizons of these soils was attributable to the proximity of bedrock to the surface which prevented the removal of Na salts from the profile. A high content of exchangeable Na in the Bnt horizons appeared to have assisted the comminution of coarse clay particles to fine clay particles. The soil, classified as Saline Black, had the chemical properties but lacked the morphology of Solonetzic soils. Two Eluviated Black profiles were genetically different from each other. While the Eluviated Black profile in one case was completely solodized and appeared to be regrading towards the normal soil type, the soil at the other site had features that reflected the influence of weak solonetzic processes.
