     In Saskatchewan, Gleysolic and Chernozemic soils often are found close to each other in hummocky terrain. Magnetic susceptibility (x) is known to be reduced in poorly drained soils compared to well-drained soils, and this study investigated the use of x as an accessory criterion for identifying Gleysols. Archived soil samples from an area near Saskatoon were analyzed for x and sand content, and where necessary for organic and inorganic С and oxalate (Feo) and dithionite (Fed) extractable iron. The lowest % values were found in Humic Luvic Gleysols and the highest in Dark Brown Chernozems; Rego and Orthic Gleysols and Rego Humic Gleysols had % values that overlapped those of the Dark Brown Chernozems. Within the upper 50 cm of the profile, all Gleysols except the Rego Humic Gleysol, had at least one horizon with x less than 150 x 10~9 m3 kg"1. The x of the A and В horizons was negatively correlated to their Feo/Fed ratios, and not correlated to their sand content. The x of the deep tills was positively correlated to sand content, and not correlated to Feo/Fed ratio. It appears that x may be as useful as the Feo/Fed ratio for assisting in classifying Gleysols.
