The Great Groups of the Luvisolic Order

Only one great group of the Luvisolic soils occurs in Saskatchewan. Soils of the Gray Great Group have a Bt horizon and lack an Ah horizon. In the undisturbed state the Bt horizon is overlain by an grayish, sandy or silty Ae horizon. Transitional soils with features of both grasslands and forests can be classified as Dark Gray Chernozems or Dark Gray Luvisols; see the Soil Classification section for more information on these soils.
