| ||Altai wild ryegrass is especially useful for fall and winter pasture. This grass is a long-lived perennial with a well developed root system that is somewhat rhizomatic. It can penetrate 3-4 m deep and can utilize moisture above and from a perched (high) water table at this depth. It is tolerant of cold, drought, and saline conditions. Altai wild ryegrass cures well in the field and retains most of its nutritive value throughout the summer and early fall. Because of its erect form of growth it projects above shallow snow and stays erect in deep snow, allowing the snow to bridge over the top of the leaves so that they are still readily accessible to grazing cattle.
