• Revegetation Trials on a Saltgrass Meadow

      Saltgrass (Distichlis stricta (Torr.) Rydb.) meadows may be converted to productive pasture if the low-value saltgrass is removed and productive forage plants established. Field planting trials were conducted in 1975 and 1976 to determine the effects of nitrogen fertilizer, chemical soil amendments, mulch, and furrows on establishment of crested wheatgrass (Agropyron desertorum (Fisch. ex Link) Schult.), tall wheatgrass (A. elongatum (Host) Beauv.), Russian wildrye (Elymus junceus Fisch.), and smooth brome (Bromus inermis Leyss.). In 1975, alternate-furrow planting produced thinner stands than nonfurrowed planting, but in 1976, yields of the 1975 planting were similar from both treatments. Nitrogen fertilizer did not improve stand establishment or yield. All species became established, but tall wheatgrass appeared to be least able to withstand the droughty conditions encountered in late 1975 and all of 1976. In the 1976 planting, a straw mulch increased seedling height and vigor but did not increase the number of seedlings or stand ratings. Because of its combined high seedling vigor and good drought tolerance, crested wheatgrass produced significantly better stands than did the other three species in the 1976 planting.
