Low levels of fall applied ammonium sulphate nitrogen and treble super-phosphate phosphorus fertilization were effective to increase production, crude protein, and phosphorus content of forage on high elevation native ranges in southwestern Utah. Vegetation was dominated by bistort, western yarrow, bluegrass, tufted hairgrass, spike trisetum, alpine timothy, and letterman needlegrass. The most effective level appeared to be 60 lb. each of available nitrogen and phosphorus in combination. Fertilizers were applied once and the residual effects carried over for two growing seasons for production, three for phosphorus, and one growing season for crude protein and gross energy. Visual differences between treatments were obvious during the first two years.
