AbstractA glasshouse study was conducted to determine how nonfertilized and fertilized soils collected in creosotebush [Larrea tridentata (DC.) Cov.] communities would influence seedling leaf growth and shoot production of Lehmann lovegrass (Eragrostis lehmanniana Nees) and blue panicgrass (Panicum antidotale Ritz.). Soils were collected at 3 locations around creosotebush plants: (1) at the crown base (Basal), (2) along the outer canopy edge (Drip), and (3) in areas between plants (Open). Leaf lengths and shoot production were greatest on nonfertilized soils collected at the plant base, intermediate at the canopy edge, and least in open areas. Leaf lengths and shoot production significantly increased on fertilized soils collected in open areas.
