This research assessed certain specific plant-soil and community
interrelationships in eastern Oregon habitat types dominated by
subspecies of Artemisia tridentata.
The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial
grass-low shrub and low perennial grass-high shrub composition. Soil
concentrations of total nitrogen, organic...
Infiltration, soil erosion, nitrogen loss and soil profile
characteristics were measured on 36 sites representing land occupied
by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana.
Infiltration, soil erosion, and nitrogen loss were strongly correlated
but highly variable. Soil loss, but not infiltration or nitrogen
loss was significantly different between subspecies....
