Doescher, Paul Steven

Abstract:

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...
