Geochemical characteristics of iron-manganese nodules in seasonally-saturated soils of the Willamette Valley, Oregon

Creator:

Seter, Lisa M.

Abstract:

This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:

Abstract:

Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...
