Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching,
and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...

This study examines the impact of the recently constructed
limited- access highway, Interstate 5, on agricultural land in Linn
County, Oregon. More specifically it scrutinizes the quality and
quantity of the land relinquished to the highway right -of -way; the
effects on field boundaries, connectivity, mobility, drainage, land
use, miscellaneous...

Soil organic matter (SOM) is the result of the balance between decomposition and incorporation of detritus from both above and below ground sources into the soil. It composes only a fraction of the soil by mass but it is one of the most critical components. The Detritus Input and Removal...

This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...
The 13th Annual Northwest Traffic Engineering Conference and the 1960 Annual Northwest Road Building Conference this year have been combined to give a broader concept of the field of highway engineering to persons interested in both phases. Future conferences will alternate as before between the States of Washington and Oregon....
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
