Investigating the Potential of Slow Release Nitrogen Fertilizer to Increase Agricultural Nitrogen Management Efficiency for Tall Fescue in the Southern Willamette Valley

Creator:

Derksen, Jacob Z.

Abstract:

Nitrogen (N) fertilizer application can promote nitrate leaching below the rooting zone and into groundwater drinking water sources in many agricultural settings. The proper management of N application can minimize non-point source nitrate pollution to groundwater. This study examines the potential for enhanced efficiency fertilizers, specifically urea treated with a...

Incorporation of salmon derived nutrients into Oregon coastal streams and the role of physical habitat

Creator:

Shaff, Courtney D.

Abstract:

Stream restoration techniques in western Oregon and Washington include physical habitat restoration and more recently the addition of salmon carcasses to improve food availability for juvenile fish. Although both are common practices, few studies have examined the effects of carcass placement and the interaction of nutrient enrichment with physical habitat...
