Nitrogen available to winter wheat as influenced by previous crop in a moist xeric environment

Creator:: Qureshi, Maqsood Hassan
Abstract:: Rotating wheat with other crops is a common practice in the Willamette Valley of western Oregon. Depending upon previous crop and soil type, current N fertilizer recommendations for wheat in the Willamette Valley vary widely. Excessive fertilizer poses environmental risk, whereas lower N inputs than required by the crop represent...

Fertilizer nitrogen use efficiency by winter wheat in the Willamette Valley

Creator:: Kjelgren, Roger Keith
Abstract:: Efficiency of nitrogen fertilizer uptake by soft white winter wheat (Triticum aestivum L.) was measured over two cropping seasons across a range of soils and cropping histories in the Willamette Valley. Fate and potential losses of applied nitrogen were also assessed over a seventeen month period. In both cropping seasons,...
