Evaluation and use of a soil mineralizable nitrogen test to determine the fertilizer nitrogen needs of winter wheat grown in western Oregon

Creator:

Baloch, Dost M.

Abstract:

The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil. The objectives of this study...

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...
