Abstract:: Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...

Abstract:: This publication provides information on the timing and pattern of biomass accumulation and nitrogen (N) uptake for a variety of Pacific Northwest crops. You can use this information to schedule N fertilizer applications for maximum efficiency. To achieve near-maximum crop yields, an adequate supply of available N must be present...

Abstract:: Soil acidity, expressed by low soil pH, causes reduced crop growth and significant economic loss. It is the most commonly overlooked and poorly understood yield-limiting factor in western Oregon and a developing concern in eastern Oregon. This publication describes the concept of soil acidity and the limitations it causes for...
