Ammonia Volatilization from Nitrogen Fertilizers and Wastewater Reuse in the Columbia Basin

Creator:: Del Moro, Sarah K.
Abstract:: Ammonia (NH₃) volatilization and loss from nitrogen (N) fertilizer in agriculture negatively impacts crops, farm profitability, human health and surrounding ecosystems where it is deposited. A significant source of NH₃ volatilization occurs from surface application of urea on sandy soils with low pH buffering capacity such as those in the...

Enhanced efficiency nitrogen fertilizers for nitrogen management in the Columbia Basin, Oregon

Creator:: Holcomb, Jess Charles
Abstract:: 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...

Needle Sampling Dates for Nutrient Evaluation in Christmas Tree Production

Creator:: Hart, J. M., Landgren, C. G., Moody, J. T., Fletcher, R. A., and Horneck, D. A.
Abstract:: Christmas tree needle sampling to evaluate nutrient need is an established practice. Data to support the recommended fall sampling time in Oregon and Washington was not found. In addition, the recommendation for needle sampling of Fraser fir in North Carolina was made without data from winter months. The goal for...

Evaluating soil nutrients and pH by depth in situations of limited or no tillage in western Oregon

Creator:: Anderson, Nicole P., Hart, John M. (John Mervyn), 1947-, Horneck, Donald Arthur, Sullivan, Dan M. (Dan Matthew), 1954-, Christensen, Neil Walter, 1944-, Pirelli, Gene J., and Oregon State University. Extension Service
Abstract:: Many nutrients and lime are not mobile in the soil. When applied to the soil surface without tillage, these materials remain in the top 2 inches, especially in production systems that lack tillage. If a soil sample is taken at a standard 8-inch depth, the top 1 to 2 inches,...

Soil acidity in Oregon : understanding and using concepts for crop production

Creator:: Hart, John M. (John Mervyn), 1949-, Sullivan, Dan M. (Dan Matthew), 1954-, Anderson, Nicole P., Hulting, Andrew Gerald, Horneck, Donald Arthur, Christensen, Neil Walter, 1944-, and Oregon State University. Extension Service
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...
