The phosphorus dilemma

Creator:: Iida, Chelsey L., Shock, Clinton C., and Oregon State University. Extension Service
Abstract:: Phosphorus is an essential building block for all forms of life, from plants to animals, including humans. Because phosphorus is closely tied to land productivity and plant growth, many homeowners apply phosphorus fertilizers liberally to lawns, while growers add them to cropland. However, in certain environments, too much phosphorus can...

Using nitrogen fertilizers wisely

Creator:: Andrews, Gail Glick and Oregon State University. Extension Service
Abstract:: Plants need nitrogen to grow. However, if there is more nitrogen (in the form of nitrate) in the soil than plants need, some of it may leach below the rooting zone and end up in the groundwater that supplies your drinking water.

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...

Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

Creator:: Pérez, Angela L.
Abstract:: Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

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...
