Abstract:: Potato (Solanum tuberosum L.) is among one of the largest and most important staple food crops in the world. One of the most productive growing potato regions is the USA is the Oregon and Washington Columbia Basin. Both states produce approximately 26% of the USA potatoes in the market. In...

Abstract:: Puerto Rico’s climate varies greatly even if it is categorized as a tropical climate. On some parts of the island, there are desert like conditions where rainfall averages 36 inches a year unlike the western side or the central part of the island where rainfall averages 200 inches.1 Heavy rains...

Creator:: Marks, Jade A.
Abstract:: Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Creator:: Hynicka, Justin D.
Abstract:: Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...

Creator:: Cappellazzi, Jed E.
Abstract:: Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...
