Nitrogen mineralization from organic amendments during the second year following application

Creator:: Kusonwiriyawong, Charirat
Abstract:: Estimates of nitrogen (N) available from long-term application of organic amendments are required to balance N inputs with crop N requirements. Two studies were conducted to (1) determine N mineralized from organic amendments (manures and composts) during year 2 after application, and (2) compare plant-available N (PAN) determined via in...

Estimating plant-available nitrogen release from manures, composts, and crop residues

Creator:: Gale, Eric S.
Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...

Lead toxicity at various dosages in Naeemi lambs in Kuwait

Creator:: AL Sabbagh, Tariq Ashour
Abstract:: Environmental contamination along roadways with lead from processed petroleum and automotive residues has been reported. Toxicity to the herbivores grazing these areas has not been well studied. Comparison of lead concentrations adjacent to roads in Kuwait and in Oregon, USA was studied. Soil samples were taken from three sites at...

Biotransformation of 2,4,6-trinitrotoluene by ruminal organisms

Creator:: De Lorme, Marthah J. M.
Abstract:: 2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

Metabolism of toxic plant alkaloids in livestock : comparative studies on the hepatic metabolism of pyrrolizidine alkaloids in sheep and cattle and of ergot alkaloids in an endophyte-resistant mouse model

Creator:: Duringer, Jennifer Marie
Abstract:: The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...

Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...

Enzyme-Linked Immunosorbent Assay (ELISA) of Vitellogenin in Temperate Basses (Genus Morone): Plasma and In Vitro Analyses

Creator:: Heppell, Scott A., Jackson, Leslie F., Weber, Gregory, M., and Sullivan, Craig, V.
Abstract:: Blood levels of the egg yolk precursor vi- tellogenin (VTG) can be used as a deﬁnitive marker for the onset and progress of maturation in female teleosts. In the present study, an enzyme-linked immunosorbent assay (ELISA) was developed to measure VTG in blood plasma from three species of temperate basses....

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...
