Terroir Studies In Washington And Wisconsin American Viticultural Areas, Snejana Karakis
Theses and Dissertations
The concept of terroir has been evaluated since the 12th century, when Cistercian monks from Burgundy realized that the physical environment in which grapes are grown has a major influence on the character and quality of the resulting wine. These environmental conditions affecting grape and wine quality are known as terroir in viticulture and have become increasingly important in the grape growing and wine industry. In this dissertation, three studies investigating the terroir of vineyards located in Washington and Wisconsin American Viticultural Areas (AVAs), which are defined by the Alcohol and Tobacco Tax and Trade Bureau (TTB) as delimited grape-growing …

Determining Sources Of Nitrate In The Semi-Arid Rio Grande Using Nitrogen And Oxygen Isotopes, Diego Alberto Sanchez Hernandez
Masters Theses
The Rio Grande, a semi-arid river in the American Southwest, is a major source of surface water for agriculture and drinking supplies in New Mexico and Texas. In addition to increasing salinity, considerable increases of NO3- [nitrate] have been observed in the semi-arid portion of the Rio Grande. It is possible that elevated water salinity inhibits denitrification on irrigated fields and, thus, fails to mediate excess nutrient load from anthropogenic activities. Therefore, two major goals of this project were to 1) characterize and quantify major NO3- sources, and 2) assess whether elevated water salinity affects microbial …
