Investigating The Impact Of Restricted Irrigation Practices On Soil Moisture Variability And Distribution In A Dry Farmed Vineyard Site, Boise, Idaho, J. Duffin, David Wilkins, J. Guenther Dec 2011

Investigating The Impact Of Restricted Irrigation Practices On Soil Moisture Variability And Distribution In A Dry Farmed Vineyard Site, Boise, Idaho, J. Duffin, David Wilkins, J. Guenther

Changing climate in semiarid regions may result in increased water stresses for agricultural production as timing and form of precipitation may result in diminished surface water for irrigation. To prepare for these changing conditions, studies are being conducted on the possibility of dry farmed agriculture as an alternative to irrigated production. This study specifically investigates the ability to grow productive wine grapes with limited or zero irrigation in the Boise Front Foothills, West Foothills TIC Vineyard, located in a climate zone receiving less than 300 mm of annual precipitation. Traditional vineyard performance factors such as planting densities, soil type, rootstock, …

Opportunities for field experiences are often presented as a primary reason that undergraduate students gravitate towards geosciences as a major field of study. What those students may not understand is that, for professional geoscientists, field experiences go beyond the freshman-level field trip, and students may overlook the processes of observation, data collection and analysis that are inherent to the science. The Department of Geosciences at Boise State has developed a set of sophomore field experience courses designed to "set the hook" into new majors and prepare them for field experiences in upper division coursework. These sophomore courses have been shown …

With funding from the National Science Foundation’s Graduate STEM Fellows in K-12 Education program (GK-12), students from Boise State University’s graduate programs in biology and geosciences gain experience in curriculum development and delivery in a wide range of settings. The project uniquely partners graduate students with educators at three informal science centers that use their settings to focus on science and environmental issues of local, regional, and global importance. Two-three graduate students per year (GK-12 Fellows) are placed at each learning center where they work to create, modify, and deliver learning activities that incorporate local and regional themes as well …

Beginning in 1971 with the first plantings of wine grapes, the wine and wine grape industry in southwest Idaho have grown to become significant contributors to the state economy with an annual impact of $75 million (Bierle et al., 2008). With around 1600 acres under cultivation in 50 vineyards producing at least 24 varietals (as of 2007), wine grapes are the state's second largest fruit crop in acreage, with the majority of the crop (USDA, 2008) being produced in the western Snake River Plain of southwestern Idaho and eastern Oregon. In April, 2007, a 21,400 sq. km area in this …
