Home Water Self-Check: Do-It-Yourself Water Check For The Home Landscape, Todd A. Mccammon

All Current Publications

In Utah, nearly two-thirds of the water consumed by residential homeowners is used to maintain landscapes. Recent water checks conducted by Utah State University Extension found that a typical homeowner applies 80 inches of water each growing season. This is twice as much as is needed.

Some Environmental Relationships Of Undergrowth Species In Aspen Communities Of The Intermountain West, W F. Mueggler

Aspen Bibliography

This analysis results from an opportunity to explore plant-environmental relationships from data collected for a different purpose. Origin of the data is a study designed to develop an aspen community-type classification for southern Idaho, western Wyoming, Utah, and Nevada which resulted in the publication "Aspen Community Types of the Intermountain Region" GTR INT-250 by W.F. Mueggler (1988).

Measurement Of Water Stress: Comparison Of Reflectance At 970 And 1450 Nm, Daniel Dallon

Water Stress

Nitrogen stress in crops has been measured for many years using inexpensive spectrometers with ranges up to 1000 nm. Detectors for spectral measurements above 1000 nm are expensive, but they can be used to analyze water stress in plants by measuring reflectance of the major water bands at 1450 nm and 1900 nm. Although there is a water band at 970 nm, it is generally considered to be too small and inconsistent to use as an indicator of water stress. This experiment aims to determine the correlation between reflectance at 970 nm and 1450 nm. This was done by taking …

Comparison Of The Analytical Spectral Devices Fieldspec Pro Jr And The Apogee/Stellarnet Model Spec-Par/Nir Spectroradiometers, Daniel Dallon

Techniques and Instruments

Spectroradiometers can be used to identify plant stress by measuring crop reflectance. Spectroradiometers can measure nitrogen and water stress, and subsequent adjustments in applications can improve crop yield and reduce over-application. Two portable spectroradiometers and their accompanying software were compared for accuracy and ease of use while conducting experiments to determine water and nitrogen stress in crested wheat grass and soybean plants. The first unit was a higher priced ($40,000) visible/NIR triple diodespectroradiometer (ASD FieldSpec Pro JR) with a range of 350-2500 nm. It uses ASD’sFieldSpec Pro RS3 software. The second was a low-priced ($3600) visible/NIR fixed diode spectroradiometer (Apogee/StellarNet …

Water Wise Plants For Utah Landscapes, Wade Bitner, Rick Heflebower, Larry Sagers

All Current Publications

In order to better market the water wise plants available in many Utah nurseries and garden centers, and to assist consumers in identifying these plants, a program to recognize desirable low water use species has been developed.

Class I Integrons And Sxt Elements In El Tor Strains Isolated Before And After 1992 Vibrio Cholerae O139 Outbreak, Calcutta, India, Amita Kaundal, S. Roy Chowdhury, M. Thungapathra, Thandavarayan Ramamurthy, Gopinath Balakrish Nair, Amit Gosh

Plants, Soils, and Climate Faculty Publications

We examined the distribution of class I integrons and SXT elements in Vibrio cholerae O1 El Tor strains, isolated in Calcutta, India, before and after the V. cholerae O139 outbreak in 1992. Class I integrons, with aadA1 gene cassette, were detected primarily in the pre-O139 strains; the SXT element was found mainly in the post-O139 strains.

Selective Filters Increase Response Of Silicon Diode Spectroradiometers Above 700 Nm., Dan Dallon, Glen Ritchie, Bruce Bugbee

Fact Sheets

Three layers of the “cosmetic burgundy” filter extended the accuracy of the spectrum from 800 to 920 nm.

Three filter layers may decrease the accuracy below 700 nm.

Trichloroethylene In Edible Fruit Growing Above Shallow Groundwater Plumes: Field Survey Results, Bill Doucette, Julie K. Chard, Brandon Chard, Coreen Crouch, Bruce Bugbee, K. Gorder

Phytoremediation

Potential factors impacting tree and fruit concentrations include the above ground variables of tree type, tree age/size, irrigation patterns, time of season and number of fruit and the below ground variables of TCE groundwater concentration, depth to groundwater, TCE soil and soil gas concentration, soil type and fraction of groundwater used.

Use Of Ground-Based Canopy Reflectance To Determine Radiation Capture, Nitrogen And Water Status, And Final Yield In Wheat, Glen L. Ritchie

Publications

Ground-based spectral imaging devices offer an important supplement to satellite imagery. Hand-held, ground-based sensors allow rapid, inexpensive measurements that are not affected by the earth’s atmosphere. They also provide a basis for high altitude spectral indices. We quantified the spectral reflectance characteristics of hard red spring wheat (Triticum aestivum cv. Westbred 936) in research plots subjected to either nitrogen or water stress in a two year study. Both types of stress reduced ground cover, which was evaluated by digital photography and compared with ten spectral reflectance indices. On plots with a similar soil background, simple indices such as the normalized …
