Biofuel Feedstocks: The Risk Of Future Invasions, Joseph M. Ditomaso, Jacob N. Barney, Allison M. Fox

All U.S. Government Documents (Utah Regional Depository)

In an effort to decrease greenhouse gas emissions, expand domestic energy production, and maintain economic growth, public and private investments are being used to pursue dedicated feedstock crops for biofuel production. Unlike food crops grown for grain-based ethanol (e.g., corn), which require high inputs of fertilizers and pesticides and typically are grown on prime agricultural land, proposed lignocellulose-based energy crops (e.g., switchgrass) typically have a neutral or negative carbon budget, require relatively few economic or environmental inputs, and can be cultivated on marginal, lower-productivity land. Thus, a rapidly growing industry related to crop selection, cultivar improvement, and conversion technilogies is …

Downward Blue Drift Of Quantum Sensors, Alec Hay, Bruce Bugbee

Techniques and Instruments

Silicon photodiodes are known to decrease more rapidly in response to blue light than to longer wavelengths (Korde and Geist, 1987). Older quantum sensors thus appear to calibrate accurately using the LI-COR 1800-02 Optical Radiation Calibrator, but may under-report radiation in the 400 – 500 nm wavelengths (blue) due to degradation of the silicon photodiode in the sensor.

Public Priorities For Rangeland Management: A Regional Survey Of Citizens In The Great Basin, Bruce Shindler, Ryan Gordon, Mark W. Brunson

Reports

Healthy sagebrush communities in the Great Basin are rapidly disappearing due to invasion of non-native plants, catastrophic wildfires, and encroachment of pinyon-juniper woodlands. Land management options, including the use of prescribed fire, mechanical thinning, and herbicides can reduce the potential for wildfire and restore healthy plant communities. Public acceptance of management actions is a critical component of developing and implementing successful long-term land management plans. This study examined citizens' opinions and perceptions about rangeland management in the Great Basin.

Greenhouse Studies On Root Growth And Morphology, Julie K. Chard

Techniques and Instruments

For studies of root growth and morphology, an ideal containerized plant culture system should provide: 1) adequate nutrients, water and oxygen; 2) appropriate mechanical impedance to root elongation; 3) adequate depth to prevent root binding; and 4) easy separation of roots from the root-zone substrate.

Columnar containers are preferable to pots because they can support deep root growth while taking up less bench space. Many columns can be arranged within a small area, such as a gas-exchange chamber, thereby maximizing the number of treatments and replications in a given space.

Standard potting substrates typically contain sphagnum peat mixed with perlite …

Gold’N Gro® 9-0-1 + 7% Zn Improves Corn Growth In Zn-Deficient Soil: A Preliminary Study, Julie K. Chard, Bruce Bugbee

Nutrients

Zinc deficiency can limit growth, especially on soils with low organic matter and high pH. Chelated Zn fertilizers maximize Zn bioavailability. We sought to determine the effectiveness of soil-applied GOLD’n GRO 9-0-1 + 7% Zn, a chelated Zn source, to reverse or prevent Zn deficiency. GOLD’n GRO was applied at 0 to 30 quarts per acre in a high pH soil. Controls included columns treated with ammonium-nitrogen at the same level as the highest GOLD’n GRO treatment. Plants treated with GOLD’n GRO had twice the dry mass, were greener, and had increased zinc levels in the plant tissue compared to …

Water-Wise Landscaping: Mulch, Heidi Kratsch

CWEL Extension Fact Sheets

Mulch can provide many benefits in water-wise landscapes. Mulch covers the soil and prevents crusting, compaction, and water evaporation. In fact, mulching around trees, shrubs, and in flower beds can result in a ten-fold reduction in evaporative water loss from soil. Reducing soil water loss means more water is available to plants and less water needs to be provided. Mulch also reduces the number of weeds in a water-wise landscape by preventing light-induced germination of weed seeds. With fewer weeds, less cultivation is required, which can prevent damage to plant roots, soil structure, and soil organisms. In addition, mulch moderates …

The 2005 Nevada Rangeland Vegetation Survey was conducted as a collaborative effort between the University of Nevada, Reno (UNR) Department of Resource Economics and the University of Nevada Cooperative Extension (UNCE) Natural Resources Program to fulfill two roles.

Western Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Richard F. Miller, Jonathan D. Bates, T. J. Svejcar, Frederick B. Pierson, L. E. Eddleman

Reports

Strong evidence indicates that western juniper has significantly expanded its range since the late 1800s by encroaching into landscapes once dominated by shrubs and herbaceous vegetation (fig. 1). Woodland expansion affects soil resources, plant community structure and composition, water, nutrient and fire cycles, forage production, wildlife habitat, and biodiversity. Goals of juniper management include an attempt to restore ecosystem function and a more balanced plant community that includes shrubs, grasses, and forbs, and to increase ecosystem resilience to disturbances. Developing a management strategy can be a difficult task due to uncertainty about how vegetation, soils, hydrologic function, and wildlife will …

Comparing Citizens' And Managers' Concerns About Sagebrush Management And Restoration In The Great Basin, Mark W. Brunson, Jennifer Peterson

Reports

The Great Basin sagebrush steppe ecosystem is among the most imperiled in the U.S. Cheatgrass invasion, conifer encroachment, and catastrophic wildfires are considered to be primary catalysts of decline. Efforts are underway to restore and increase the resiliency of this damaged ecosystem through broad-scale applications of fuel reduction and restoration treatments involving mechanical removal, prescribed fire, and herbicide application. While research points to the potential benefits of these treatments, controversy and challenge often surface when treatments are proposed on public lands. Therefore it is critical for land managers to understand the views held by key stakeholder groups concerning management and …
