Native tree shows potential for Utah's high desert region

Researchers in Utah selected superior accessions of native bigtooth maple (Acer grandidentatum) trees using aerial digital images taken during peak fall color. Trees were physically located using GPS technology then visually evaluated for initial selection; six trees were selected for propagation. Experiments showed that the optimum time for chip budding scions of wild accessions in northern Utah is July through mid-August, and that opportunity exists for successful budding of wild bigtooth maples in the region.

Owning an in-ground irrigation system shown to affect residential lawn watering behaviors

To Water or Not to WaterA study compared lawn irrigation perceptions, knowledge, and behaviors of homeowners with and without in-ground sprinkler systems (IGS and NIGS, respectively). Homeowners with IGS watered more frequently than NIGS; 67% to 90% of IGS and 19% to 31% of NIGS homeowners watered two to three times per week or more. The authors recommend educational efforts for all homeowners to help conserve water and protect water quality, adding that efforts should concentrate more on IGS homeowners.

CT Systems Promising for Central Valley Tomato Industry

Conservation Tillage Systems Contribute to California's Flourishing Tomato ProductionTwelve years of research yielded a report on advances in conservation tillage (CT) systems for tomato processing in California's Central Valley and documented the history of technological developments in the region. The report includes pertinent information on opportunities and barriers for further adoption of CT for tomatoes. The authors project that if yield performance and bottom-line profitability can be maintained, CT systems will become increasingly popular among tomato producers in the Central Valley region.

New plant palate possible with irrigation systems

Irrigation Key to Plant Diversity, Survival on Green RoofsNineteen species and cultivars of succulents, grasses, and forbs were evaluated under seasonal irrigated and non-irrigated conditions on experimental green roofs in Alabama. Only succulents like stonecrops survived without irrigation. The experiments showed that irrigated experimental green roofs had significantly lower summer substrate temperatures, and many plants survived both winter and summer under irrigated conditions. The study recommends irrigation for extensive green roofs to increase plant options.
