High Tunnel Pollinators, Miranda L. Jones, Sheriden Hansen, Kelsey Graham, Robert Nelson Schaeffer, Brent Black Sep 2026

High Tunnel Pollinators, Miranda L. Jones, Sheriden Hansen, Kelsey Graham, Robert Nelson Schaeffer, Brent Black

All Current Publications

High tunnels are used to extend the growing season. Unlike greenhouses, high tunnels are semi-permanent and not heated or cooled by a climate-control system. Instead, they use plastic sheeting to trap solar heat, allowing for season extension in temperate climates around spring and fall. Bee pollination can improve yields for several valuable crop species grown in high tunnels. Because high tunnels are largely enclosed, bees are typically released and managed within the structure. This fact sheet provides information on how to obtain and manage bee pollinators in high tunnels.

Training Turfgrass For Drought Resilience, Kelly Kopp, Jerry L. Goodspeed Apr 2026

Training Turfgrass For Drought Resilience, Kelly Kopp, Jerry L. Goodspeed

All Current Publications

Utah’s semi-arid climate always makes efficient irrigation essential, but never more so than during a drought. In many communities, outdoor landscape irrigation represents the largest share of residential water use during the summer months. At the same time, research and Utah State University (USU) Extension observations have consistently shown that lawns across the state are often overwatered, leading to shallow root systems and increased vulnerability to heat and drought stress. Adjusting irrigation practices during drought not only conserves water but also improves the long-term health and resilience of turfgrass systems.

Morphological And Physiological Responses Of Cymbopogon Citratus And Pennisetum Alopecuroides To Saline Water Irrigation, Haifeng Xing, Asmita Paudel, Julie Hershkowitz, Youping Sun

Plants, Soils, and Climate Faculty Publications

Reclaimed water provides a sustainable and economical alternative for landscape irrigation, but its elevated salinity can negatively impact sensitive plant species. This study evaluated the salinity tolerance of two widely used ornamental grasses, Cymbopogon citratus (lemon grass) and Pennisetum alopecuroides (fountain grass), under three electrical conductivity (EC) levels: 1.2 (control), 5.0, and 10.0 dS·m−1. Visual assessments over 62 days showed that both species maintained an acceptable appearance under saline conditions. C. citratus exhibited no foliar damage, with visual scores above 4.6 even at 10.0 dS·m−1, whereas P. alopecuroides showed slight leaf injury but retained a score …
