Accomplishments
Accomplishments
- Short-term Outcomes: Quantitative, measurable benefits of the research outputs as experienced by those who receive them. (i.e. dollars saved, reduction in disease incidence, increase in ADG)
- WERA 1014 members from Oregon and Washington partnered with the Oregon Forage and Grassland Council to host the Resilient Pasture & Forage Symposium in October 2025 to increase knowledge and producer compacity around irrigated and intensively managed pasture systems. A field tour, speakers, and a farmer panel engaged more than 135 attendees. Afterward, nearly all survey respondents (94%) reported learning something useful for their farm or work with many attendees commenting on gaining knowledge on the importance of protecting pasture root growth, the benefits of deep-rooted plants like plantain, chicory, and alfalfa, and optimizing grazing management techniques, but many attendees also commented on the human aspects of resilience. One attendee reported, “Kudos to the organizers of the Symposium. The focus on resilience for the farmers/ranchers, as well as for the land, was useful—it's easy to think I'm the only one struggling with failure and discouragement” and another wrote, “Really, I learned so much technically but more so, I learned that resilience begins with the farmer and to hear their stories helped me find more patience with my own setbacks.”

- Milestones: Key intermediate achievements linked to the project.
- Pasture Calendar (Co-PD) for train the trainer for NRCS and others who work with producers on pastures. 2024 National Agricultural County Agents Association – Western Region Publications Award
- In Idaho, agronomists and researchers are placing greater emphasis on advancing management practices in dairy forage production systems to enhance on-farm productivity, promote soil health, safeguard water quality, improve resilience to weather extremes, and support long-term food system sustainability. As such, some of the research initiatives include cover cropping in silage corn systems, phosphorus drawdown using winter forages, and alternative forages performance trials, among others.
- Grower benefit from the knowledge and adjustment of their resource input, reducing resource wastage and ecological pollution for fertilizer run-off and leaching in sudangrass production
- Knowledge increase for growers/pest control advisors regarding insect control products and related efficacy comparisons in alfalfa
- Granulate Cutworm Insecticide Efficacy – Pyrethroid class insecticides did not provide as much early reduction potential new insecticides (active ingredient = Isocyloseram)
- Alfalfa regrowth was not correlated with granulate cutworm numbers, as only active ingredient that result in alfalfa regrowth at 7 days post treatment was chlorotraniliprole (active ingredient in both Besiege and Vantacor)
- Currently (and apparently very outdated) treatment threshold for treating granulate cutworm is not applicable. Current research indicates it should be less than 1.0/sq. foot following bale removal.
- Alfalfa weevil numbers were higher in pyrethroid insecticide treated plots than in untreated plots, thought due to reduction of ladybird beetles by the pyrethroid insecticide application.
- Insecticide data indicated that insecticide resistance to pyrethroid insecticides existed at site in spite of no known previous applications.
- Steward efficacy for alfalfa weevil control is declining (lower than in previous years).
- Designed and implemented replicated field experiments integrating agronomy, entomology, soil science, and livestock systems.

- Delivered statewide Extension programming and direct producer consultation.
- Coordinated wildfire and drought resource dissemination.
Impacts
- WA State Alfalfa Variety Trials An economic analysis of adopting the top three varieties compared to using the average variety in the trial showed a net increase of $77 acre-1 year-1, resulting in a measured potential impact of 19 million dollars a year-1.
- Reducing Nitrate Toxicity Risk in Montana Forage Systems Research identifying sulfur fertilization strategies to reduce nitrate accumulation provides producers with actionable tools to improve livestock safety and forage value, particularly during drought conditions. Extension dissemination through workshops, radio interviews, and publications strengthened producer capacity to mitigate toxicity risk while maintaining yield
- Improving Alfalfa Weevil Management Multi-state collaboration evaluating insecticide efficacy and persistence generated updated early-season management recommendations. These findings support economically efficient pest control decisions and reduce unnecessary insecticide applications
- Integrating Soil Health with Livestock Production Research on dung beetles, parasite management, and perennial forage systems contributes to improved nutrient cycling, soil biological activity, and long-term rangeland resilience
- Enhancing Drought Resilience Regional Extension programming and individualized consultations equipped producers with science-based strategies to adjust seeding decisions, grazing timing, and fertility management under moisture-limited conditions
- My research focuses on the role of phytochemicals in pasture forbs and their effects on animal performance, health, nitrogen use, and greenhouse gas emissions in pasture-based livestock systems. Working with a multidisciplinary team, my lab evaluates phytochemicals at the varietal level and designs diversified pastures to enhance milk yield, feed intake, environmental performance, and economic sustainability. Supported by a USDA Western SARE Research and Education grant, we conduct both on-station and on-farm trials to assess pasture phytochemicals and ecosystem services, including soil health and pollinator support. I also led the first multi-year sheep grazing studies within an agrivoltaics system, generating foundational data on the compatibility of solar infrastructure with pasture-based livestock production and informing land-use and policy discussions. In addition, I have conducted pioneering research on industrial hemp byproducts, including one of the first spent hemp biomass feeding trials, providing regulatory-relevant data for the livestock and hemp industries. More recently, I evaluated chicory root as a functional supplement to reduce parasite loads in grazing livestock
