    Agricultural waste management

    The Agricultural Waste Management program at the Twin Falls Research and Extension Center focuses on ways to cope with animal manure management on issues related to environmental quality, nutrient management and value-added products. The intent is to address the needs of stakeholders through development, evaluation and application of advanced techniques to maintain the sustainability of animal productions.

    The Extension program is designed to provide research-based educational information to clientele about waste management techniques through various publications, demonstrations and presentations.

    Current research

    Anaerobic digestion of manure, potato waste and sugar beets waste (supported by USDA and U of I)

    • Develop a bench-scale AD system to test diverse feedstocks and conduct Extension demonstrations.
    • Characterize different AD feedstocks and evaluate their biogas potential under various AD and co-AD conditions.
    • Conduct Extension activities to assist stakeholders in making better decisions regarding AD and greenhouse gas emissions.

    Mitigating odor emissions using biofilters (supported by USDA)

    • Evaluate biofilters at swine sites to demonstrate biofiltration effects on mitigating odor and gas emissions from fan exhaust air
    • Develop on-farm biofilter design manual

    Compost (supported by USDA)

    • Compost for manure management

    Dairy manure collection and land application (supported by USDA)

    • Manure management
    • Odor and gas emissions
    • Manure nutrients

    Mitigation of gas emission from manure (supported by private companies)

    • Test diverse products’ effects on gas emissions

    For more information contact Lide Chen at 208-736-3615 or lchen@uidaho.edu.

    Minor use pesticides

    University of Idaho’s Minor Use Pesticide Development program is unique in the Pacific Northwest. The State of Idaho’s concern over the lack of safe and effective agrichemicals for the protection of relatively low acreage, specialty crops in the state resulted in the creation of a U of I position for a minor use pesticide development specialist.

    The specialist must follow Good Laboratory Practices during all phases of pesticide residue testing. Residue data from these tests support petitions for pesticide registrations with the U.S. Environmental Protection Agency.
