    Proposal summary:

    Shearing is a necessary step in the husbandry of sheep, required
    for animal health and welfare.  Since 1994, the market price
    for wool has been dropping, now below the cost of shearing. 
    If not utilized in small batch wool niche markets, limited by
    availability of fiber mills, and with few wool buyers in NCR wool
    piles up in barns or is dumped in sink holes and woods. 
    Waste wool from farm sources is increasingly considered a
    potential fertilizer source and improves soil water holding
    capacity and quality characteristics.  Integrating animal
    and plant growing systems shows promise toward mitigating the
    impact of agriculture on climate change.  The application of
    wool has been observed to have a beneficial effect on soil
    quality and plant performance with few negative effects; yet,
    there is still much to be understood with regards to application
    rates and timing for specific crops and soils.  Field trials
    around the globe and in the Northeast and Southwest have begun to
    evaluate the effects of wool pellets and other waste wool
    products on the growth and productivity of field and vegetable
    crops; however, knowledge and application of wool pellets in the
    NCR is very limited.

    Wool Pellet Specialty Crop
    Project Overview and Timeline
    (Project Work Overview and
    Timeline, PDF)

    This demonstration and education proposal aims to apply wool
    pellets as a soil amendment in organic specialty (vegetable) crop
    growing systems.  The farmer team will explore how wool
    pellets fit with current management practices and can be used to
    meet soil nutrient requirements for organic crops.  The
    results from this on-farm implementation of wool pellets in
    growing broccoli, brussel sprouts in the field and kale in high
    tunnel production will be shared during field days, conference
    presentations, web and social media outlets and in
    publications.  Additionally, videos will be produced
    and photographs taken to facilitate sharing and learning about
    wool, pelletizing wool, application of wool pellets as a soil
    amendment and the influence of wool pellets on soil health and
    crop production.  The farmer rancher team believes that in
    order for there to be adoption of new management practices in
    farming systems that they must be applied and shared
    locally/regionally farmer-to-farmer so as to facilitate
    innovation and new management practices that can be applied on
    each unique small farm.

    Objectives: 

    1. Local integration of animal (sheep wool) and plant
      (vegetable) systems
    2. Demonstrate the potential for reducing wool waste and
      providing value added product for sheep producers
    3. Provide for enhanced soil nutrient cycling in organic
      specialty crop systems using wool pellets
    4. Evaluate and share best management practices for wool pellet
      integration with specialty crop growing systems
    5. Demonstrate production and implementation of wool pellets in
      organic specialty crop production for sheep producers and
      specialty crop growers.
