Kimberly & Anna at Open View Farm

The farm fiber field that includes wool, milkweed, hemp and flax is a growth area  as farmers and researchers look for better substitutes for fossil-fuel-based, non-renewable fabrics and building materials.  There's an exciting opportunity to find solutions that support farmers while also addressing both the climate crisis and the micro-plastic crisis affecting all life on earth.

Here in Vermont, from 2007 to 2012 the number of sheep farms increased 27%, and the number of sheep increased by 35%.  However, for a variety of reasons, many sheep farmers have struggled to turn a profit. At the same time, growing interest in natural non-toxic materials for multiple purposes, including insulation, upholstery and other home and garden uses, could provide a market for raw wool that is as much a part of sheep farming as are meat and milk.  A number of these items are already produced in Europe and in the western United States.

Wool

Grazing Sheep

Sheep must be sheared regularly in order to remain healthy, but there is not a ready market for the wool that is collected. This has meant that farmers often store bags and bags of the wool in their barns, accumulating a product that doesn't have a place to go.

Kimberly Hagen of the Center's Pasture Program (and herself a long-time sheep farmer) became aware that in other places, including Europe and the western US, enterprising farmers and interested partners in the building trades were turning wool into building insulation. Suzy Hodgson, the Center's Sustainable Agriculture Outreach Specialist, also saw the intrinsic properties of Vermont wool as a possible energy efficient and renewable home material.

In fall 2016, with funding from a USDA Rural Development grant in place and support from the Vermont Agency of Agriculture, Food and Markets, the team announced a one-year feasibility study with the purpose of learning whether this is a possible fit for the needs of Vermont's shepherds and its green building trade. The project started in January, 2017 and concluded in 2019 with community presentations about the development of Vermont wool pellets as a soil amendment.

Here in 2020, we are planning the next phases of the project, which - with funding - will include both an in-depth research on how the pellets affect productivity, water, and soil chemistry and structure, and also a pilot to determine the actual costs and requirements of at-scale production of the pellets using Vermont wool.  (Visit here if you're interested in supporting this exciting work.)

 

Wool Project Findings & Reports

Findings were extremely exciting to both vegetable farmers and livestock producers, with promising implications for water quality and soil health as well.  With funding, the work will continue in 2020 with in-depth field trials with different vegetables and also an at-scale test of the production of pellets from wool from the region.

Milkweed

Center for Sustainable Ag. personnel, along with other UVM Extension colleagues, have been exploring the potential for milkweed as a commercial crop that also provides well-documented ecosystem services.

In 2019, Suzy Hodgson, along with VT-NRCS partners, investigated and PDF iconshared findings about potential income and other benefits from milkweed as a crop
