Project Information


Alaska’s Kenai Peninsula is the fastest growing agricultural area in the state. According to the
Census of Agriculture, the number of Kenai Peninsula farms increased 30% from 2007 to 2012
(compared to 11% statewide) and the number of farms selling direct to consumers increased
111% (compared to 62% statewide). The vast majority of these farms have under 5 acres in
Kenai Soil & Water commissioned a study of local market farm potential, which was completed
in early 2017 (Heuer, Melissa: Central Peninsula Agricultural Market Analysis, 2017). Farmers
who participated in the study indicated that limited volume was the primary challenge to selling
produce locally. Improvements in the distribution system, including centralized distribution, a
marketing representative, and increased coordination with potential buyers were among the
proposed solutions to the limited distribution of Kenai produced farm products. The Kenai’s
farmers are generally very optimistic about the potential for growth, if production and marketing
limitations imposed by their small size can be overcome.
The question to be researched is, “Will more efficient production using appropriately-sized
technology, along with cooperative marketing, significantly increase production and market
penetration of locally-grown root crops on the Kenai Peninsula?” At present, most farmers are
harvesting by hand with potato forks, then collecting and washing the potatoes by hand. The
heart of the project is to test appropriately-scaled equipment (single-row harvester and tubwasher)
on five small-scale farms producing root crops, to assist producers in designing a
cooperative marketing plan and to evaluate and advertise the results of both interventions.
The Kenai SWCD is well-positioned to carry out the proposed project. The mission of the Kenai
SWCD is to nurture sustainable agriculture on the Kenai Peninsula. The District encompasses
296,000 acres with a population of approximately 20,000, but this project will benefit dozens of
agricultural producers throughout the Kenai Peninsula Borough, which has a population of
57,000. In our Sustainable Agriculture program, we work with public and private partners to
identify and conserve agricultural lands, increase local knowledge and use of sustainable
agricultural practices (e.g., composting, cover cropping, riparian buffers), provide education and
equipment for small-acreage market farms and high tunnel growers, and cultivate consumer
support for an integrated local food system.

Project Objectives:

1. To trial appropriately-scaled equipment (single-row harvester and tub-washer) on
five small-scale farms producing root crops.
2 .To quantify the environmental, economic and social (labor and quality of life)
impacts of adopting new methods and equipment for harvesting and post-harvest
handling of root crops.
3. To assist participating producers in designing a cooperative marketing plan and
evaluating the results.

Materials and methods:

Baseline data for 2017 were collected from each of five participating farms via a written questionnaire developed by the principal investigator (PI) for this project.  The questionnaire (see link below) includes questions on planting, production methods, harvest and post-harvest handling, labor and sales.  Participating farmers answered a similar questionnaire in November following 2018 and 2019 harvests.  



Research results and discussion:

Aside from one farm that was already quite efficient using a 50-year-old digger, farms reported dramatic labor savings as a result of using the digger and/or washer.  The hours devoted to vine killing, digging, gathering, washing and preparation for sale were down 45 to 80%.  Digging time was reduced from days to hours. Digging time with the new digger averaged 4.5 hrs./acre with farmers reporting that efficiency increased as they gained experience.  Washing was four times faster with the drum washer.

On the downside, production did not increase as we had hoped.  This was due to in part to adverse weather conditions: unusually cold and dry weather in 2018 and severe drought in 2019.  Also, farmers were not as ready to expand acreage as they had anticipated when the project began.  Farmers said lack of adequate winter storage and difficulty obtaining seed potatoes affected their decisions regarding expanded acreage.

On the upside, the project brought about a new level of cooperation and information-sharing, a cleaning and disinfection protocol for sharing potato equipment safely, and creative ideas for cooperative marketing that may yet come to fruition.
