Introduction, prepared by ST

Intent: To extend the growing season of leafy greens, lettuce, and root crops to serve our existing outlets such as Hopewell Farmers Market, Nomad Pizza, and Zone 7.
• Capital Investment; North Slope Farm
• Daily management; RCM and ST
• Site Details; infrastructure and fields managed by North Slope Farm
o 6 outdoor low tunnels 5’ W X 40’ L
o 2 unheated green houses
Farmhouse Gothic; 28’ X 84’ w/ 4 beds @ 48” wide
Ralph’s House; 27’ X 76’ w/ 4 beds @ 48” wide
o 1 heated Greenhouse for table top production
• Outdoor low tunnels will cover crops such as tatsoi, spinach, and arugula. Two cuttings are expected for harvest. The hoops are constructed of 3/8” X 12’ rebar covered in recycled drip tube. The outer skin is 6 mil plastic that is 13’ W X 50’ W. A layer of remay may be added to the interior for extra warmth and reduced temperature fluctuation.
• One hoop house will be used for direct seeded crops such as spinach, arugula, tatsoi, and salad mix. The other hoop house will be used for transplanted crops such as kale, scallions, leeks, swiss chard, fennel, and beets. Carrots and radishes have been direct seeded into one open bed early, as the other beds are currently occupied by late planted tomatoes.
• .The heated greenhouse will be used for table top production of salad mix. Potted herbs such as parsley and basil will also be grown.
• Regular records will be kept of costs and production. Worker hours and market income will be tracked. The materials purchased should be able to be reused, improving profit margins in future seasons.
o $385.60 for seed costs
o $370 for plastic and remey over three years
o $90.80 for rebar and sand over ten years
o $108 for plastic sandbags over three year
Total $954.40 for one year
• Workers will have to be mindful of temperature to open and close the low tunnels or remove remey in the hoop houses. The difficulty of winter weather will be a challenge in harvesting, handling, and marketing. Costs will be calculated against profit to see if this is a viable operation for North Slope Farm.
• The inspiration for winter production at North Slope Farm came from a lecture at the NOFA summer conference. A Connecticut grower, in zone 3, presented a low tech option of covering field crops to produce a nutritious and profitable product for his customers during the winter time. This inspired me to keep producing local organic food through the winter. I hope that having a consistent presence through the winter will support existing customers and win over new customers. Winter production also keeps workers on the farm and in constant dialogue with agriculture. Some challenges we have already faced have been 30mph winds blowing off our outdoor low tunnels. Did we cut the plastic too short? Are the sandbags not filled enough? Do the tunnels need to be smaller? At what temperature should we open and close the tunnels? These are questions that have already risen and in the middle of the winter I am sure there will be many more. To supply fresh local organic food is the main goal and we will need support from our community to make it a reality.
