Scenic valley farms research and development, 2015

  1. 1. SVF 2015 Research & Development
  2. 2. • SWD management using high tunnel • Vertical growing produce in tunnels • Solar thermal high tunnels • Vermicomposting using tunnels (future) Overview
  3. 3. • Designs and manages high tunnels, climate control systems, and solar thermal heating technology • Twelve high tunnels in Minnesota and Wisconsin, sizes - 30x64, 30x72, and 30x96 • Produces USDA organically certified tomatoes, peppers, blackberries, raspberries, strawberries, cucumbers, green garlic, eggplant, herbs, leafy green produce and ginger (new 2015) • Decades of agriculture and engineering experience Scenic Valley Farms
  4. 4. SWD management using high tunnel • 2 year SARE Grant to research management of Spotted Wing Drosophila using high tunnels • In 2014 3rd year for SWD at SVF on blackberries and strawberries • In 2014 research was limited due to brutal winter on blackberries • Installed insect netting on side walls, doors, and end walls • Insect netting bought from http://www.duboisag.com/en/proteknet-insect-netting.html – 6’6” x328’-80gr - $335, maybe local supplier • Insect netting restricts air flow by 20% • Traps – cedar cider vinegar, liquid dish soap or sugar water & yeast • Set two traps inside and two outside tunnels • Install on Bumble Bee hive in each tunnel
  5. 5. SWD management using high tunnel (con’t) • Install netting by July • Check traps once per week starting in July
  6. 6. SWD management using high tunnel (con’t) Results: • Noticed SWD inside traps mid July • Rosemount blackberry tunnel – No SWD entire season • Readstown blackberry tunnel – some SWD, came in thru door • Readstown strawberry tunnel –unintentionally let in SWD thru door. Proceeded to pick all ripe berries, applied Pyganic for three consecutive days, then two applications of Entrust seven days apart – in two weeks eradicate SWD • Outside strawberry bed infected – picked clean, row cover hoops with netting attached using clothes pins, sprayed Pyganic, Entrust through netting. No sign of SWD after two weeks • Pollinators? • SWD on culled tomatoes - yes • Insect netting repair? • 3M
  7. 7. Vertical growing produce in tunnels Grown in dirt not hydroponically using 6” x 5’ PVC pipe or stacked pots Increase production Strawberries – 12K plants per 30x96 at 1/2# per plant- 8x the plants vs bedded plants Lettuce and herbs – 3x more plants vs bedded plants year 1 – day neutral strawberries in PVC pipe - not very good yields, does not over winter year 2 – day neutral strawberries, lettuce, herbs in PVC pipe, day neutral strawberries in 4 and 8 sided pots year 3 – day neutral strawberries in 8 sided pots (goal ½# per plant), herbs and lettuce in PVC pipes for commercial sale
  8. 8. Solar Thermal high tunnels
  9. 9. Vermicomposting using tunnels (future) • SVF uses 150 cu yards of horse compost per year • Hard to get • Commercially produce composts in these quantities cost prohibited • Design and develop a vermicompost system to replace some of the horse compost • Used farm’s pruned plant material and culled produce • Use food waste from other sources • Use high tunnel to pre-compost (hot compost) inputs • Design a system that is available to other growers
