Interviews

We completed in-depth interviews with a group of eight organic farmers with extensive experience using high tunnels. Participants identified six related sets of decisions that organic high tunnel users must make and for which there are few, if any, science-based recommendations:

  1. Decisions about the cropping system (crop selection, cover crops, and crop rotations)
  2. Management of the high tunnel environment through ventilation and heating
  3. Soil and nutrient management
  4. Pest and disease management
  5. Economics
  6. Attracting pollinators and beneficial insects

High Tunnel Interviews Report

Follow-Up Questionnaire

We summarized the major needs expressed by the expert panel and sent a questionnaire to the panel members. We asked them to rank the six broad topical areas in terms of importance as an area for research and to identify the three most important crops to include in the research. Respondents clarified two points:

  1. Pollinators and beneficial insects are a subset of the topic pest and disease management.
  2. Economic issues are specific to each key decision that growers make and are a major factor in assessing the biological research.

High Tunnel Follow-Up Questionnaire Report

Comprehensive Questionnaire

We developed and distributed a questionnaire to all organic vegetable growers using high tunnels in Florida and Georgia. We asked respondents to rank specific research topics on a scale of 1 (not at all important) to 5 (extremely important). The findings will direct our research objectives in future high-tunnel projects focused on improving organic vegetable production and management.

High Tunnel and Organic Vegetable Workshop

We hosted a high tunnel and organic vegetable workshop at the University of Florida in 2017.

Topics included:

  • Shading nets as a means to reduce heat stress in bell pepper
  • High tunnel organic spinach production research trial results
  • Trap crop strategies for southern green stink bug (Nezara viridula)
  • Trapping true bugs: Preliminary summary of findings for organic tomatoes in Florida
  • Conservation biological control
  • Understanding high tunnels and how they can help me
  • Organic certification and cost share program
  • High tunnel tomato cultivar trial for early spring production
  • Opportunities and challenges for high tunnel organic vegetable production in Florida
  • High tunnel organic tomato production research trial results

Grant Proposal Development

We developed and submitted a grant proposal addressing organic vegetable production in high tunnels using stakeholder input we received throughout this project.
