  • Vegetables: tomatoes


  • Crop Production: fertigation, organic fertilizers
  • Production Systems: general crop production

    Proposal summary:

    Many farmers are growing organic greenhouse tomatoes, but using organic fertilizers in a drip irrigation system has proved problematic. This project will test adaptations to a drip irrigation system and fertilizer dilutions to overcome this problem. The size of the tomato plants will be measured, and yield and quality data of the fruit will be collected and analyzed. Outreach will be through a grower field day, an article, and grower presentations.
