​​​​​​​​​Tomato Fertility—Soil vs. Soilless

This presentation will help consultants and growers in Florida to understand the main differences between open field production and the use of soilless media in high tunnels or greenhouses​​. Tomato production under protective structures has been steadily increasing in the ​state (385 acres in 2015) and more rapidly around the world. Soilless media can help resolve many soilborne diseases issues and increase yield but cannot be managed the same way as an open-field/soil tomato crop would. By the end of this presentation, the practitioner should understand the principal factors affecting water and fertilizer mobilizations and retention and have a clear idea of how these interactions could affect crop quality and profitability.
