In 2018, Extension personnel from the Universities of Massachusetts, Vermont, New Hampshire, and Rhode Island documented production practices and took soil and leaf samples from 20 tomato high tunnels in those 4 states, with support from the New England Vegetable and Berry Growers' Association. Soil and tissue samples were analyzed at the Universities of Maine and Massachusetts labs. Here are some guidelines for optimizing tomato production based on the data collected. NOTE - this project surveyed current practices and conditions in a variety of tunnels; additional research is needed to quantify the impact of different management and fertilization practices.
