Abstract

In this study we report on soil nutrient levels and soil quality in 35 high tunnels on 29 Maine farms. The objective of the research was to determine soil fertility and soil health status; to identify trends in high tunnel soil nutrition management; and to identify grower practices needing additional or continued education with high tunnel farmers. Regardless of tunnel age, more careful management of pH, soluble salts, nitrate, and phosphorus are recommended in order to avoid deficiencies and excesses. This includes using less compost and more high-nitrogen fertilizer materials. Minimizing tillage and ensuring adequate moisture through improved irrigation practices are also recommended.
