Organic Production in High Tunnels

Abstract

High Tunnels have several production characteristics that make them ideal for organic growing of vegetables and fruits. Plants grown in high tunnels are protected from rain, and constant wet foliage caused by dew, which often is the major cause of serious disease problems. Daily water needs are supplied by drip irrigation, which can prevent erratic soil moisture conditions, which are often the cause of fruit cracking. Plants are protected from high winds, which can cause micro bruises of the plant tissue and allow disease organisms to invade the plants. Since high tunnels supply plants with ideal growing conditions as compared to outside production, much of the overall stress is eliminated. Because of the increase in both growing days and heat units, producers have an excellent opportunity to use cover crops and methods to help comply with different organic recommendations and requirements.
