Salinity Management in High Tunnel Systems

High tunnels are controlled environment structures that accelerate crop growth and protect the crop from environmental extremes. Salt accumulation in high tunnels can occur from extended use of high-salt fertilizers or composts and the absence of rainfall in the structure. High salt levels in the soil can reduce water uptake, stunt plant growth and even cause death of seedlings or susceptible mature plants. WVU Extension recommends using salt tolerance thresholds and to categorize crop sensitivity.
