How is salt injury confirmed?

• A. Soil conductivity test (solu-bridge)
• B. IR spectral analysis
• C. Chlorophyll fluorescence
• D. Soil temperature measurement

Answer: (A)

Salt injury shows up when soluble salts in the root zone are high enough to hinder water uptake and harm the plant. The most direct way to confirm this is by measuring soil salinity, which is done with a field soil conductivity test like a solu-bridge. A reading that exceeds the turf or ornamental species’ tolerance indicates salt injury is present. Other methods don’t pinpoint salinity as the cause: IR spectral analysis isn’t a practical field diagnostic for root-zone salinity; chlorophyll fluorescence reveals stress in general but doesn’t identify salinity as the culprit; soil temperature measurements don’t reflect salt levels in the soil.
