DEATH OF WOODY ORNAMENTALS ASSOCIATED WITH LEAKING NATURAL GAS

STUDIES OF THE CONDITION OF TREES ALONG CURBS AND IN MEDIANS OF STREETS IN WILMINGTON, N. C., SHOWED THAT NATURAL GAS WAS LEAKING INTO THE SOIL. THIS GAS DISPLACES THE SOIL AIR TO SOME EXTENT AND PROVIDES AN ENVIRONMENT SUITABLE FOR NATURAL GAS UTILIZING BACTERIA. UNDER ANAEROBIC SOIL CONDITIONS MICROORGANISMS TRANSFORM SULFATES TO HYDROGEN SULFIDE. HYDROGEN SULFIDE INTERFERES WITH ROOT RESPIRATION AND NUTRIENT UPTAKE WITH THE ULTIMATE RESULT BEING THE DEATH OF THOSE WOODY PLANTS GROWING IN THE SOIL. NITROUS OXIDE IS ALSO PRODUCED UNDER ANAEROBIC CONDITIONS AND MAY BE AN ADDITIONAL STRESS FACTOR. /DOT/
