ROAD SALT /SODIUM CHLORIDE/ INJURY TO KENTUCKY BLUEGRASS

THE FACTORS WHICH HAVE A BEARING ON SALT INJURY TO PLANTS ARE CENTERED AROUND THE MAIN DELETERIOUS EFFECTS OF SODIUM CHLORIDE ON PLANTS' DIRECT TOXICITY TO THE PROTOPLASM, AND HIGHER WATER TENSION IN THE PLANT. THESE FACTORS ARE PLACED UNDER NINE HEADINGS AS FOLLOWS' /1/ AMOUNT OF ROCK SALT APPLIED, /2/ AMOUNT OF ROCK SALT REACHING THE VEGETATION, /3/ WATER AVAILABILITY, /4/ EXPECTED TEMPERATURES, /5/ EXPECTED WIND VELOCITY, /6/ SOIL FACTORS, /7/ PLANT DORMANCY , /8/ SALT TOLERANCE OF PLANTS, AND /9/ CUMULATIVE EFFECTS. THIS STUDY HAS SHOWN THAT SUFFICIENT ROCK SALT WAS APPLIED TO PARK ROADS TO CAUSE THE DEATH OF THE KENTUCKY BLUEGRASS TURF ALONG THE ROADSIDES. WITH INCREASING USE OF SODIUM CHLORIDE, THE DECLINE AND DEATH OF THE VEGETATION CAN BE EXPECTED TO CONTINUE. THE QUALITATIVE CHEMICAL METHOD FOR DETERMINING SODIUM CHLORIDE INJURY AS PROPOSED BY THOMAS APPEARS SATISFACTORY FOR DETERMINING ROCK SALT INJURY. MORE ACCURATE RESULTS ARE OBTAINED WHEN TESTS ARE MADE SOON AFTER INJURY OCCURS. REFERENCES' A QUALITATIVE MICROCHEMICAL METHOD FOR DETERMINING SODIUM CHLORIDE INJURY TO PLANTS, L. K. THOMAS JR., U. S. NATIONAL PARK SERVICE SCI. REPT., 4'23-32, 1965.
