TURF ESTABLISHMENT AND MAINTENANCE ALONG HIGHWAY CUTS

THE PRESENT PAPER IS AN EXTENSION OF PREVIOUS WORK, REFERENCED BELOW, IN WHICH IT WAS SHOWN THAT SUCCESSFUL SOD ESTABLISHMENT ALONG HIGHWAYS DEPENDS ON (1) ADEQUATE LIME AND FERTILIZER, (2) CHOICE OF SEED MIXTURES WITH ADAPTED GRASSES AND LEGUMES; (3) ELIMINATION OF AGGRESSIVE OR LOW SEEDING RATES OF COMPANION GRASSES SUCH AS RYE GRASSES AND CEREALS; (4) SUITABLE SEEDING DATES; AND (5) LIGHT APPLICATIONS OF MULCH. TWO SETS OF FURTHER EXPERIMENTS WERE CONDUCTED. IN THE FIRST, AN INFERTILE CUT OF RED TO GREYISH SUBSOIL OF GNEISS AND SCHIST ON A 1:15 SLOPE IN SOUTHERN PIEDMONT VIRGINIA WAS USED. THE SOIL HAS A PH OF 5.0 AND WAS LOW IN PHOSPHORUS, CALCIUM, AND MAGNESIUM AND MEDIUM HIGH IN POTASH. THE RED SUBSOIL MATERIAL FROM THIS EXPERIMENT WAS ALSO USED FOR A GREENHOUSE POT EXPERIMENT TO STUDY GROWTH AS RELATED TO LIMING. THE SECOND EXPERIMENT DEALT WITH SUBSOIL OF THE SAME ACIDITY BUT HIGHER FERTILITY. RESULTS OF MANIPULATING THE VARIABLES IN THESE EXPERIMENTS ARE REPORTED.
