SEEDING METHODS FOR UTAH HIGHWAYS

THE RESULTS AND RECOMMENDATIONS OF THE HIGHWAY SEEDING STUDY ARE SUMMARIZED. TOPSOILING TO A 6-INCH DEPTH WAS FOUND TO BE ESPECIALLY IMPORTANT TO OBTAINING SATISFACTORY GRASS STANDS ON HIGHWAY SLOPES. FERTILIZERS APPLIED AT THE TIME OF PLANTING HAVE SHOWN NO BENEFICIAL EFFECTS. NITROGEN APPLIED DURING THE FALL FOLLOWING THE FIRST GROWING SEASON PRODUCED A SUBSTANTIAL INCREASE IN THE VIGOR OF SEEDLINGS INCREASING THEIR SURVIVAL AND ESTABLISHMENT. METHODS, RATES, TIMES, AND SPECIES OF SEEDLING ARE DISCUSSED AND RECOMMENDATIONS FOR VARIOUS CONDITIONS ARE MADE. SEVERAL MULCHES WERE TRIED UNDER DIFFERENT EXPOSURE SITUATIONS. THE MULCHES CONSERVE MOISTURE BY REDUCING EVAPORATION FROM THE SOIL AND HELP MINIMIZE EROSION. MOST MULCHES WHEN PROPERLY APPLIED, GIVE ADDED BENEFITS IN GETTING GRASS ESTABLISHED ON CUTS AND FILLS. WEED CONTROL IS CONSIDERED IMPORTANT BECAUSE ANNUAL WEEDS AND GRASSES COMPETE WITH THE PLANTED SEEDLINGS AND MAY PREVENT ESTABLISHMENT OF A GOOD STAND. A COMBINATION OF PRE-EMERGENT AND POST EMERGENT HERBICIDES IS GENERALLY RECOMMENDED. ONLY LIMITED MOWING SHOULD BE DONE BY MAINTENANCE FORCES AND CARE SHOULD BE TAKEN NOT TO MOW TOO CLOSE TO THE CROWN OF THE PLANT. ALLOWING THE PLANT TO PRODUCE SEED IMPROVES THE VIGOR OF THE EXISTING PLANT AND AIDS IN SEEDING FOR NEW GROWTH. /FHWA/
