CONTROL OF ROADBANK EROSION IN THE SOUTHERN PIEDMONT

PRELIMINARY RUNOFF AND SOIL LOSS MEASUREMENTS MADE DURING THE 2-YEAR PERIOD, 1958-59, AT BARE, ROADBANK SITES IN THE PIEDMONT OF NORTHWEST GEORGIA INDICATED THAT SOIL LOSSES WERE EXCESSIVE. HIGHWAY ROADBANKS WERE EFFECTIVELY STABLIZED BY SEEDINGS OF ADAPTED SPECIES. THE MOST PROMISING SPECIES INCLUDE 4 GRASSES (TALL FESCUE, COMMON BERMUDAGRASS, COASTAL BERMUDAGRASS, AND LOVEGRASS), TWO LEGUMES (CROWN VETCH AND LESPEDEZEA SERICEA), AND, FOR STEEP, ROCKY SLOPES, TWO VINES (HONEYSUCKLE AND KUDZU). IN THIS AREA TALL FESCUE IS FALL SEEDED, WHEREAS THE BERMUDAGRASSES AND LOVEGRASS ARE ESTABLISHED IN THE SPRING. CROWN VETCH STARTS SLOWLY FROM SEED AND A PROTECTIVE MULCH IS REQUIRED DURING SEEDLING ESTABLISHMENT. THE MOST PROMISING WAY OF PROVIDING THIS PROTECTION IS TO SEED ABRUZZI RYE WITH THE CROWN VETCH. THE FALL-SEEDED RYE BECOMES ESTABLISHED RAPIDLY AND PROVIDES A STRAW MULCH BROWN IN PLACE AS PROTECTION FOR THE SEEDLINGS OF CROWN VETCH. CROWN VETCH DEVELOPED MORE RAPIDLY WHEN PLANTED IN SEPTEMBER AND OCTOBER, BUT PLANTINGS WERE SUCCESSFULLY MADE IN ALL MONTHS, SEPTEMBER TO MARCH, INCLUSIVE. THIS COMBINATION WAS PARTICULARLY PROMISING IN THESE STUDIES. MULCHES WERE ESSENTIAL FOR HOLDING SEED AND FERTILIZER IN PLACE ON STEEP SLOPES. MULCH WAS ESSENTIAL TO INSULATE AND PROTECT SLOWLY DEVELOPING SPECIES ON ALL SLOPE CONDITIONS. MULCH WAS NOT SO ESSENTIAL FOR RAPIDLY DEVELOPING GRASSES ON MODERATE SLOPES. CROP STRAW MULCHES OR MULCH GROWN IN PLACE WITH ABRUZZI RYE WERE SUPERIOR TO OTHER MULCHES TESTED. /AUTHOR/
