SELECTION, ESTABLISHMENT, AND MAINTENANCE OF VEGETATION FOR EROSION CONTROL OF ROADSIDE AREAS IN GEORGIA
One hundred and ninety-two sites distributed throughout Georgia were planted to mixtures of grasses and legumes. The wide distribution allowed sampling of the varied soils, climate, and topography of roadsides. Topsoil was added to half the sites at planting. Treatments of no supplemental fertilization, biennial fertilization, and annual fertilization have been maintained at each site. Observations were made twice yearly during a six year period. Results confirm the location of zone boundaries dividing the state into Mountain, Piedmont, Coastal Plains, and Flatwoods zones as shown in the Phase I report. Initial fertilization has been reduced and topsoil eliminated from grassing contract requirements. Legumes, especially sericea lespedeza, are better adapted in the Piedmont and Mountain zones than the grasses planted in this project. Centipedegrass is the best alternative to the widespread bahiagrass in the Coastal Plains and Flatwood zones. Legumes are difficult to maintain in South Georgia. /FHWA/
