ROADSIDE EROSION CONTROL

Soaking bermudagrass sprigs four hours in water was equally as effective in promoting root and shoot development as the best treatments from five growth regulators. MS-2 on Coherex produced better aggregation of a Vernon-Lucien complex clayey soil for 45 days than Curasol or Petroset. Curasol applied to a Teller fine sandy loam provided the best aggregation for 45 days. The best erosion control on a Vernon-Lucien soil complex was obtained from an excelsior blanket, bluestem hay, and excelsior fiber in this descending order. J M Fiber Tileguard mat was found to be unsuitable as a protective mulch for 10 plant species. Wherever possible all seeds should be drilled preferably, for establishment of erosion resitant ground covers. Grasses that seem to be best adapted on the man- made soils east of US-81 with 25 to 45% slope, that are loamy, shallow, and acidic are K. R. bluestem and weeping lovegrass on south facing cut slopes followed by bermudagrass. Weeping love seems to be best on north facing cut slopes followed by K. R. bluestem. On clayey, shallow to very shallow, soils in this area, basic in reaction, bermudagrass seems to be best on east and west facing cut slopes. West of US-81 on soils with a 25 to 45% slope, loamy deep to shallow, and basic, switchgrass and sideoats grama seem to be best on north facing cut slopes. On south facing cut slopes weeping lovegrass seems to be best. On loamy, very shallow, basic soils in this area sideoats grama seems to be best on either east or west facing cut slopes. Southland smooth promegrass, fertilized with 100-80-60/acre, will provide the quickest protection from soil erosion when compared to Kentucky 31 tall fescue, or crested wheatgrass seeded on highly erodible. Bates- Collinsville complex soil that had been loosened by dishing prior to seeding. Two years after seeding the best ground cover would be provided by either Southland smooth brome or crested wheatgrass fertilized with 100- 80-60/acre.
