Researchers discover potential solutions to New England roadside erosion

Erosion is a significant problem on highway embankments in New England. Typically,"A mixture of red fescue, perennial ryegrass, and kentucky bluegrass is planted to stabilize the soil, but only the red fescue survives". Rhode Island researchers designed a study to identify alternative grass species that could help anchor slopes and prevent costly erosion. Combined results of the greenhouse and roadside trials showed little bluestem, purple lovegrass, and tall fescue to be the best choices.
