Regional Optimization of Roadside Turfgrass Seed Mixtures Phase 2: Regional Field Trials and Economic Analysis

Current Minnesota Department of Transportation (MnDOT) specifications for roadside turfgrasses suggest statewide planting of mixtures grouped into five broad categories such as low maintenance turf and high maintenance turf. Based on our communication with county engineers throughout the state, some mixtures appear to be better adapted to particular areas. Therefore, the objectives of this study are to (1) determine if MnDOT should be specifying turfgrass mixtures based on climatic regions of the state, and if so, to determine what the appropriate turfgrass mixtures are for each region and (2) quantify the costs associated with the installation of roadside turfgrasses (both seed and sod) so that public land managers can make informed decisions.
