Abstract:

Seed variety performance data for establishing temporary vegetative cover was collected at four Illinois locations ; at four planting seasons. Current Illinois Department of Transportation (IDOT) standard specifications call for a ; mixture of perennial rye and spring oats for temporary vegetative cover, with no variation for time of year or site ; conditions. That mixture has demonstrated some success; however, for every location and time of year, this ; study identified at least one seed variety that demonstrated performance superior to the specified mix. Temporary ; seeding specifications currently employed by nearby states were reviewed and compared with Illinois’ ; specifications. In addition to seed variety, the effectiveness of seed bed preparation using a power rake and the ; effectiveness of straw-mat and loose wheat-straw mulching methods were investigated. ; Based on the observed results, the research team has proposed modifying temporary seeding recommendations ; to reflect seeding date and site location. Adoption of these research-based temporary seeding specifications will ; likely result in improved temporary vegetative cover establishment, reduced erosion, and improved water quality
