Minnesota Regional Roadside Seed Bank Analysis

Abstract

Persistence of vegetation planted along roadsides in cold climates is often limited because of salt, prolonged ice encasement, poor management, poor soil quality, and weed competition among other stresses in the northern United States. Seed banks at different sites could be a major driver influencing the type of coverage with turfgrasses commonly growing immediately adjacent to roadsides. This study was conducted in conjunction with a multi-site roadside trial assessing the performance of seeded turfgrass species and mixtures.
