| Abstract/Contents: | "Persistence of vegetation planted along roadsides in cold climates is often limited because of multiple stresses including the application of salt, prolonged ice encasement, poor management, poor soil quality, and weed competition. This study was conducted in conjunction with a multi-site roadside trial assessing the performance of seeded turfgrass species and mixtures. Understanding the seed bank could help us identify and characterize weed pressure between and among individual sites. Sites were located at seven locations in Minnesota. After tillage of each site, prior to seeding, soil was collected and bulked by block. Three 200-g subsamples were taken per block resulting in 63 samples (7 locations x 3 blocks x 3 subsamples). Soils were stored for approximately 5 months at -1 C for the first 2 months and -7 C for the remaining 3 months at which time they were placed in pots in a greenhouse. The seedling emergent method was used to quantify the total number, weed type, and life cycle as plants emerged and were identified. A total of 837 plants were identified from 52 species resulting in an average of 12.5 plants per sample. Of the 46 species, 10 were grasses, 32 were broadleafs, four were trees, and one was a cattail. Digitaria sanguinalis (large crabgrass) and Digitaria ischaemum (smooth crabgrass) represented approximately 63% of the total quantity. A Pearson correlation test indicated species richness across location was correlated moderately with percent sand and potassium levels (0.49 and -0.43 respectively). The total number of identified plants was significantly greater at two of the seven sites. This study has enhanced the characterization of each individual roadside research testing location. The high percentage of warm-season annual grasses suggests that roadside turfgrass installers should avoid late spring establishment and a pre-emergent herbicide application in the spring may be important for dormant seedings." |
