The goal of the study was to find the best ways to grow grass from seeds for controlling erosion on roadsides. The researchers looked at different methods like how to plant the seeds, using weed killers, types of mulch, and how to prepare the soil. They found that using weed killers helped a lot in controlling erosion. The best results came from using an excelsior blanket as mulch. Chiseling the soil before planting the seeds was the most effective tilling method.
