Grasses and their Establishment as Turf Along Newly Graded Highways.

摘要

A summary is presented of the findings of an investigation of roadside turf establishment conducted at the University of Illinois from 1959until 1967. Major portions of the investigation include a literature review,study of species adapted to use on highway rights-of-way,study of lime and fertilizer requirements,study of competitive effects between grasses and legumes and study of time of seeding and seeding mixtures. Species now used for seeding mixtures in Illinois generally were found to be well adapted to conditions within the State. A recommendation for application of agricultural limestone based on chemical tests of the soil has been adopted. It was found that temporary seedings are not needed at any time during the growing season except in late fall after it is too late to seed perennial species. (Author)
