The establishment of plants on the roadside is difficult at many sites due to the highly disturbed soils that are present after highway construction. Four Interim reports were prepared during the three year period that this project covered. These reports were on the use of 'slow release' fertilizers as a nitrogen source for landscape plants; the factors that influence nitrogen fixation by woody plant species; the effects of various mulches on the growth of landscape plants; and various methods for establishing plant cover on the roadside by seeding. This report presents summaries of the four Interim Reports that were submitted.
