• Abstract:
  Tests were installed in 1971 to modify roadside soil materials limiting plant growth and to develop chemical treatments for controlling unwanted vegetation. Plastic clays which show a poor tendency toward granulation can be modified by treatment with cationic polymers to favor vegetation establishment. Other treatments such as gypsum and certain soil amendments were not satisfactory. Plating with topsoil was very satisfactory, and better stands of grass were secured when topsoil was not mixed with the clay material. Treatment of extremely acid material with massive rates of lime is effective for at least three years. The acidity increases gradually over this time. Annual and some perennial plants can be selectively controlled in multiflora rose hedges, but most perennial weeds persist.
