IMPROVED ESTABLISHMENT AND MAINTENANCE OF ROADSIDE VEGETATION IN MICHIGAN

THIS INVESTIGATION OF RAPID, UNIFORM ESTABLISHMENT OF A VEGETATIVE COVER FOR MICHIGAN ROADSIDES INVOLVED 22 EXPERIMENTS CONDUCTED FROM 1963 TO 1970 ON LOAMY CLAY CUT SLOPE, LOAM CLAY FILL SLOPE, SANDY CUT SLOPE, SANDY MEDIAN, AND SANDY LOAM MEDIAN SITES. SEED MIXTURE STUDIES INDICATED THAT A MINIMUM OF 20%, ON A SEED NUMBER BASIS, EACH OF KENTUCKY BLUEGRASS, RED FESCUE, AND PERENNIAL RYEGRASS SHOULD BE INCLUDED AS THE BASIC COMPONENTS OF THE SEED MIXTURE. THE OPTIMUM SEEDING RATE WAS IN THE 80 TO 100 POUND PER ACRE RANGE. ADEQUATE ESTABLISHMENT WAS ACHIEVED WITH SEEDINGS MADE DURING THE PERIOD FROM MAY 1 TO OCTOBER 10. THE SOIL INCORPORATION OF 80 POUNDS PER ACRE OF NITROGEN, PHOSPHORIC ACID AND POTASH WAS THE BEST SEEDBED FERTILIZATION PRACTICE. THE MULCHES THAT PROVIDED ADEQUATE SOIL STABILIZATION AND THE PROPER MICROENVIRONMENT FOR SEED GERMINATION AND GRASS ESTABLISHMENT WERE: STRAW MULCH (2 TONS PER ACRE) PLUS ASPHALT (150 GALLONS PER ACRE); SOIL RETENTION MAT OR EXCELSIOR; AND SHREDDED WOOD AND BARK (9 TO 10 TONS PER ACRE). /AUTHOR/
