STUDY OF ENVIRONMENTAL REQUIREMENTS OF PLANTS TO SECURE SATISFACTORY VEGETATIVE COVER OF DISTURBED AREAS EXPOSED DURING GRADING OPERATIONS

DURING THE THREE YEAR PERIOD ENDING IN 1964 THIS STUDY EXPLORED THE EFFECT OF SEEDING DEPTHS AND DATES, SOIL COMPACTION, SPECIES, MULCHES, FERTILIZERS AND COMPANION CROPS ON THE ESTABLISHMENT OF GRASSES AND LEGUMES ON FIVE DIFFERENT ROADSIDE SOIL TYPES, AND IN A GREENHOUSE IN SOUTH DAKOTA. IT WAS DETERMINED THAT 70 TO 80 POUNDS OF NITROGEN AND 160 -185 POUNDS OF PHOSPHOROUS PER ACRE SHOULD BE USED WITH ALL SEEDINGS MADE ON SUBSOIL ROADSIDE AREAS. THE EFFECTIVENESS OF STRAW MULCH WAS LESSENED AS A RESULT OF COMPETITION FROM VOLUNTEER CEREALS. TWO VARIETIES OF WHEATGRASS AND ALFALFA SHOULD FORM A PART OF ALL SEED MIXTURES. SOWING DEPTHS SHOULD BE WITHIN THE RANGE FROM 1/2 INCH TO 1 INCH, IN A COMPACTION SITUATION APPROXIMATING A NATURAL ENVIRONMENT, AND SHOULD BE DONE DURING THE NOVEMBER-MAY PERIOD, PREFERABLY IN APRIL. /BPR/
