FERTILIZED NATIVE PLANTS PROMISE QUICK AND CHEAP ROADBANK PROTECTION

RESEARCH AT THE COOSA WATERSHED RESEARCH PROJECT IN GEORGIA IS SHOWING THAT FERTILIZER AND LIME WILL ENCOURAGE NATURALLY SEEDED NATIVE PLANTS. IN THESE EXPERIMENTS, A COMPLETE FERTILIZER WAS APPLIED TO THE IMPOVERISHED NATIVE SPECIES, ALONG WITH LIME, AND WITH AND WITHOUT SURFACE MULCHES. THE RESPONSES OF THE NATIVE SPECIES TO SOIL FERTILITY TREATMENTS WERE SO GREAT THAT A SEPARATE STUDY ON FERTILIZER RATES WAS INITIATED. ALL OF THE DIFFERENT RATES OF THE FOUR-TWELVE-TWELVE PLUS NITROGEN RESULTED IN VIGOROUS GROWTH AND DEVELOPMENT OF THE NATIVE SPECIES AS A PROTECTIVE COVER ON THE LOWER TWO-THIRDS OF THE BANK THE FIRST GROWING SEASON AFTER FERTILIZER TREATMENT. BROOMSEDGE AND POVERTY GRASSES WERE THE PREDOMINANT SPECIES THAT DEVELOPED DURING THE FIRST TWO YEARS. A COVER OF HONEYSUCKLE, DEWBERRIES, AND OTHER NATIVE SPECIES ALSO DEVELOPED AS A RESULT OF THE FERTILIZER APPLICATION. IT APPEARS THAT ROADBANKS MAY BE CONSERVED QUICKLY AND CHEAPLY IN THE SOUTHERN PIEDMONT BY APPLYING 500 POUNDS OF 4-12-12 FERTILIZER AN ACRE FROM FEBRUARY TO MAY, FOLLOWED BY 50 POUNDS OF NITROGEN AN ACRE IN MAY OR JUNE. ON VERY STEEP ROADBANKS IT IS ESSENTIAL TO MULCH THE SURFACE TO HOLD THE FERTILIZER AND LIME UNTIL VEGETATION CAN BE ESTABLISHED.
