FERTILIZATION AND EROSION ON A NEW HIGHWAY
THE EFFECTS OF NITROGEN AND PHOSPHORUS FERTILIZATION OF A TURF MIXTURE CONSISTING OF TALL FESCUE KENTUCKY BLUEGRASS, REDTOP AND ALSIKE CLOVER ON EROSION OF THE LEVEL, CUT AND FILL SLOPES OF A NEW HIGHWAY WERE STUDIED. THE EFFECT OF FERTILIZATION ON COVER VARIED WITH LOCATION AND INITIAL FERTILITY LEVELS. EROSION DEVELOPED FIRST ON THE EAST SIDE OF THE CUT SLOPE ON PLOTS RECEIVING ONLY NITROGEN OR PHOSPHORUS OR NOTHING. NO EROSION DEVELOPED IN 4 YRS IN PLOTS FERTILIZED AFTER CONSTRUCTION WITH BOTH NITROGEN OR PHOSPHORUS, ALTHOUGH BARE AREA IS DEVELOPING. COVER IN THE FORM OF STRONG VIGOROUS GRASSES WAS NECESSARY FOR THE PREVENTION OF EROSION. PERCENT GRASS COVER ALONE COULD NOT BE CORRELATED WITH ITS EROSION-PREVENTING CAPACITY, AS EVIDENCED BY THE APPEARANCE OF COMPLETELY BARE AREA OR OF SMALL GULLIES. /AUTHOR/
