MULCHING PRACTICES AND MATERIALS

THIS PAPER IS BASED ON INFORMATION RECEIVED FROM THE HIGHWAY DEPARTMENTS OF 48 STATES AND FROM SEVERAL OTHER AGENCIES INVOLVED IN EROSION CONTROL WORK. STANDARD SPECIFICATIONS OF ONE ADDITIONAL STATE HIGHWAY DEPARTMENT PROVIDED SOME INFORMATION ON STANDARD PRACTICES. AS A RESULT OF THIS RESPONSE THE FIRST OBJECTIVE COMPILING STANDARD PRACTICES AND MATERIALS HAS BEEN ACCOMPLISHED. THERE SEEM TO HAVE BEEN NO REVOLUTIONARY CHANGES IN PRACTICES AND MATERIALS, BUT THERE HAS BEEN A DECIDED INCREASE IN THE NUMBER OF STATES STARTING TO USE MULCH DURING THE PAST TWO YEARS. IN THE SAME PERIOD A NUMBER OF NEW PRODUCTS HAVE BEEN DEVELOPED FOR USE IN MULCH DURING THE PAST TWO YEARS. IN THE SAME PERIOD A NUMBER OF NEW PRODUCTS HAVE BEEN DEVELOPED FOR USE IN MULCHING OPERATIONS. SOME HAVE BEEN USED IN A LIMITED EXPERIMENTAL WAY AND OTHERS HAVE BEEN EXPERIMENTED WITH ON A COMPARATIVELY LARGE SCALE DURING 1960. A SURVEY IS MADE OF EXPERIMENTAL MULCHING PRACTICES AND MATERIALS, INCLUDING THE FOLLOWING, SAWDUST, WOOD PULP, ELASTOMERIC POLYMER EMULSIONS, STARCH, TOBACCO STEMS, PINE STRAW, MUSHROOM COMPOST, RESIN ADHESIVE, DOSIUM SILICATE, PLASTIC, FILM, AND JUTE AND PAPER BLANKETS CONTAINING SEED, FERTILIZER, PH CONTROL, VERMICULITE, GRUB CONTROL AGENTS, AND ORGANIC MULCH.
