Title: EROSION CONTROL ON EXTREMELY SANDY SOILS IN NEW JERSEY
Accession Number: 00205062
Record Type: Component
Abstract: THE METHODS USED IN STABILIZING THE SURFACE OF SAND FILLS IN THIS AREA DEPEND ON EXISTING CONDITIONS AND AVAILABLE MATERIALS. TOPSOIL IS USED WHEN IT CAN BE STRIPPED FROM THE GRADED WIDTH OF THE NEW ROADWAY OR WHEN IT CAN BE BROUGHT IN ECONOMICALLY FROM OUTSIDE SOURCES. PEAT AND MUCK DEPOSITS WHICH MUST BE EVACATED AS UNDESIRABLE SUBGRADE MATERIAL ARE ALSO USED. TESTS HAVE SHOWN THAT, IN SOILS CONTAINING SOME CLAY, SILT, AND COLLOIDS, A LESS COSTLY REFERTILIZATION PROGRAM OBVIATES THE NEED FOR EXPENSIVE ORGANIC SUPPLEMENTS. WIND EROSION IS OF SMALL CONSEQUENCE ALONG OUR HIGHWAYS; HOWEVER, IT IS A PROBLEM ALONG LOCAL STREETS IN THE IMMEDIATE VICINITY OF THE COASTAL BEACHES. IN SUCH AREAS WOODEN SNOW FENCES ARE OFTEN ERECTED DURING THE WINTER MONTHS TO IMPORTANT EXISTING VEGETATION CONSISTS OF BEACH GRASS, BEACH GOLDENROD, SILVERROD, AND HUDSONIA. THE EARLY ESTABLISHMENT OF TURF ON SLOPES IS IMPORTANT. SLOPES SHOULD BE AS FLAT AS PRACTICABLE AND RUNOFF SHOULD NOT BE ALLOWED TO CONCENTRATE WHERE IT CAN FLOW DOWN THE SLOPE. WHERE THE TURF IS DESIRABLE, TOPSOIL SHOULD BE USED IF AVAILABLE, SINCE ITS USE IS THE SUREST WAY TO ESTABLISH TURF WIT THE LEAST AMOUNT OF FUTURE MAINTENANCE. THE USE OF SHRUBS AND TREES IS A VALUABLE AID IN STABLILIZING A SLOPE, BUT ONLY SPECIES OF PROVED ABILITY TO WITHSTAND CONDITIONS OF POOR SOIL, LOW FERTILITY, DROUGHT, AND EXPOSURE SHOULD BE USED. THREE GENERAL TYPES OF SLOPE TREATMENTS INVOLVING EXTREMELY SANDY CONDITIONS ARE IN USE.
