RESULTS OF ROADSIDE TESTS WITH SOIL CONDITIONERS IN 1952

A QUESTIONNAIRE WAS SENT TO ALL STATE HIGHWAY DEPARTMENTS TO SECURE INFORMATION ON THE RESULTS OBTAINED FROM APPLICATIONS OF SOIL CONDITIONERS IN TESTS ALONG HIGHWAYS DURING 1952. THE PRESENT REPORT IS BASED ON 21 QUESTIONNAIRES RETURNED FROM THE NINTEEN STATES WHERE TESTS WERE CONDUCTED, FROM THE DEPARTMENT OF HIGHWAYS OF THE DISTRICT OF COLUMBIA, AND FROM THE NATIONAL CAPITAL PARKS. TWELVE OF THE QUESTIONNAIRES EACH REPORTED ON TEN OR MORE TESTS. ONE STATE REPORTED ON FORTY-TWO TESTS. THE MOST COMMON MATERIALS TESTED WERE DIFFERENT FORMULATIONS OF KRILIUM (MONSANTO CHEMICAL COMPANY). OF THESE, THE BIG MAJORITY OF THE TESTS WERE WITH THE FORMULATIONS NO. 9 AND NO. 991. THREE OF THE QUESTIONNAIRES REPORTED ON TESTS WITH AEROTIL (AMERICAN CYANAMID COMPANY). TESTS WERE CONDUCTED ON SEVERAL DIFFERENT TYPES OF SOIL AND ON SLOPES OF DIFFERENT RATIOS. THE CHEMICALS WERE APPLIED ON THE SURFACE ONLY IN SOME TESTS, WHICH IN OTHERS THEY WERE WORKED INTO THE SOIL BY DIFFERENT METHODS. OF THE TWENTY-ONE QUESTIONNAIRES REPORTING TESTS, ELEVEN REPORTED SOME INDICATIONS OF BENEFITS FROM THE USE OF SOIL CONDITIONERS FOR CHECKING SOIL EROSION. SOME OF THESE REPORTS ARE QUALIFIED BY COMMENTS THAT INDICATE THESE BENEFICIAL RESULTS WERE LIMITED AND INCONCLUSIVE AND WERE NOT AS GOOD AS RESULTS FROM USE OF MULCHES.
