NEUTRON METER USE IN SOIL-MOISTURE MEASUREMENTS: A REPORT OF A SURVEY CONDUCTED BY THE U.S. WORK GROUP ON NUCLEAR TECHNIQUES IN UNSATURATED AND SATURATED ZONES

THE ANSWERS TO A QUESTIONNAIRE SENT TO 350 PERSONS FROM WHICH 200 RESPONDED HAVE BEEN CORRELATED TO PROVIDE UP-TO- DATE INFORMATION ON THE USE OF NEUTRON METERS IN SOIL- MOISTURE MEASUREMENT. COMMERCIAL INSTRUMENTS ARE USED CHIEFLY, AND THE NUMBER IN USE INCREASES STEADILY. FIELD CALIBRATION REMAINS A DIFFICULT PROBLEM. THE METHOD IS IN USE FOR EVERY HYDROLOGICAL PROBLEM THAT REQUIRES A SOIL- MOISTURE MEASUREMENT. A REAL NEED EXISTS FOR RESEARCH AND DEVELOPMENT TO INCREASE THE RELIABILITY OF THE METERS IN FIELD USE. TWO BIBLIOGRAPHIC LISTS ARE APPENDED TO ILLUSTRATE THE SCOPE OF PRESENT WORK. /AUTHOR/
