AN INSTRUMENT FOR SOIL MOISTURE DETERMINATION

A PORTABLE MOISTURE METER COMPRISING A SOIL UNIT AND A METER UNIT, CAPABLE OF MEASURING SOIL MOISTURE FROM SATURATION POINT TO LEVELS MUCH BELOW THE WILTING POINT, HAS BEEN DESIGNED AND CONSTRUCTED. THE SOIL UNIT USES TWO MOISTURE-SENSITIVE ELEMENTS, ONE MADE OF A PLASTER OF PARIS- FIBERGLASS COMBINATION FOR THE MOISTURE RANGE FROM SATURATION POINT TO THE WILTING POINT AND THE OTHER MADE OF PLASTER OF PARIS ALONE FOR MOISTURE CONTENTS BELOW THE WILTING POINT. THE AVAILABLE WATER PERCENTAGE (FOR PLANTS) IN THE SOIL IS OBTAINED FROM THE METER READING BY REFERENCE TO A STANDARD CALIBRATION CURVE, WHILE THE ACTUAL MOISTURE CONTENT IS DETERMINED BY REFERENCE TO A SEPARATE CALIBRATION CURVE ESPECIALLY OBTAINED FOR THE PARTICULAR SOIL. /AUTHOR/
