SOIL-WATER POTENTIAL: DIRECT MEASUREMENT BY A NEW TECHNIQUE

CURRENT METHODS OF MEASURING THE POTENTIAL OF WATER IN SOIL ARE INADEQUATE. IT IS PROPOSED TO DEPRESS THE REFERENCE FREE ENERGY OF WATER BY A PREDETERMINED AMOUNT FROM THE STANDARD LEVEL OF PURE FREE WATER AT ATMOSPHERIC PRESSURE BY USE OF A SOLUTE. THE SPECIFIC FREE-ENERGY DIFFERENCE OF SOIL WATER FROM THE DEPRESSES REFERENCE CAN BE MEASURED AS A PRESSURE. /AUTHOR/
