Abstract

The relation between soil moil moisture and matric potential referred to as SOIL MOISTURE characteristics curve, is one of the most fundamental soil physical properties. Field and laboratory methods of measuring this relationship are time-consuming and costly. Therefore, developing methods that estimate SOIL MOISTURE (q#) at SPECIFIC SUCTIONs from easily available and simple properties of soil will be advantageous to researchers and general users. The one-parameter model of Gregson et al. (G.H.M) is based on log-log form of SOIL MOISTURE characteristics curve as ln z# =a+b ln q#. In this equation (a) and (b) are constants and have a negative correlation as a=p+qb. Using this equation and substituting it in the first equation results in the Gregson et al one-parameter model:lnz# =p+q(q+ln q#). In this equation (p) and (q) are regression coefficients and have specific values for each textural class, and only the parameter (b) is unknown. This parameter was estimated by Shirazi-Boersma soil textural diagrams values (geometric mean diameter and geometric standard deviation). To develop this model, 290 soil sample data from different laboratories were used and also 30 undisturbed soil samples were used to test the model. These samples were grouped into 8 TEXTURAL CLASSES and finally. (p) And (q) and (b) were calculated for each one of the 8 TEXTURAL CLASSES. Results showed that estimating SOIL MOISTURE at specific matric potentials with the model has R__^2 greater than 0.9 for each textural class.
