| Abstract |
De Vries 1963 and Hanks 1992 methods were used to estimation volumetric heat capacity as function of soil properties . Data indicate that , the mean values of volumetric heat capacity of the stuied soils estimated by using the De Vries method are higher by a factor 1.29 times than Hnks method . The correlation coefficient between values of DeVries and Hanks is postive and highly significant r= 0.94984** ) The simple regression between values of volumetric heat capacity MJ/m3C of De Vries 1963 Y1 and values of Hanks 1992 Y2 was as following
Y1=0.291099 +0.332857 Y2
R=0.96484**
Where
Y1 = Volumetric heat capacity values MJm3C according to De Vries method 1963
Y2 = volumetric heat capacity values MJm3C-1 by Hanks method 1992
The multible regression between values of volumetric heat capacity MJ/C1) ,fine sand C2 , SILT % C3 , clay C4 , Ca CO3 C5 , and EC dSm-1) C6 are highly signifacint r= 0.889** and r= 0.944** respectively , and the equation representing
Y1 = 0.557842+ 1.0874E-002C1 +1.1517E-00C2 +7.489E004 C3+1.2766E002C4+7.1599E003C5 –4.323E-002C6
R= 0.889**
Y2 = 0.275434 + 1.0516E-002C1+1.1830E002C2-2.2835E003C3+1.4864E002C4-1.2186E-003C5-1.3665E001C6
R=0.944**
Where
Y1= volumetric heat capacity values (MJm3C –1) according to DeVries method 1963
Y2 =volumetric heat capacity values MJm30C-1 by Hanks method 1992
It is clear that volumetric heat capacity values is likely not only a function of particular soil system , but also depend upon the method of estimated used
