Abstract |
This investigation was carried out to study the effect of moisture content in two levels at field capacity and wilting point on volumetric heat capacity. The volumetric heat capacity were estimated by Dr Vries method (1963). The results indicated that increase moisture content with increase the volumetric heat capacity. So the value of volumetric heat capacity at field capacity more than its value at wilting capacity. The ratio of mean values of volumetric heat capacity at field capacity in to mean value of volumetric heat capacity at wilting point was 4.60 times for the data set. And also highly significant and positive correlation between moisture content at field capacity and wilting point and volumetric heat capacity values(MJm30c-1)r= 0.79888 and 188 respectively. The multiple regression between values of volumetric heat capacity at field capacity or at wilting point with CaCO3% , O.M. % and EE dSm-1 are highly significant (0.90988 and 188) respectively , according to the following equation :
γ1=3.900776- 9.294 E0.001C1-1.1438E+002 C2 + 7.0186E +001C3 + 3.5451 C4 γ2+1.594906 +2.1483E-003 C1+ 7.2740E-002C2+ 1.4181E-001C3+4.1447C4
Where :
Y 1= volumetric heat capacity at field capacity%
Y2= volumetric heat capacity at wilting point%
