| Abstract |
The currient investigation is carried out to study thermal conductivity values of different soil textural classes . The soil samples were collected from Abu Rawash ,Cairo Alxandria road and Nubaria region . Their textual classes of these soils wereloamy sand , sandy and sandy clay loam . The thermal conductivity estimated according to devries method . the result indicated that mean values of thermal conductivity MJs0C of air dry loamy sand , sandy and sandy clay loam were 2.9614 E06,3.3059E-06 and 1.44223E-06 respectively
The multiple regression between thermal conductivity values at air dry soil (MJms-10C) and coarse sand (C1) ,Fine sand (C2) ,silt % (C3) ,clay % (C4) ,CaCO3 (C5) ,organic matter C6 and EC C7 are highly significant r =983**and the equation representing
Y1=33.763753-3.1751E-001(C1)-3.2063E-001(C2)-2.8319E-001(C3)-1.8774E-001(C4)-1.5615E-001(C5)+5.5951E-001(C6)-2.0794E-001(C7) r=0.983**
The multiple regression between thermal conductivity values at air dry soil MJmsC and pore size distribution quickly drainable pores QDP % , slow drainable pores SDP % c2 water holding pores WHP % and fine capilary pores % FCP % C4 are significant r= 312** and the equation representing
Y2 =7.845568-9.8956E-002C1-7.425EC2+9.9142E-002C3-3.9978E-001C4
