Abstract

Fifty one registers (one every week) of soil temperatures in
51 weeks through twelve months from January to December were
recorded for every depth. They were recorded for three soil depths
(0.05, 0.15, and 0.30m) in sandy soil that covered with alfalfa
plants in Ismailia Agriculture Research Station of Ismailia
governorate. The total soil temperature registers recorded were (51
observations x 3 depths) 153 readings. One hundred and fifty three
soil samples in the same 51 weeks were collected from the same
locations of the three depths. The volumetric heat capacity, thermal
conductivity and thermal diffusivity were calculated. The obtained
results were summarized as follows:
Soil volumetric heat capacity increased with increasing
moisture content at the nearest soil surface depth (0.05m) or the
deepest one (0.30m). They ranged from 1.345479 to 1.803934,
1.286049 to 1.678707 and from 1.281804 to 1.757947 MJm-3c-1 for
the three depths 0.05, 0.15 and 0.30m respectively.
Soil thermal conductivity increased with increasing soil
moisture content. The values ranged from 1.2603 to 2.2489,
1.23222 to 2.15026 and 1.03913 to 2.18332Jm-1s-1c-1, at moisture
content ranged from 0.024 to 0.133, 0.010 to 0.103 and 0.009 to
0.122m3m-3 for the abovementioned depths, respectively. However,
soil temperature showed a small effect on increasing the thermal
conductivity.
Soil thermal diffusivity was affected by soil temperature and
soil volumetric moisture content. They ranged from 9.22592E-07 to
13.3223E-07, from 9.10083E-07 to 14.0327E-07 and from
8.1068E-07 to 15.1938E-07 m2s-1 at three depths of 0.05, 0.15 and
0.30m respectively.
