A periodic tendency of increased soil temperature at
10 cm depth revealed the distinctive attribute of this
particular soil thermal environment, which indicates
the degree of soil warming during summer (Table 1).
Soil temperatures fluctuated at 5 and 10 cm depths.
The temperature range at 5 cm depth was 16.50C and
10.50C at 10 cm depth. Tang et al. (2011) argued
that variations in soil temperature occur at different
soil depths and its importance at any given period and
the pattern of fluctuations depend greatly on space
and time.
