Abstract
There are 14 stations under the supervision of Extension Sector. Ministry of Agriculture and Land Reclamation. Those stations are scattered all-round the country and record the entire climate data daily or whatever it is needed. Agricultural climate data were collected along the recorded period (FeO.1 51 to March 31. 2002). Data of the
. previous years was not used since the climate was significantly changed) from station located at Sedi Salem, Kafr El-Sheikh Governorate to represent the North Delta region.
It could be conclude' that the high temperature decline along the soil layer (0 - 20 em). _Tt:is led all the estimated statistics (max high, low high. min high, min low, range high. range low, STDV high and STDV low) to be declined along the soil layer (0 - 20 ern). Consequently. soil temperature change is affected in the upper layer (Scm) and then decline sequentially in the sequenliallayers .
. The relationship between the lowest, highest clnd mean temperatures in the upper soil layer (5 cm) and high air temperature is derived and represented by the equations 1· 3 below:
Soil low temperature (at 5.cm depth) =
. O:7783x(high. air temperature) ·3.0406 (1)
. 'R2::: 0.621
Soil high temperature (at 5-cm depth) ":; 0.9084x(high. air temperature) + 2.344 (2)
R2 '" 0.6779
Soil mean temperature (at s-cm depth) ::: O.8433x(high. air temperature) ·0.3483 (3)
R2::: 0.67'26
These equations provide whom it may be concerned (researchers, extension workers and farmers) by a very simple method to get a quick prediction of soil temperature just by knowing air temperature which is so easy and available to any person. In order to cultivate cotton in the proper time as MALR recommend.
