SOIL TEMPERATURE DISTRIBUTION IN BULDANA

The objective of this work is to study the monthly and daily variation of soil temperatures at various depths at Buldana. This knowledge will facilitate the suitable placement of Earth-Air Heat Exchanger. A 3-m deep temperature probe was installed in the campus of Rajarshi Shahu Polytechnic, Buldana . Readings were taken over a period of one year. The probe has six temperature sensors, mounted at 60 cm intervals. The probe was buried in a vertical position. The first sensor is at ground level, the second at 0.6 m depth, third at1.2 m, the fourth at1.8cm, the fifth at 2.4 m and the sixth at a depth of 3 m. Temperatures from all the sensors were noted everyday for a year. Readings were noted in the morning at 8 am, noon at 1 pm and evening at 5 pm. In this paper, the results are presented. Temperatures were noted at intervals of 1 hour on some days in every month.
