Özet:
This research was carried out in the context of evaluating the temperatures at different soil depths observed as monthly between 1970-2019 in Ulukışla district of Nigde province in Turkey. In the study, maximum, minimum and average soil temperatures at soil depths of 10, 50 and 100 cm were investigated. Sperman’s Rho, Mann-Kendall and Sen's slope method tests on soil temperature data were applied. According to trend analysis results; The general average of maximum soil temperatures of 10 cm depth was 22.0°C, minimum soil temperature values were 6.9 °C and average soil temperatures were calculated as 14,0 °C. The general average of the maximum soil temperature values in 50 cm soil depth was calculated as 16.1 °C, minimum soil temperature values were observed as 11.5 °C. The general mean of average soil temperatures were determined as 13,8 °C. The general average of the maximum soil temperature in 100 cm soil depth was determined as 15.4 °C, minimum soil temperature values were calculated as 12.6 °C, average soil temperature values were observed as 14.0 °C. According to the changes in soil temperatures in different soil depths; It was determined that there was an increasing trend in maximum, average and minimum soil temperature values in spring, winter, autumn and summer.
