POSSIBLE EFFECTS ON SOIL AND WATER RESOURCES OBSERVED IN NEVŞEHİR PROVINCE IN LONG ANNUAL TEMPERATURE AND RAINFALL CHANGING
This study is performed in Nevşehir province at central Anatolian parts of Turkey. The aim of the current study was to investigate the yearly changes of rainfall and temperature climatic parameters in the long data period from 1975 up to 2014 years. The total of 40 years precipitation and temperature monthly data were first separated and classified seasonally and then were assessed by Mann-Kendall and Spearman Rho tests. The long term average of monthly rainfall data was recorded about 421 mm and the average temperature amount was calculated 20.9 °C for summer months. The maximum and minimum temperature values in summer months were recorded 33.5 °C and 7.7 °C respectively. The study was performed on long term rainfall and temperature data sets in order to investigate the transformations effects on soil and water resources, and that was obvious the rainfall data did not follow an increasing slope within different years, but a serious additive trend was observed in the average, maximum and minimum long term temperature amounts. Moreover along with the increasing temperature rate at the region, the growing surface water vaporing was recorded. The gradual reduction of rainfall amounts causes some difficulties in solution and absorption of fertilizer nutrient elements by plants and in addition leads to unsufficient amounts of soil moisture in dry farming lands.
