| Özet |
| Salinization is one of the most important limiting problems of plant growth in Turkey as it is in all over the World. Salinity differs from other soil characteristics in terms of spatial distribution structure and has mainly patchy distribution. Therefore, better management of salinity can only be achieved by mapping the salinity of soils. The purpose of this study was to determine the most acceptable method to estimate the values of attributes related to soil salinity in Çerikli Irrigation Planning Area located in central Turkey. The coverage area of study area is 14.924, 00 ha. Disturbed soil samples were collected from 0-30 cm, 30-60 cm and 60-90 cm depths of 110 sampling locations. Soil samples were analyzed for soil pH, electrical conductivity (EC), sodium adsorption ratio and water extractable Ca, Mg, Na and K concentrations. The estimation performance of deterministic (Radial Basic Functions (RBF) and Inverse Distance Weighting (IDW)) and Stochastic (Ordinary Kriging, Simple Kriging and Universal Kriging) interpolation methods have been compared for the predication of soil salinity in the project area.(Salinity/EC) in 0-30 cm depth ranged from 0.65 and 67.1 dS/m with a mean value of 8.90 dS/m, in 30-60 cm depth EC ranged from 0.86 dS/m and 79.9 dS/m, and in 60-90 cm depth EC ranged from 1.07 dS/m and 98.80 dS/m. The root mean square error (RMSE) of the methods was used to compare and determine the best method. The mean absolute error (MAE) value was used in case of having the same RMSE value. The RBF-ST provided the accurate results for the EC of 0-30 cm and 30-60 cm depths and the RBF-IM was the most appropriate … |
