This research was carried out in Şeyh Hasan village of Baskil district of Elazığ province covering about 400 ha. It was aimed to determine spatial distribution for total nitrogen (N), available phosphorus (Kav) and available potassium (Pav) elements of soils under different agricultural uses. For this aim, total 174 soil samples were collected from surface depth (0-15 cm) in the study area. In order to determine spatial distribution of samples, five different interpolation models were applied and the most suitable model was detected. Thus, spatial distribution maps of total N, Pav and Kav were generated using the most model for each. According to obtained distribution maps, N and Kav concentrations were sufficient by taking into consideration of FAO classes, whereas only small part of the study area was insufficient as to P av concentration.
