Özet
The objective of the study was to investigate the heavy metal contents of common soil groups and spatial distribution in agricultural land of Siverek district in Sanliurfa, Turkey. A total of 76 soil samples in Siverek district of Sanliurfa province was obtained from two depth ranges (0-20 and 20-40 cm) and 38 separate spots in order to represent common soil groups. Salt, texture (clay, sand and silt), pH, line (CaC03), organic matter (OM) and heavy metal (Cd, Co, Cr, Ni, Cu, Fe, Mn and Zn) content were determined in samples. Descriptive statistics and correlation analysis were performed in transformed data from the soils of field of study. Maps of spatial distribution of heavy metal concentrations generated using kriging interpolation of data from two different depths (0-20 and 20-40 cm). Average pH, salt, lean and organic matter contents of soil were between 7.54-7.57, 0.06-0.06%, 3.64-3.84% and 1.89-1.99%, respectively. Ranking of average heavy metal values in research soils (0-20 and 20-40 cm) were Mn > Fe > Cu > Ni > Zn > Co > Cd > Cr. Semivariogram ranges for heavy metal content of research soils which defines maximum distance of spatial correlation was between 16 and 64 km. A positive correlation between Cd with Ni, Cu, Mn and Zn contents of soils was determined according to the results. Strong and weak heavy metal profiles of common soil groups in Siverek district of Sanliurfa exhibited as a result using heavy metal data sets and kriging interpolation methods. © 2020 Parlar Scientific Publications.
