| Sustainable soil management with appropriate understanding of soil characteristics is vital in maintaining and improving soil fertility. The objectives of thepresent study is to characterize the spatial variability across a soil for selected using GIS technique. A total of 120 geo-referenced representative soil samples (from 0 to 0.60 m depth) were collected from Sahl Al-Hussainiyah, Sharkia Governorate, Egypt. Analyses included pH,ECe, CaCO3, soil organic matter (OM), available N, P and K,cations exchange capacity (CEC) and bulk density (BD). Spatial distribution pattern varies from moderate to strong. The best fit semivariogram model of ECe, K and BD was stable model, whereas K-Bessel model was the best fit model of pH, OM and CEC.With the exponential model, the best fit was with CaCO3, N and P.According to the spatial distribution map, five zones were identified, where the study area was classified to <7.17, 7.17 to 7.41; 7.41 to 7.66; 7.66 to 7.89, and > 7.8 for pH, < 6.70, 6.71 to 8.17; 8.18 to 9.73; 9.74 to 11.4, and > 11.5 dSm-1 for EC, < 2.3, 2.31 to 2.92; 2.93 to 3.76; 3.77 to 4.52, and > 4.53% for CaCO3, < 0.43, 0.44 to 0.52; 0.53 to 0.61; 0.62 to 69, and > 0.70% for OM, < 30.3, 30.3 to 37.9, 37.9 to 45.6, 45.6 to 52.6, and > 62.6 mg kg-1 for N, < 1.61, 1.62 to 2.43; 2.44 to 3.31; 3.32 to 4.30, and > 3.41 mg kg-1 for P. < 103, 104 to 113; 114 to 124; 125 to 132, and > 132 mg kg-1 for K, < 43.2, 43.2 to 46.8; 46.8 to 50.8; 50.8 to 55.8, and > 55.8 cmolc kg-1 for CEC and < 1.27, 1.28 to 1.32; 1.33 to 1.39; 1.40 to 1.51, and > 1.52 Mg m-3 for BD. Thus, this methodology can be used succsseffly in Spatial Variability of some soil properties. | ||||
