Abstract

The present study was conducted to study the spatial variability of soil acidity (pH), electrical conductivity (EC), texture and calcium carbonate (CaCO3). The total of 23 soil samples were collected from different plots at 0–0.3 m in depth and were analyzed in the laboratory. The statistical analysis showed high spatial variability across the experimental field based on EC, CaCO3, clay, sand and silt indicated by values of the coefficient of variation (CV) of 46.537, 38.156, 32.289, 49.037 and 34.742%, respectively. However, very low variability was observed for soil pH; with CV value of 2.759%. Correlation matrix indicated that soil pH was significantly correlated with CaCO3 (r=0.74) and electrical conductivity (r=-0.448). Clay was positively and significantly correlated with silt (r= 0.635) and negatively and significantly correlated with sand (r=0.907). Silt was negatively and significantly correlated with sand (r=-0.907).
