Estimation of randomiand spatial variability (both horizontal and vertical) of sodic soils in semiarid climatic region of Haryana showed that the pH, EC, OC, available P and CaCO3 contents were normally distributed. Soil pH showed least variation while CaCO3 varied the most. Tree growth varied due to content of CaCO3 and soil pH.
