Mapping spatial variability of soil properties is the key toefficient soil resource management for sustainable crop yield. Therefore,the present study was conducted to assess the spatial variability of soilproperties such as acidity (pH), salinity (electrical conductivity (EC)),organic carbon, available K, available P, exchangeable Ca2+,exchangeable Mg2+, available S and hot water soluble B in surface (0–20 cm)and subsurface (20–40 cm) soil layers of oil palm plantations in southGoa district of Goa located in west coastal area of India. A total of 128soil samples were collected from 64 oil palm plantations of Goa located atan approximate interval of 1–2 km and analyzed. Soil was acidic to neutralin reaction. Other soil properties varied widely in both the soil layers.Correlations between soil pH and exchangeable Ca2+, between soil EC andavailable K, between available P and available S and between exchangeableCa2+ and exchangeable Mg2+ in both the soil layers were found tobe positive and significant (P < 0.01). Geostatistical analysisrevealed a varied spatial distribution pattern for the measured soilproperties. Best-fit models for measured soil properties were exponential,Gaussian, stable, K-Bessel and spherical with moderate to strong spatialdependency. The results revealed that site-specific fertilizer managementoptions needed to be adopted in the oil palm plantations of the study areaowing to variability in soil properties
