Precision Farming (PF) is a technology already available for sustainable agriculture production, which enable farm management based on the small-scale spatial variability of soil and crop parameters in the field. This study was undertaken to determine the status of Nitrogen (N), Phosphorus (P) and Potassium (K) variability in Durian Orchard Farm at Bendang Man Agrotourism Project, Sik, Kedah (Phase 1). The Orchard Farm (Phase 1) has an area of 3.75 ha with latitude 5°51'29"N and longitude 100°49'33"E to 100°49'42"E. The objectives of the study are to: (i) determine the level of soil nutrient (NPK) variability in a durian orchard using Geostatistic and (ii) produce a soil nutrient (NPK) map of the durian orchard for efficient fertilizer management. The NPK nutrient was analyzed and then mapped by Geostaitic Plus Software (GS++) to quantify the spatial dependence and structure to predict values at unsampled location and finally tra nsferred into ArcView software. Results indicated that N, P, K ranged from 0.1 to 1.0 % (N), to 45 ppm (P) and 0.8 to 1.4 cmol (+)/kg (K), respectively, results indicated that the study area in general has in not sufficient N while K are suffient
