The present investigation entitled “Delineation of Soil Fertility Maps of Deolali Pravara Village, Rahuri Tehsil” was carried out during 2024-2025 with the objective of determining the nutrient profile of local agricultural soils. GPS-based grid sampling was employed to collect 130 representative soil samples at 0-15 cm depth, followed by laboratory analysis of physico-chemical properties. The soils were moderately alkaline (mean pH 8.27), low in available nitrogen (184-313 kg ha⁻¹), low to medium in available phosphorus (8.25-28.73 mg kg⁻¹), and medium to high in available potassium (281-612 kg ha⁻¹). Micronutrients (Zn, Fe, Mn, Cu) exhibited spatial variability, with deficiency of zinc being most widespread. Bulk density values averaged 1.37 Mg m⁻³, reflecting good porosity in clay and silty clay soils. Fertility maps prepared using GIS highlighted zones of nutrient deficiency and surplus, enabling
site-specific nutrient management recommendations. The study emphasizes the role of digital mapping in precision agriculture and sustainable resource management.
