The basic principle of precise fertilization is to adjust the fertilizer input according to the specific circumstances or properties of soils in each location to minimize the loss and maximize the profit. To know the secondary and micro-nutrient in surface soil of Baleswar district, 360 geo-referenced surface soil samples were collected at 2 × 2 km grid interval in different land uses like rice, maize, pulses etc. Data indicated that deficiency of boron (B) were highest followed by zinc (Zn) and sulphur (S). Soils were sufficient in DTPA-Fe whereas deficiency showed by Mn and Cu were recorded in same patches. Three nutrient deficiencies (B+Zn+S) were observed in 15% of soils in the district.
