Mapping soil properties in Bangladesh's cropping regions helps understand soil health. Researchers collected 92 soil samples from different crop areas and measured pH, nutrients, and more. They used geostatistical analysis to show how soil properties vary across the region. Results suggest that soil properties differ even within small areas. The kriging interpolation method was effective in mapping soil properties with low error. These maps can guide farmers and decision-makers in managing nutrients efficiently and reducing input costs. Geostatistics and GIS techniques are powerful tools for regional nutrient management.
