Abstract

Digital maps of soil parameters are traditionally generated by dragging and drop** the desired tool of Geographical Information System (GIS) under the project of the Soil Health Card (SHC), India, and require knowledge in GIS, time, cost, and human resources to complete at the country level. Thus, there is need for a model, to generate soil parameter-wise maps quickly and efficiently. A model was proposed based on the Model Builder in ArcMap of ArcGIS for the automatic creation of files: interpolation, reclassification, color, raster to polygon, union, projection, and legend information for the generation of soil fertility maps. The model was validated using data (n = 161) from the SHC, Chitrasari (village), Bihar (state), India. Model results show that a map of one soil parameter can be produced in less time, at a lower cost, and with minimum human intervention as compared to traditional manner. The coefficient of variation (CV) of soil parameters varied from 6 to 112.9%. Micronutrients are positively correlated. The soil pH had a significantly negative correlation with Fe, Cu, and Mn. Soil B, Fe, K, Mn, N, OC, P, S, and Zn deficiencies were found in 16.59, 15.73, 7.64, 17.21, 1.0, 1.46, 0.61, 26.03, and 74.41% of the study area, respectively. The proposed model was implemented to create maps for 500 SHC model villages. Therefore, this model could be an effective tool for planners and decision-makers to identify issues at the village level and take timely action to save earth, soil health, environment, and site-specific fertilizer management.
