Abstract: Soil fertility maps namely pH, EC, OC (Physical parameters); P, K (Macro nutrients) and Zn, Fe, Cu, Mn (Micro nutrients) were generated using Geographic Information System from grid wise soil health data. The study revealed that soils of Ri Bhoi district is non saline with high organic carbon content. It is observed that soils of 68.87% area of the district are slightly acidic and 26.22% soils are moderately acidic in nature. The availability of phosphorus is medium in 73.93% soils followed by high and low phosphorus that covers 14.16% and 11.91% area respectively. The highest area (i.e.66.49%) of the district is having medium available potassium followed by high and low potassium that covers 19.97% and 13.60% area respectively. The soils of the study district are mostly rich in micronutrients and more than 80% areas are sufficient in micronutrient contents. Only 15.48% area is deficient in zinc whereas iron, copper and manganese is deficient in <1%, 1.02% and 6.06 % areas respectively.
