Boro rice areas were delineated from Sentinel 2B images of March, 2021 by using standard visual interpretation technique. Soil fertility status of Boro rice feilds was evaluated by using soil sample analysis data collected from Soil Health Card dashboard and soil sampled collected from different rice fields in GIS environment. Soil sample location map was prepared from latitude and longitude information and soil analysis data was linked to it. The soil fertility maps were generated through Inverse Distance Weighted (IDW) interpolation technique using Spatial Analyst tools of Arc Toolbox. The study revealed that Boro rice is cultivated over 7647.9ha which is 15% of the total geographical area of the Selsella block. The soils of Boro rice fields are non-saline, slightly acidic, high to medium in organic carbon and sufficient in iron, manganese, zinc and copper content. The availability of phosphorus and potassium varies from medium to low and nitrogen availability is high to medium.
