Rapid urbanization and industrialization are leading cause of food security issue in modern days, so there is dire need to efficiently utilize the scarce resources. Increased food per unit area is an indispensable factor to tackle food security. Therefore, a research survey was carried out to evaluate the salinity and fertility status of district Sahiwal to execute balanced and environment friendly fertilizer recommendation to the farmers to gain maximum output from different crops of this area. A total of 14490 soil samples were collected from two tehsils of Sahiwal (Tehsil Chichawatni and Tehsil Sahiwal) and analyzed for physico-chemical properties in Soil and Water Testing Laboratory, Sahiwal. About 81% soils had EC values (≤ 4.0 dSm-1) which were non-saline in nature and 74% of total soil samples exhibited normal pH value < 8.5. Organic matter status of 90% soil samples was deficient ˂ 1%. The available phosphorus in 45% samples were poor ( i.e., ≤7.0 mg kg-1), Potassium contents of most (70%) of the soils were satisfactory having 80-180 mg K kg-1 soil. The results of this study indicated that the most of soils of district Sahiwal are good for agricultural crops production but with low fertility status
