Abstract: Soil fertility plays a key role in increasing crop production in the soil which comprises not only in supply of nutrients but also their efficient management. The research study was conducted for evaluate the Physico-chemical properties and soil fertility status of 171 soil samples taken from Masalpur, hindaun city and Mandrayal block in Karauli district of Rajasthan under CFLD’S of NMOOP and NFSM Project during 2017-2018. Soil samples were taken from demonstrator’s fields of 10 villages (0-15 cm depth) and analyzed for their physico-chemical properties to prepare the map on the basis of nutrient status in the soil. The average pH, EC and organic carbon percent of soil samples were observed 7.65, 0.45 dSm^-1 and 0.50% respectively in Masalpur block followed by Hindaun city block (7.54, 0.47 dSm^-1 and 0.53% respectively) and Mandrayal block (7.66, 0.49 dSm^-1 and 0.52% respectively). The pH was showed in neutral range while EC and organic carbon percent was low range for cultivated land of three blocks. Available nitrogen kgha^-1, phosphorus kgha^-1, potassiumkgha^-1 were found in Masalpur block (228.79 kgha^-1, 17.98 kgha^-1 and 127.67 kgha^-1 respectively) followed by Hindaun city block (232.86 kgha^-1, 16.09 kgha^-1 and 176.49 kgha^-1) and Mandrayal block (212.62 kgha^-1, 15.60 kgha^-1 and 152.79 kgha^-1 respectively). The Available Nitrogen, Potashkgha^-1was showed in low range fertility status while Available Phosphoruskgha^-1 was showed medium range fertility status from three blocks of research study. Hence, use of chemical fertilizers, Vermicompost, Micronutrients in the soil for improvement the fertility status of soil required for a specified crop.
