Abstract

Information to regarding spatial variability and distribution of soil characteristic is critical to increase use efficiency of nutrients and desire crop productivity for farming communities. Application of nutrients on the basis of soil characteristics maps connected with fertilizers recommendation may aid to curtail fertilizers input without surrendering the crop yield. For assessing the variability in soils fertility status using geo-statistical approaches, total 90 GPS based surface (0-15 cm) soil samples were collected from three districts (Morena, Bhind and Sheopur) of Chambal division after crop harvest, during rabi season 2019-20. The results revealed that pH, EC, OC and CaCO3 of soils varied from 5.80 to 8.65, 0.12 to 0.89 dSm-1, 1.50 to 10.20 g kg-1 and 1.0 to 65 g kg-1 soil, respectively. Whereas, available N, P, K and S in soils ranged from 71.25 to 348 kg ha-1, 7.14 to 92.12 kg ha-1, 60 to 620 kg ha-1 and 0 to 72 mg kg-1, respectively. The deficiency of N, S, and Zn were fo

Conclusion

Soils of Chambal division were found neutral to slightly acidic to alkaline in reaction, safe in electrical conductivity, deficient to medium in organic carbon, non-calcareous in nature, extent of N deficiency in soils samples were to the extent of 83.41 % and extent of K excess in soils samples were to the extent of 89.76 % and extent of Cu, Mn and B excess in soils samples were to the extent of 98.59, 94.37 and 76.06 per cent, respectively. Application of fertilizers on the basis of soil characteristics maps associated with fertilizers recommendation may aid to curtail fertilizers input without surrendering the crop yield.
