Abstract:
Present study was carried out in Gwalior Chambal division of Madhya Pradesh state, India with the aim of fertility status evaluating of soils using nutrient index approach, mainly for primary nutrients (N, P & K) as well as sulphur. Soils of the studied areas were sandy loam to sandy clay loam in texture with normal calcium carbonate content. Electrical conductivity was normal (<1.0 dS m^-1) and pH of soils (7.32 to 8.32) was normal to moderately alkaline. Surface soils contained more organic carbon content as compared to sub surface soils and were low to medium in all the land use system except forest. Maximum surface soil samples of available nitrogen was low (80%), whereas more than half (> 50%) soil samples were in medium category in available phosphorus, potassium and sulphur. Nutrient index value for available N was found to be low (<1.67 range) and for available phosphorus, potassium and sulphur were medium (1.67 to 2.33).
