A study was undertaken to characterize fine textured Inceptisols morphologically, physically and chemically. Seven profiles in fine textured and four in coarse textured Inceptisols under different cropping systems (rice-wheat, maize-wheat, sugarcane, fallow-berseem and rice-sorghum) were exposed for the morphological, physical and chemical characterization. The soils showed remarkable closeness irrespective of profile locations and horizons. All the studied soils exhibited A-Bw-C horizons in coarse textured Inceptisols and A-B horizons in fine textured Inceptisols. The lower horizon has lower chroma and value followed a definite pattern. In fine textured Inceptisols clay content varied from 26-68 % and depth distribution of bulk density did not show any definite pattern with clay content and the cropping systems. No subsurface compaction was observed in fine textured Inceptisols. The soils were non-saline and alkaline in reaction. The depth distribution of CEC did not show any definite trend and varied with clay content. Calcium plus magnesium content was the dominant cations followed by potassium and sodium among all the exchangeable cations. These soils have severe physical constraints due to the presence of large amounts of clays in the finer fractions leading to lower crop productivity in these soils.
