Abstract: The present investigation was carried out to study the morphological and physicochemical characteristics of different soil profiles of Chhattisgarh and classify them. Nine pedons belonging to different agro- climatic zones of Chhattisgarh were studied for morphological and physico-chemical characteristics during summer season of 2006. Soil profiles were studied for depth, colour, texture, structure and consistency. Horizon wise soil samples were collected and analysed for mechanical composition, pH, EC, organic C and CEC. Out of nine soils studied, Nardaha soil of Chhattisgarh plain, Madpal and Kachnar soils of Bastar plateau were shallow. Phunderdihari soil of Northern hills zone, Banrasi soil of Chhattisgarh plain and Chokar soil of Bastar plateau were moderately deep while the Rajpuri soil of Northern hills zone, Darba and Jora soils of Chhattisgarh plain were deep with well-developed horizons. Shallow soils were coarser while deep soils were finer in texture. Soil colour varied from light red in Nardaha soil of Chhattisgarh plain through reddish brown in soils of Bastar plateau, yellowish brown in soils of Northern hills zone to light olive brown in Jora soil of Chhattisgarh plain. Moderate, medium and sub angular blocky structure (2, m, sbk) was common in all the pedons and almost all the horizons of the profiles in three agro-climatic zones. Wet consistence of soils varied from slightly-sticky, non-plastc (ss, po) in Madpal and Kachnar soils of Bastar plateau through slightly sticky, slightly plastic (ss, sp), sticky and plastic (s, p) in Northern hills zone to very sticky and very plastic (vs, vp) in Jora soil of Chhattisgarh plain. All the soils belonging to Northern hills zone and Bastar plateau and Nardaha soil of Chhattisgarh plain were acidic (pH < 6.0) in soil reaction while the soils of Banrasi, Darba and Jora belonging to Chhattisgarh plain were in the normal range. Salt content in these soils were in the safe limit for crops. All the soil of different agro-climatic zones were low in respect of organic carbon content except Chokar soil of Bastar plateau and Jora soil of Chhattisgarh plain which were in the lower margin of medium category. Acidic soils were having low CEC as compared to normal soils. Nardaha soil of Chhattisgarh plain and Madpal and Kachnar soils of Bastar plateau were classified as Lithic Ustorthents, Phunderdihari soil of Northern hills zone, Banrasi soil of Chhattisgarh plain and Chokar soil of Bastar plateau as Typic Hapluestepts, Rajpuri soil of Northern hills zone and Darba soil of Chhattisgarh plain as Typic Haplustalfs, and Jora soil of Chhattisgarh plain as Typic Hapluesterts at subgroup level.
