dc.description.abstract | Vertisols have the capacity to swell and shrink, inducing cracks and distinctive soil structure throughout the soil profile. The formation of these specific features is caused by a heavy texture, a dominance of swelling clay and marked changes in moisture content. in this study, benchmark Vertisols of Panjari and Kheri sub-humid (moist) region, Teligi and Akola soils semi-arid dry and Nimone arid agro-ecological region. All the Vertisols are characterized by dark colour in surface, angular to sub-angular blocky structure, clayey texture, and slight to strongly effervescent from upper to lower horizon of the soil profiles. These soils have high bulk density and water retention capacity. In addition, they have deep wide-opened desiccation cracks at the surface which extend deep into the profiles and the depth of cracks increase with increase in aridity. The slickensides are found beginning at a shallower depth in arid climate, whereas they are observed at lower depths in wetter climates. Soils of all climates are dominated by Cap' ion in their exchange complex throughout the depth. However, in the sub-humid climate me ions tends to dominate in the lower horizon. The semi-arid dry (Akola) soils have high Na` ions in soil solution. This facilitated the translocation of Na-clay in the soil profile and is responsible for the increase in pH. The soils are slightly alkaline to alkaline and poor in organic matter. The CEC varied from 40.8 to 50.18 cmol (rf) kg'' in Panjari soils which is highest followed by Teligi soils. The calcium carbonate (CaCO3) shows gradual increase with depth in all the soil profiles, though it is preferentially accumulated in the sub-surface horizons of lower rainfall region soils. In climo-sequence the soils of the sub-humid region are generally Typic Haplusterts, soils of semi-arid region are Typic/Sodic/Calcic Haplusterts and soils of arid region are Sodic/ Calcic/ Aridic Haplusterts. The available potassium content (1 NNH4OAc extractable) of these soils is very high and available nitrogen is low. The potassium content in sub-humid moist (Uteri) soil is high in surface horizon followed by semi-arid dry (Akola) soil. The ratio of exchangeable to non-exchangeable K varied from about 1:4 to 1:7. The variation is mainly due to mixing of different parent materials during the process of their formation. | en_US |
