Abstract/Description: | Vertisols have the capacity to shrink and swell, inducing cracks and distinctive soil structure throughout the soil profile. In India they occur in various agro-ecological regions such as humid tropical (HT), sub-humid moist (SHM), subhumid dry (SHD), semi-arid moist (SAM), semi-arid dry (sAD) and arid dry (AD) climatic environments and thus indicate al affay of soils in a climosequence. In this study benchmark Vertisols, series Panjari is from sub-humid (dry), Kheri is from sub-humid (moist) region, Teligi and Akola series are from semi-arid (dry) and Nimone is from arid agro-ecological region. All the Vertisols in general are characlenzed by dark colour, angular to sub-angular blocky structure, clay in texture and calcareous. These soils have high bulk density and high water retention capacity. These soils have deep, wide-opened desiccation cracks at the surface which extend deep into the profiles and the depth of cracks increases with aridity. Soils of all climates are dominated by Ca2+ ion on their exchange complex throughout the depth. However, in the sub-humid climate, Mg2+ ions tends to dominate in the lower horizons, whereas the semi-arid dry (Akola) soils have high Na+ ions in their exchange complex. The soils are slightly alkaline to strongly alkaline in nature and poor in organic matter. The CEC varied from 59.3 to 68.2cmol (p.) kg' in soil of Panjari series followed by Teligi series profile. The calcium carbonate (CaCO,) shows gradual increase with depih in all the soil profiles, though it is preferentially accumulated in the sub-surface horizons of lower rainfall region soils.In climosequence, 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 I Calcic / Aridic Haplusterts. The present study dernonstrateq how the soil properties of Vertisols in a different climate may help in inferring the change in climate in a geologic period. |
