dc.description.abstractIn the present study twenty representative pedons were selected based on topography from various physiographic units identified in Agri Bio Diversity Park of Acharya N. G. Ranga Agricultural University, Rajendranagar, Hyderabad and on the basis geomorphic units, soils were selected from Upland, Midland and Lowland. All the pedons were studied for their morphological characteristics and horizon wise samples were processed for physical, physico-chemical and chemical characteristics. Based on morphology and analytic data profiles were characterized and classified. The soils were very shallow to deep (5 to 60 cm), dark red to very dark greyish brown (2.5 YR 3/6 – 10YR 3/2), excessively well drained. The results showed that variation in soil properties strongly influenced on land form and topography. The analysis of soils indicated that the upland soils are shallow, midland and lowland soils are medium to deep, but along the slope the depth of soil increased along with other physical properties like clay, water holding capacity, infiltration rate and bulk density. The pH is neutral to moderately alkaline (6.5 to 8.04), low to high in organic carbon (0.18 to 0.96 %), low to medium in CEC (11.5 – 26.5 c mol (p+) kg-1). The base saturation indicated that non-fertile to very fertile and soil texture was sandy loam to sandy clay loam with variation in relation to physiography. The upland soils were exhibiting higher bulk density, particle density and lower water holding capacity, midland and lowland soils were recorded higher infiltration rate and clay percentage. In all soils pH, OC and CEC were consistently increased with depth. The organic carbon content and CEC were higher in lowland soils, which might be due to the clay translocation and organic carbon content accumulation. The soils are low to medium in available N (92.3 to 351.5 kg ha-1), low to medium in available P (6.22 to 28.2 kg ha-1), low to high in available K (93.1 to 293.4 kg ha-1), deficient to sufficient in available S (7.1 to 21.2 mg kg-1). The available micro nutrients are sufficient in all the profiles. Based on morphological, physical, physio-chemical, chemical and meteorological data, soils were classified according to the revisions of USDA soil taxonomy (2006), that out of 20 profiles ten profiles (P4, 5, 7, 9, 10, 11, 12, 13, 19 and 20) belongs to order of Inceptisoils, six profiles belongs to order of Alfisols and other remaining are Entisols. All soils were classified up to the family level. The upland soils classified as coarse loamy, Iso-megathermic, Typic, Ustorthents (P16, 15 and 18). Further, the profiles P4, 5, 10, 11, 12 and 20 were classified as coarse loamy, Isomegathermic and Haplustepts and P2 were fine loamy, Iso-mega thermic, Typic Rhodustalfs. The soils of Agri Bio Diversity Park were classified on the basis of Landscape position that is uplands, midlands and lowlands. Uplands recorded primarly Entisols (P8, 15, 16 and 18) and midland soils with one Inceptisol indicating a transition from Entisols to later Inceptisols. Further Uplands also recorded Inceptisol, where the pedogenic process and the soil development initiated through horizination. The Alfisols were observed in the midlands (P2, 3, and 6) and lowlands (P1, 11 and 17), illustrating the development of a matured profiles, with a good depth in all horizons with sequence. The study evidently indicate that the topographically and relief plays an important role in soil development. The detailed soil survey was conducted in Agro Bio Diversity Park. Topographical map by using instrument total station was developed with scale 1:2500. Further, on the basis of the topographical and planimetric data, two sites were identified for the construction of check dams with an ultimate objective of conservation and management at 0.5 contour interval was prepared. The soil resource inventory for identifying the soil related constraints has `been prepared based on field survey and laboratory investigation. Further the major constraints like erosion, runoff and drainage resulting in soil material loss must be controlled with a combination of various practices in a system approach especially with trees, crops and an abiotic component may be integrated for the restoration and conservation of soil and land resources including native flora and fauna insitu. Hence appropriate soil and water conservation practices needed to be undertaken simultaneously to conserve and preserve the native flora and fauna which are found in Agro Bio Diversity Park of Acharya N.G. Ranga Agricultural University, Hyderabad. It is concluded that characterization and classification of Agri Bio Diversity Park soils basic information at initial stage is useful to overcome the soil management constraints for further development and maintenance of park in better way.en_US
