ABSTRACT
Ten representative pedons from rice-growing soils of Northern Telangana region were characterized and classified. The results showed that the soils were of sandy loam to clay in texture with low permeability. In general, the soils were neutral to slightly alkaline in reaction, high to low in organic carbon, mixed in mineralogy and moderately deep to very deep. Bulk density increased with depth and values ranged from 1.33 to 1.95 Mg m-3. Water retentions at 0.33 bars and 15 bars of soils ranged from 8.8 to 46.7 % and 3.9 to 25.8 %, respectively. In most of the pedons soil pH increased with depth. Cation exchange capacity of soil followed no definite distribution pattern with depth. The status of N, P and K was low to medium, low to high and low to medium respectively. The available N, P and K decreased with depth. Based on soil characteristics, the soils of Karimnagar (P8) were classified as Alfisols, soils of Satyanarayanapuram (P1), Armoor (P2), Nandipeta (P4), Adilabad (P5), Basara (P6) and Ichoda (P7) were classified as Vertisols, soils of Rudrur (P3), Jagithyala (P9) and Peddapalli (P10) were classified as Inceptisols.
