Soil physical and physico-chemical properties of soils of Jangon district in Telangana state

Seven typical pedons from of Jangon district were studied for physical, physico-chemical and chemical properties of the area. The soils were moderately deep to very deep, reddish brown to dark reddish brown in colour, gravelley sand to clay in texture and had varied structure including granular and sub-angular blocky structure. The clay content in soils varied from 2.9 to 59.3 per cent. The clay content increased with depth in all pedons. Silt fraction in the soils 6.9 to 30.7 per cent. The sand content in the soils under investigation varied from 13.9 to 89.3 per cent. Most of the pedons exhibited more or less an increasing trend in bulk density with depth. These soils were near slightly acidic to strongly alkaline in reaction, non-saline and very low to medium in organic carbon. The CEC varied from 1.7 to 44.5 C mol (p+) kg-1 soil and dominated by Ca+2 followed by Mg+2, Na+ and K+. The soils were very low to medium in available nitrogen, low to medium in available phosphorus and potassium. Available zinc was deficient to sufficient in all the horizon. The soils were defficient in available iron, copper and manganese. The soils were classified as Typic Haplusterts, Typic Haplustepts, Vertic Haplustepts and Typic Rhodustalfs.
