Two pedons exposed each in Badagaon and Rampur villages of Maniyar bock, Ballia district to study the layer-wise distribution of some physical and chemical properties. The sand, silt and clay pedon-1 were varied from 25 to 55 %, 30 to 60 %, clay 8 to 16 % while it was 40 to 65 %, 25 to 45 % and clay 10 to 17 % respectively in pedon 2. Bulk density increased with depth upto 90 cm, water holding capacity decreased with increasing depth in both the pedon, and it ranged from 43.35% to 34.02% through depth. The pH ranged from 6.2 to 7.4 in both the pedons but its distribution with depth different in these pedons. The electrical conductivity of soils in both the soils was above to 1ds-1. The organic carbon content was high in upper layer of depth in soils. Calcium carbonate ranged from 2.5 to 0.4% and 3.9 to 0.4 with depth in soils. Available N, P and S were higher in surface layer and decreased with depths but their values were in higher side in pedon 2 barring few exceptions with soil depth amount of available P content in surface and sub-surface soil. However, it was slightly medium in soils of pedon 2. The medium available K content was found in surface layer (0-15 cm) and decreased with depth in both the pedons. The S content in surface soil was found to be higher than sub-surface soil. The amount of available S was found in surface horizons (0-15 cm) 13.5 mg kg-1 in pedon 1, and 14.2 mg kg-1 in pedon 2. The surface layer of pedon 1 had 13.4 cmol (p+) kg-1 exchangeable Ca while it was 6.4 cmol (p+) kg-1 in P2. The exchangeable magnesium in pedon 1 was 8.2 cmol (p+) kg-1 at 0-15 cm and 3.2 at 135-150 cm while in pedon 2 had exchangeable magnesium 7.3 cmol (p+) kg-1 at 0-15 cm and 3.0 at 135-150 cm soil depth.
