    Physical Characterization of Soils of Barhu Village Under Jumar Nala Watershed
    (Birsa Agricultural University, Ranchi, 1995) Ashok Kumar Baxla; R.Kumar
    Physical characterization of soils of Barhu village under different soil series in the Jumar Nala watershed was done to provide the guidelines in terms of physical environment of soil for better planning of the watershed area.Soil represent by various mapping units (BUhB1,BAhB1, BAhC1,NiB2,NcB2 and KOiB2) under Bukur, Barhu, Nagri and Kokdoro soil series at three land situation (upland ,medium and lowland ) indicated that lowland soils represented by ,mapping unit BuhB1 under Bukru soil series had relatively higher clay content (30 per cent ) and were better in properties related to colloidal activities. On the other hand , upland soils represented by mapping units NiB2,,NcB2 and KOiB2 under nagri and kokdoro soils series were dominant in sand content (around 60 per cent ) and possessed properties related to coarser soil particles. Medium land soils represented by mapping units BAhB1 and BAhc1 under Barhu soil series , however were intermediate in all these soil properties. The aggregation status and available soil moisture storage capacity were found better in 30-60 cm soil horizon than that in surface (0-15cm) and surface (15-30cm) layers The total porosity was found to be around 45 per cent in all the cases. The values increased down the depth of soil depending of the clay content. Aeration porosity in all the cases varied between 11 and 13 per cent which are well above the critical value of 10 per cent below which the root proliferation is adversely affected (Baver,1935). All the soil were acidic in nature (ph varying between 4.6 and5.8 ) and had low organic carbon content (varying from 0.32 to .45 per cent).
