Abstract
Eight representative pedons of micro watersheds viz., four near to IWMP Motipura (P1),
Sainiwas (P3), Jhumpa (P5) and Budhsheli (P7) and four few kms away from IWMP Motipura (P2),
Sainiwas (P4), Jhumpa (P6) and Budhsheli (P8) of Jhumpa Kalan Watershed of Bhiwani district, Haryana
were studied for morphological, physico-chemical characteristics and classified as per Soil Taxonomy and
land capability classification and suitability of soils. Soils of the study area varied in colour from dark
brown to dark yellowish brown. The soil texture of pedons varies from sand to loamy sand. The sand
content was higher as compared to silt and clay in most of the pedons. The structure was predominantly
sub-angular blocky in all pedons except pedon 4, 6 and 8 which had granular pedon. The soils were nonsticky
to sticky and non-plastic to plastic consistence. The range of bulk density of different horizons was
1.38 to 1.62 Mg m-3. The available water content varied from 2.04 to 13.78 %. These soils were slightly
alkaline to moderately alkaline in reaction, non-saline (0.02 to 0.24 ds m-1), non-sodic (ESP <15%) except
Ap horizon of pedon 8 having ESP 15.08 %. The CEC varied from 2.21 to 7.85 cmol (P+) kg-1. The
cations Ca2+, Mg2+, K+, Na+ varied from 2.21 to 5.10, 0.20 to 2.90, 0.08 to 0.42, 0.19 to 0.92 (cmol (P+)
kg-1), respectively. Calcium and magnesium were the dominant cations on the exchange complex. The
soils were low in organic carbon and available nitrogen ranged from 0.06 to 0.27 % and 42 to 189 kg ha-1,
respectively in different horizons and decreasing trend was noticed with depth. Soils were low to medium
and low to high in available phosphorus and potassium, respectively. The DTPA-extractable Zn, Fe, Cu
and Mn in mg kg-1 varied from 0.15 to 0.92, 0.87 to 6.49, 1.03 to 4.99, 0.12 to 0.72, respectively. Due to
the presence of ustic/arid soil moisture regime, hyperthermic temperature regime and low organic matter
content, the soils were classified into Typic Torripsamments (Pedon 4 and 8)/ Ustipsamments (Pedon 1
and 2) and Typic Calciorchids (Pedon 7)/ Cambiorchids (Pedon-5). The soils were classified as IIs and
IIIes according to Land Capability Classification. Soils of Pedon-1, 2, 3, 5 and 7 were classified as
marginally suitable class (S3) and almost unsuitable class (N1) of pedon- 4, 6 and 8 according to Soil
Irrigability Classification. The soils of the study area were evaluated according to soil suitability criteria
for different crops and were found suitable (S1) to moderately suitable (S2) for guar, oilseeds (raya),
moderately suitable (S2) to marginally suitable (S3) for pearl millet, gram, forestry and marginally
suitable (S3) for cotton, wheat.
