Abstract
The nine soil profiles from various micro-watersheds viz., Dadupur Jattan (P1), Kot Sarkari (P2), Dhakwala (P3), Fakir Majra (P4), Fatehgarh forest (P5), Yara forest (P6), Arjun Majra (P7), Kot Mushtarka (P8) and Mahab Aliwala (P9) of Chhachhrauli block were exposed and their morphological, physico-chemical characteristics were studied and classified as per Soil Taxonomy and land capability classification and suitability of soils. The colour of soil pedons was found yellowish brown with dominant hue to 10YR. The structure of the studied pedons were weak to strong, fine to medium, sub angular blocky. The consistency of different pedons varied from non-sticky non-plastic to sticky plastic. The texture of soil pedons varied from sand to loam with sand proportion higher than clay in all the pedons. Bulk density of all the pedons varied from 1.07 to 1.75 Mg m-3 and particle density ranged from 2.50 to 2.65 Mg m-3. The available water content varied from 1.73 to 16.6 %. Soil reaction of the pedons varied from acidic to moderately alkaline (pH - 4.20 to 8.5) and soil were non-saline with EC varying from 0.03 to 0.23 ds m-1. The CEC, ESP and BSP ranged from 1.20 to 15.01 cmol (p+) kg-1, 2.54 to 50.26 % and 42.14 to 97.12%, respectively. The exchangeable cations Ca2+, Mg2+, K+, and Na+ varied from 0.14 to 11.00, 0.16 to 2.50, 0.12 to 0.85 and 0.17 to 3.56 (cmol (P+) kg-1), with calcium and mangnesium being the dominant cations. The organic carbon and available nitrogen decreases with depth and was found low in all pedons and varied from 0.06 to 2.34 % and 62 to 243 kg ha-1 respectively. While available phosphorus and potassium were low to medium and varied from 4 to 20 kg ha-1 and 19 to 300 kg ha-1. The DTPA-extractable Zn, Fe, Cu and Mn in mg kg-1 varied from 0.05 to 0.95, 0.12 to 8.11, 0.02 to 1.60, and 0.11 to 5.27, respectively. The soils of the area were classified according to Soil Taxonomy as Sandy, Mixed, Hyperthermic, Typic Ustipsamments (Pedon 1), Fine loamy Ustocrepts (Pedon-2, 3, 5, 6, 7, 8 and 9) and Coarse loamy Ustorthents (Pedon-4). The soils of pedons were classified as Is (Pedon-4), IIes (Pedon-6), IIs (Pedon-3, 8, 9) and IIIes (Pedon-1, 2, 5, 6, 7) according to Land Capability Classification. According to Soil Irrigability Classification soils of Pedon-1, 2, 4, 6, 7, 8 and 9 were classified as moderately suitable class (S2s), pedon 3 was classified as highly to moderately suitable class (S1s/S2s) and marginally suitable class (S3d) for pedon 5. The soils of the study area according to soil suitability criteria for different crops were found suitable (S1) for Wheat and Maize, moderately suitable (S2) for Sugarcane, Oilseed, vegetable, horticulture and marginally suitable (S3) for paddy.
