Five representative pedons were selected based on Image interpretation (IRS
LISS-III) to characterize the salt affected soils of district Chittorgarh, Rajasthan. Soil
samples were collected at an interval of 15 cm to a depth upto 90 cm. The soils were
sandy clay loam to clay loam in texture, sub-angular blocky to massive in structure
and calcareous sodic in nature. The sodicity and calcareousness increased with depth
of the pedons examined. Further, the clay content was higher in substratum, leading
to an increased CEC values indicating a main contributor, since the organic carbon
content of the soils under study is low. Among soluble ions Na+ and Cl-
dominated
followed by Ca+2 and HCO3
-
in the saturation extract. Calcium and sodium are the major
contributing exchangeable cations followed by magnesium. Two pedons (P1-Bhopalsagar
and P2-Tana) of tehsil Kapasin categorized under slight to moderate, while three pedons
(P3-Kanakhera, P4-Dungla and P5-Idra) of tehsil Rashmi and Dungla under moderate to
highly sodic category requiring proper reclamation as well as management alternatives
for sustainable crop production.
