followed and representative soil sample was collected. The total 200 soil samples
were collected from different land use. The soil sample to the depth of 1 m was
taken using soil screw auger and core sampler was used to collect the soil core at
different depth for estimating the bulk density. SOC was determined using Walkley
and Black rapid titration method (Walkley and Black 1934). The % of SOC value
obtained from the WB method was multiplied by standard correction factor of 1.32
(De Vos et al. 2007) to obtain the corrected SOC.

The results were tested using different statistical techniques such as F-test and
correlation among all samples for the all LULC.
