Soil organic carbon influences soil physical and chemical processes, and serves
as repository source of plant nutrients. Limited information is available
concerning SOC status in the Nepalese soils. Two hundred soil samples from five
different soil depths of Rampur
and Baireni, were analyzed to evaluate the precision of loss on ignition method
of SOC analysis. The SOC values obtained were compared with SOC values from dry
combustion method of SOC analysis for the same soil samples. The correlation and
regression showed precise result of SOC from both locations of the experiment.
The coefficient of regression for Rampur and Baireni soils were 0.80 and 0.73
respectively. The regression lines were close to 1: 1 line. |
