abstract = {Emission of greenhouse gases from agricultural soils has
main contribution to the climatic change and global warming.
Dynamics of dissolved organic carbon (DOC) and nitrogen
mineralization can affect CO<sub>2</sub> emission from
soils. Influence of DOC and nitrogen mineralization on
CO<sub>2</sub> emissions following lime application to
acidic soil was investigated in current study. Laboratory
experiment was conducted under aerobic conditions with
$25\%$ moisture contents $(66\%$ water-filled pore space) at
25°C in the dark conditions. Different treatments of lime
were applied to acidic soil as follows: CK (control), L (low
rate of lime: 0.2g lime / 100 g soil) and H (high rate of
lime: 0.5g lime / 100g soil). CO<sub>2</sub> emissions were
measured by gas chromatography and dissolved organic carbon,
NH<sub>4</sub><sup>+</sup>-N, NO<sub>3</sub><sup>-</sup>-N
and soil pH were measured during incubation study. Addition
of lime to acidic soil significantly increased the
concentration of DOC and N mineralization rate. Higher
concentrations of DOC and N mineralization, consequently,
increased the CO<sub>2</sub> emissions from lime treated
soils. Cumulative CO<sub>2</sub> emission was $75\%$ and
$71\%$ higher from L and H treatments as compared to CK. The
results of current study suggest that DOC and N
mineralization are critical in controlling gaseous emissions
of CO<sub>2</sub> from acidic soils following lime
