Influx of CO2 from Soil Incubated Organic Residues at Constant Temperature
Temperature induced CO2 from genotypic residue substances is still less understood. Two types of organic residues (wheat- maize) were incubated at a constant temperature (25°C) to determine the rate and cumulative influx of CO2 in laboratory experiment for 40 days. Further, the effect of surface and...

| description | Temperature induced CO2 from genotypic residue substances is still less understood. Two types of organic residues (wheat- maize) were incubated at a constant temperature (25°C) to determine the rate and cumulative influx of CO2 in laboratory experiment for 40 days. Further, the effect of surface and incorporated crop residues with and without phosphorus addition was also studied. Results revealed that mixing of crop residues increased CO2-C evolution significantly & emission rare was 37% higher than that of control. At constant temperature, soil mixed residues, had higher emission rates CO2-C than the residues superimposed. There was linear correlation of CO2-C influxed for phosphorus levels and residue application ways with entire incubation at constant temperature. The mixing of organic residues to soil enhanced SOC levels and biomass of microbially bound N; however to little degree ammonium (NH4-N) and nitrate NO3-N nitrogen were decreased. |
