Microbial nitrification, denitrification and respiration in the leached cinnamon soil of the upper basin of Miyun Reservoir.

ABSTRACT: Leached cinnamon soil is the main agricultural soil distributed in the North China Plain. In this research, leached cinnamon soil samples were collected in the upper basin of Miyun Reservoir (northeast of Beijing, China). The BaPS method (Barometric Process Separation) was applied to measure nitrification, denitrification and respiration rates. The rates of nitrification, denitrification and respiration were 0-120.35 μg N/kg SDW h, 0-246.86 μg N/kg SDW h and 0.17-225.85 μg C/kg SDW h (Soil Dry Weight, SDW), respectively. The emission rates of CO₂ and N_xO_y through nitrification, denitrification and respiration were 1.00-547.80 and 6.00-4850.65 μmol/h, respectively. The analysis of relationships between nitrification, denitrification and respiration rates ind
