Responses of CH₄ and N₂O fluxes to land-use conversion and fertilization in a typical red soil region of southern China.

ABSTRACT: Land-use conversion and fertilization have been widely reported as important management practices affecting CH₄ and N₂O fluxes; however, few long-term in situ measurements are available after land-use conversion from rice paddies to upland cultivation, especially those including the initial stages after conversion. A 3-year field experiment was conducted in rice paddies and a newly converted citrus orchard to measure CH₄ and N₂O fluxes in response to land-use conversion and fertilization in a red soil region of southern China. Annual CH₄ and N₂O emissions averaged 303.9 kg C ha^-1 and 3.8 kg N ha^-1, respectively, for the rice paddies over three cultivation years. Although annual N₂O emissions
