KBS013:Trace Gas Fluxes in Cropped and Successional Communities
Results from a study of N2O and CO2 fluxes from soybean/corn
cropping systems either no-till (NT) or conventionally tilled (CT; moldboard
plow) and either N-fertilized (180 kg/ha N) or not N-fertilized in a complete
factorial design with four replicate blocks (2 × 2 × 4 treatment plots) plus
the never-tilled early successional sites (n = 4 replicates) noted in KBS004.
Fluxes are measured using static chambers 30 cm x 30 cm x 14 cm high placed on
semipermanent bases installed in the surface soil of each plot. Gas samples are
taken from each plot at 15-minute intervals for 90 minutes per sample day, once
per week or keyed to rainfall events.
