Measurements of Soil Carbon Dioxide Emissions from Two Maize Agroecosystems at Harvest under Different Tillage Conditions

Figure 3

Six consecutive days of soil CO₂ flux measurements in the two experimental sites. Each point represents the average of the fluxes measured by all the chambers of the SASSFLUX system at each site (3 chambers at NT site and 4 chambers at CT site) in a 15 min period. Vertical bars indicate the standard deviation of the chambers measurements in each 15 min period (CT = conventional tillage site; NT = no-tillage site). Points without vertical bars refer to 15 min periods in which only one chamber was running.
