In Situ Persistence and Migration of Biochar Carbon and Its Impact on Native Carbon Emission in Contrasting Soils under Managed Temperate Pastures
Fig 1
Total daily CO2-C emission and biochar-C mineralisation rates in the biochar-amended and control Arenosol, Cambisol and Ferralsol.
The bottom two panels includes soil temperature at 5-cm depth, volumetric soil water content at 0−10-cm depth, mean air temperature (an average of maximum and minimum) and rainfall over the 12 months at the Cobbitty field site in New South Wales and at the Elliot site in Tasmania. The weather data were downloaded from the nearest weather station at the Camden airport (http://www.bom.gov.au/) and University of Tasmania (http://console.weatherdata.com.au/index.html). The symbols of biochar-amended and non-amended (control) micro-plots are filled and empty circles, respectively. Error bars are ± standard errors (n = 4).
