Basic Soil CO2-Burst Overview: Solvita CO2-Burst in the new mode is a soil laboratory protocol which measures the flush of CO2 immediately after soil is moistened. CO2-Burst is a special instance of soil microbial respiration due to rapid microbial resuscitation after a disturbance event of dryness followed by rapid re-wetting. It serves as an overall indicator of aerobic soil microbial potential.
Basic Soil CO2-Burst Application: This simple, standardized application requires dried soil to be added by volume to 475mL (1 pint) incubation jars, and then wetted by a specified volumetric protocol and then closed with a CO2-probe inserted for a 24-hr period at fixed temperature.
Results of the CO2-Burst are read with a Solvita Digital Color Reader (DCR) in CO2-Lo mode to attain appropriate quantification as Solvita Color Units and mg/kg CO2-C. By using the new 2019 SOP results obtained by Solvita in this sizing configuration are application from 5 – 225 mg/kg.
