Soil CO2 was studied in the Moravian Karst (Czech Republic). It was found that the CO2 concentration in soil pores depends inversely on pore dimension. The simplified relation between soil drill-hole diameter and measured CO2 concentration. cCO20 = (cCO2 - b D)/(1+a D). https://www.markbroyard.com/limited-time-depileve-easy-clean-wax-warmer-cleaner-220-ml-discount-top-mega/
