A study of the rate of carbon dioxide output during mineralization of some organic materials in soil.
Soil respiration (CO2-evolution) was measured at different intervals during mineralization of organic materials in an Egyptian clay-loam soil. The rate of CO2 output was found to decline by time, and a linear negative correlation was found between the logarithm of time and the logarithm of the rate of CO2 output. Applying the linear regression equation it was possible to describe this relationship mathematically. A significant positive correlation was also found between the rate of CO2 output and the total plate count of bacteria and the ATP content of the soil.
