Abstract
Microcalorimetry was applied to the study of the microbial activity of four soils with different percentages of organic matter. The qualitative study of the heat flow rate-time curves, recorded from soil samples amended with glucose, showed remarkable differences in the soil microbial activity. In order to show results in a more quantitative way, the total heat evolution, Q tot, the total heat evolution of soil samples amended with glucose, Q tot(glc.), and the values of peak time and microbial growth rate constant, μ, were calculated from the heat flow rate-time curves recorded from all samples. Values of peak time increased with decreased microbial density and a positive correlation between total heat evolution, Q tot, and percentage of organic matter, was found. Microcalorimetry appears as a suitable technique to carry out both qualitative and quantitative comparative studies of microbial activity in soils.
