From burnt soils to mountain soils?

It is within the European project IRISE (Impact of Fire Repetition on the Environment) that Lauric Cécilion has developed the near-infrared spectrometry soil carbon measurement method. Like agricultural soils and mountain soils, burnt soils are threatened by a drop in their stock of organic matter. This tool can measure the impact of the repetition of the fires on the soil quality. The researcher has also shown that the spectrometric analysis of earthworm castings makes it possible to select the plots based on how long ago fires occurred. Finally, the technique made it possible to validate the positive action of earthworms on the build-up of organic carbon and nitrogen and the richness of the microbial flora in the soils after burning.
