Quantification of soil hotspots and hot-moments is one of the main challenges to understand the variability encountered in soils in terms of respiration activity and trace gas emissions. At the current state of the art, determination of the link between the biological and soil heterogeneity is a challenge. The latter is also a function of the scale at which the phenomena are observed. However this target is difficult given the lack of instrument to measure spatial variability in bacteria activity at high frequency. In order to fill this gap and to improve the current knowledge, our work aim in studying the temporal evolution of oxygen (O2) consumption maps resulting from the addition of DI water, humic acid and glucose. The overall objective of this study is to investigate the link between the spatial average consumption rate and land use and also to trace spatial variability of O2 for a given time point.
