In close collaboration with University of Liege, Gembloux Agro-Bio Tech, the Soil Physics Laboratory is trying to develop reference samples that could allow us to cross check our measuring techniques, perform quality controls and detect abnormal discrepancies between devices.

This project gains towards intercomparison of soil physics lab measurements and improve the measurements quality.
Soil physics lab measurements mostly involve undisturbed soil samples. The readings are of course dependent on the soil properties, but they can also be affected by the measurement devices and procedures.
The repeated wetting, drying, heating cycles operated in the soil physics measurements are challenging because the reference samples should remain as stable through time as possible and avoid clogging by microbial development or nanoparticles.
