Soil Physical Properties

ELIE Louvain-La-Neuve

This laboratory has most of the standard instruments to characterise the hydraulic properties of about a hundred soil samples at the same time.

Retention curve

For the retention curve, the following equipment is available :

  • two sandboxes to characterise the retention curve of about 90 soil samples from pF 0 to pF 1.8.

  • six pressure plate extractors for the retention curve between pF 2 and 4.2.

  • a water potential analyser for high pF by psychrometry (WP4C).

  • a 10 cell HyProp system (evaporation method) for 100 & 250 cm³ soil samples.

Hydraulic conductivity curve

For the hydraulic conductivity curve :

  • a permeameter for the saturated hydraulic conductivity. (Closed system - 10 holders)

  • 3 KSAT units ;

  • the HyProp system.

Soil structural stability

QuantiSlake tests can be carried out:

  • 2 soil samples of 100cm³ can be processed at the same time. (Raspberry Pi + Scales)


In addition, the laboratory has several instruments for in situ measurements: pressure & suction infiltrometers, TDR probes, tensiometers, etc. and equipment for soil sampling (Rings of 100, 250, 1000 cm³).

It can be found at B.230 (De Serres building). For any information or request for use, please contact:

  • Olivier Lebbe (Technical manager)
  • Basile Delvoie (Scientific manager)
  • Mathieu Javaux (Academic head)
  • Sébastien François (ELIe technician)
