Soil physical properties characterisation

 

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

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 250 cm³ soil samples.

For the hydraulic conductivity curve:

  • a pressure cell system to estimate the hydraulic conductivity by the "Multistep Outflow" method.

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

  • the HYPROP system.

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 C.068 (Mendel building). For any information or request for use, please contact Sébastien François.
