Soil Physical Properties

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.

For the hydraulic conductivity curve :

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

• 3 KSAT units ;

• the HyProp system.

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:
