Description

For research of water availability in the soil for plants and trees, the determination of the moisture characteristic (pF-curve or soil retention curve) of the soil is essential.

This full set consists of: 

Sandbox for pF-determination 0 - 2.0 for a maximum of 40 soil sample rings

Sand-/kaolin box for pF-determination 2.0 - 2.7 for a maximum of 40 soil sample rings

Membrane apparatus for pF-determination 3.0 - 4.2 for a maximum of 15 soil sample rings, including compressor and accessories

Soil sampling set with rings of 53 mm in diameter

Additional soil sample (copecky) rings

Soil sample (transport) boxes

With this set you have the instruments needed to take undisturbed samples in the field and determine the complete soil retention (pF) curve. But, please note that a precision balance and drying oven are also required for testing in the lab.

Up to 40 samples can be tested per sandbox, which allows for large scale research and the determination of a representative and effective average.

A functioning sandbox can be used for several years if the sand/ sand-kaolin is kept inundated with water after each test. A copper ring helps to prevent algal growth.
