Complete Set for PF Determination – Sandbox and Pressure Method (PF 0-4.2)

The Complete Set for PF Determination, 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.

With this complete set for PF determination 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.
