4. What is the PRS™-probe?

The PRS™-probe is an alternative soil analysis tool employing an ion exchange resin membrane to develop a picture of dynamic ion flux in soil and other heterogeneous media. When chemically pre-treated, the anion and cation exchange resin membranes exhibit surface characteristics and nutrient sorption phenomena that closely resemble a plant root surface. When buried in soil, the PRS™-probe can assess nutrient supply rates by continuously adsorbing charged ionic species over the burial period.
