Western Ag Innovations <http://www.westernag.ca/innov/> is offering students the opportunity to receive a credit for up to 50 PRS (Plant Root Simulator)-probe samples (a value of $1870) for use in their research. PRS-probes are an alternative soil analysis tool employing an ion exchange resin membrane to measure net 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. Assessment of the capacity of a soil to supply nutrients is based on absorption of nutrient ions on PRS-probes during a burial period.
