• Plant Root Simulator (PRS) probes consist of either cation- or anion-exchange resin membranes encased in a plastic holding device, which are inserted into the soil to measure ion supply in situ with minimal disturbance. 
• The PRS probes simulate the action of plant roots by adsorbing soil nutrient ions through ion-exchange, thereby acting as a nutrient sink. 
•  The PRS probes integrate all of the principal edaphic factors affecting nutrient uptake by plants (i.e., soil moisture and temperature, Mineralization, immobilization, free ion activities, buffer power, ion diffusion, etc.), regardless of soil type.
• In 2005, the PRS probes provided a basis for determining  Fertilizer Recommendations on over 2,000,000 acres of farmland in western Canada for a variety of cereal, oil seed, pulse, and forage crops.
