Since 1998 Prairie farmers have had available an innovative decision support tool in the PRS™
Technology. Crop nutrition plans are generated that recognize the unique characteristics of the
field’s soil nutrient supply rate and acknowledges the economic risk tolerance of the individual
farmer. Though provincial soil test results are not useful to an individual, the monitoring of
yearly data over time will give indications of “average” soil nutrient supply changes over time.
Year to year differences can also provide the fertilizer industry signals of anticipated demand.
