FRST Decision Support Tool Feedback
The Google Form link below connects to a feedback form where you can provide comments after using the FRST decision support tool. Your feedback will help guide and prioritize tool revisions. Keep in mind, the FRST tool aims to provide a critical soil test value (CSTV) for phosphorus or potassium by fitting a quadratic plateau model to crop relative yield response data. Data to determine CSTV has been collected from past fertility trials and is stored in a national database. As new trials are conducted, data from those trials will be added to the database. For some crops and soil test methods, fitting may not be possible do to limited or no data.
