| Summary: | Abstract The Fertilizer Recommendation Support Tool (FRST) Project is a collaborative effort involving most land grant institutions, USDA branches, nonprofit organizations, and private industry. The FRST objectives are to develop a soil fertility community of practice, preserve soil test correlation and calibration data in a relational database, and develop a decision tool to provide consistent soil test interpretations. Released in April 2024, the interactive tool acts on an evolving database that contained 1455 P trials, 1316 K trials, and 143 S trials from 44 states and Puerto Rico by March 1, 2025. Decision tool outputs include an interactive county‐level map of available data and an estimated critical soil test value. The FRST relational database is a repository for soil‐test‐based P, K, and S data to support data‐driven management recommendations. Continued success of the FRST project and decision tool utility rely on collaboration and support from the soil‐test‐based nutrient management community. |
