    https://agbmps.osu.edu/scenario/soil-test-p-value-less-50-ppm-or-lower-p-risk-assessment

    A soil test that includes a value for Soil Test Phosphorus (STP) is useful to discuss both the risk of yield loss in crop management and as an indicator for risk of environmental loss of P. In crop management, fields with an STP level of less than 20 PPM ...
