Better Fertilizer Decisions from Soil Test Calibration Data

Interpretation of soil test values is influenced by the user's perception of the data backing their relationship to observed crop responses. Doubts about such data give rise to suboptimal decisions regarding the source, rate, time and place of nutrient application. The consequences are large, particularly for a nutrient like phosphorus whose management has both economic and environmental impacts. This presentation explores the potential benefits to producer decisions and public perception that might arise through making available a comprehensive online soil test calibration database, using the Australian Better Fertilizer Decisions for Crops initiative as an example.
