Validating tools used to reduce soil phosphorus saturation by monitoring soil tests and phosphorus loads in an intensive livestock region

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.
