Phosphorus sources for organic agriculture (RELACS Practice Abstract)
On many organic farms, especially those without livestock, phosphorus (P) exports through the sale of produce is greater than P imports through fertilisers and purchased animal feed. While soil P reserves from residual fertiliser applied before conversion to organic farming can often deliver P for decades, mining of soils is unsustainable in the long term.
