Perhaps you might want to conduct a search on pig and poultry manure as it applies to phosphorus pollution.
This is an interesting thought experiment that introduces a lot of confounding factors. Maybe we could add to this research conclusions from several universities that found more P in runoff water from unfertilized soils than soils where P was added at 10# actual P/M for successive years.

Research has shown us that P doesn't move quite like other nutrients move and that mass flow doesn't have the same effect on P as it does on other nutrients.

There's a reason Auburn's Beth Guertal calls P "nature's slow release fertilizer."
