Was the lawn tested because it had a visual problem?
To me that may indicate that the applications put on top of the surface are still sitting there as P doesn't really move through the soil profile...

Is this interpretation of the raw data trying to say that P is typically more prevalent at the surface and declines a bit every inch down???
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
