You might find a difference if the osmotic potential of the soil matrix 
changes sufficiently with the addition of fertilizer.  If you can find an 
osmometer, you can measure the osmotic potential or water potential of 
soil with different amounts of fertilizer added (of course it has to be 
in solution) and then find that treatment that prevents seed 
germination.  Alternately you can try PEG>
