>>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>
