Thats the stuff that we have used on reseeds for years. But obviously not enough.Oh... that stuff, don't quote me because I can't remember but I seem to remember that stuff is pretty insoluble being rock phosphate. I can only remember using it on an organic place? Might be wrong mind.
Whats the difference between scotphos and tsp?
