Mushroom compost

Mary Sue referred to using mushroom compost one year with disastrous  
results. I used to build whole beds with it, mixing it with our native clay  soil. It 
added wondrous tilth. About three years after the first bed, every  daffodil 
planted in it was gone. 
Another year, the daffodils didn't even come up the first spring in a new  
bed with mushroom compost.
The horticulture head at our huge Spring Grove Cemetery here in Cincinnati  
told me that when they add soil amendments, they always send samples to a lab  
for analysis first. He had a batch of mushroom compost that came back with the 
 analysis that it was so full of salts it would not support plant life.
Of course I no longer use mushroom compost.
