Bill,
That sounds serious. The place where I buy mine has a "contents" sheet to
read before you buy. The ingredients are mostly organic - such as horse
manure, chicken manure, composted straw, peat moss, cottonseed meal, soybean
meal, gypsum, urea, ammonium nitrate, leaf mold, dolomite lime to raise the
pH to about 7 and heat sterilized. I know it is tested for pesticide
residue and heavy metals also. I have been using mushroom compost one year
and composted recycled yard debris the next, so hopefully I won't get the
salts build up. Thanks for the warning!

Marilyn,
I used mushroom compost for several years and it seemed like wonderful
stuff.
I had Victory Garden soil from it! Then I started having problems.
Daffodils
died, chickweed proliferated. A horticulturalist at Spring Grove Cemetery
here in Cincinnati told me they routinely send all soil additives for
testing
before they use them and their last batch of mushroom compost tested as so
full of salts that it should not be used for plant material. I'm now very
wary of mushroom compost.
