Wow, this is exactly opposite from what I've heard.  I've heard that
bearded irises do NOT want to have a lot of organic matter in their soil
-- that they will then rot.  So I can see the lime, superphosphate,
chemical based 13-13-13, gypsum, and potash, but the sewage sludge?
maybe down in the very very very bottom!

Am I doing something wrong here?  I have my BI's planted in the most
inorganic soil I have.  I top dress with alfalfa, super phosphate, and
cedar flake mulch (the lightest mulch I can use -- otherwise I get
weeds, too much and I get rot).  The cedar flake does raise the pH a bit
but not much -- we have VERY alkaline soil and irrigation water here.
