involved in a thread a few months ago concerning the toxic metals in
Milorganite. If you go to the link Judy Bygd posted on fertilizers recently you
will find that Milorganite is very high in heavy metals. If your soil were
100% Milorganite in Washington state your arsenic level would be at the state
threshold for a toxic waste site. Your lead level would be at 50% of the state
level for a toxic waste site. If you look at the abundance of other fertilizers
available and listed at this great web site you will find that there are
hundreds of other fertilizers that do not contain anywhere close to these
levels of toxic metals.
sure you will find almost all municipal waste sewage sludge contains similar
levels of toxic metals. I am a member of the Delaware Association of Composters
and I can tell you that there is a huge push to get consumer acceptance to using
these waste products in their yards and gardens. Some of these fertilizers
contain waste products from various sources that cost huge amounts to
dispose. The companies get paid for taking the raw materials that go into their
products in many cases. We have a huge coal burning electricity producer in our
area that has a member on the board of DAC. His goal is to get coal ash that
contains large amounts of mercury into our composting stream. Guess what? He has
been successful. It it's undiluted form this ash is a toxic waste. Mixed with
compost and sewage sludge it meets state standards for sale to
important to note that all states in the USA have waste products that cost lots
to get rid of. Some of these people are also involved in setting the standards
for what can be sold as compost.
Needless to say, I am not that popular at some of these

The following site may be of interest to those of you who
fertilize your lawns. It helped me determine which of two brands of
fertilizer to purchase for fall application. One, a very
popular brand, had quite toxic levels of arsenic, while the other had
