I realize that Milorganite is processed sewer sludge (aka biosolids), but not sure if this is the same as the sludge used by farmers as fertilizer. The below article did not mention how the sludge was processed. I'm guessing the sludge mentioned in the article is unprocessed, since it appears to be available from most municipalities.
Does the processing used by Milorganite makers (Milwaukee?) eliminate or at least reduce the heavy metals mentioned in the article? (thallium and others).
I know there have been some heated discussions in the past. Another question - can a farmer use the sludge as fertilizer and still be allowed to use "organic" labeling?
