[USCC] Compost Maturity Index, EPA Posting

[Will Brinton]

Hello Compost World:

Thanks to discussions on this listserve, the US EPA has recently posted, the
former CCQC report "Compost Maturity Index", a result of the subcommittee
on testing methods, and Dr. Buchanan's follow-on study for CIWMB, 
regarding field crop
yield response to compost based on the maturity index system.

The reports are available under the EPA compost web page - 
www.epa.gov/compost
and specifically at:  www.epa.gov/epaoswer/non-hw/composting/pubs.htm

I believe it is time to considering updating the MI by tightening some 
of the nutrient/biological
indicators. If anyone is interested in this, please post a message to 
this listserve.

Thank you.
