I thought I would pick this group's brains regarding 8.3 pH municipal compost. If you google "ann arbor compost analysis" the first link is a PDF with the results. It is not a typo, as in past years the results were 8.2 and 8.3 (on page 2).
I get one c.y. at a time (the first one is free) and use the compost for seed starting, mostly with success although IMHO tomatoes do not really thrive in it (I assume it is the pH and add some peat moss and Miracid in the mix). My questions:
1) what causes the pH to be so high? AFAIK the City uses only city waste, that is leaves, grass clippings, and chipped branches. Visually, it looks to be just that. Let me mention that I have an idea, but I will wait to see a few replies.
2) what do you think of the cadmium content (page 1)?
