Michael,
Interesting comparison of notes. I wonder if geographical regions &
difference possibly in materials which comprise the compost could be a
factor? My home made materials test somewhat lower than the commercial
blends around 7.6 to 7.8 vs. up to 8.3 with the commercial products. The
tests I reviewed indicate the more aged commercial compost actually have a
higher pH than those leaning to the somewhat green side. Perhaps other
additives used to balance the product. I think I will call and pose this
question to my supplier!
Regards
Chris Andersen
