So much for Organic
Doesn't make a lot of sense as to why they'd do it though as one of the main uses is for playgrounds...
Great tip on the pH though, I knew there must be something beneficial to it (for me).
I've also looked at all the washed up kelp on the beach after reading another members post... Most of the "fresh" kelp was swarming with flies though... though maybe the dried out stuff could be considered composted
Either way it didn't seem like the type of stuff I'd wanna throw in the back of the car without at least double bagging it
