It should be ok to use, but dried fresh foraged kelp would be better.Thanks man. I figured someone would say something about the proximity of the kelp to boats/water dumps. Definitely something I will stray from. I could also look at tide charts for the area to make my hunt more specific in avoiding those contaminants.
Rotting kelp should be fine for the compost bin right? I'm not eating it. Won't it just rot and break down anyway?
I say this because it will be rotting in anaerobic conditions, then when you add it to your compost pile, it would be the same as adding grass that has sat in a wet pile too long.
When you use grass clippings in a compost pile, it's smart to spred the grass out and let it dry before making it into compost to avoid anaerobic activity. I'm referring to fast/hot composting. The same would apply for kelp.
Pick up the book teaming with microbes, it's a great read.
Most of the info about the breakdown rate of kelp came from the next book "teaming with nutrients" id grab both if you have the chance.
When you find a good hot spot with diverse varieties of kelp on the coast let us know.
I'll talk to a friend of mine who does this and figure out where he likes to go and I'll keep you updated.
