Yes.

kimmsr, do i need to rinse the salt out of it i will be using it on my vegatable garden.

Can you send some my way?

You do not need to rinse it. It's slippery, though, very slippery, in areas you have to traverse.

Very lucky!!! I live by lake Erie and was going to harvest algae,etc, but that don't compare to the ocean! Anyways this is the best video inever seen about growing food as well as mulching, the principles are based on mulching.. To the right of the page there is a free video, take your time and watch it, you willt thank me later! Send some kelp my way!

Goodluck,
Joe

Some sources recommend rinsing seaweed from salt water sources while others say it matters not. I would suspect that if the seaweed was gathered after a rain it would not have enough salt to do harm, and if dried some any salt would probably not be of concern.
Seaweed from Lake Erie might not be something anyone would want to use because apparently the level of pollution in that lake is rising, again.
