Would truckloads of Seaweed help out?

[MrSalvage]

My oldest sister lives in a waterfront community. So i have access to the beach and boat ramps ect. There is always seaweed on the beach and lots of it. I am sure with little effort I could load my 1/2 ton Chevy full and bring it home.

Would that much of the stuff help?

Here is my plan I want to do plastic mulch and drip tape next year. I was thinking of tilling a bunch of rows about 4 ft wide by 100 yds. Say 4 or 5 rows separated by my lawn every 5 foot or so. I would then be able to mow between the rows real easy. The problem is after I till the soil to make it soft and get all the rocks and junk out of it. I have nothing really here to do raised rows. I was thinking that seaweed would help. I know leaves will to but i don't really have much leaf material. I could buy topsoil by the truck load but can see my wallet going broke. With me needed raise rows what would be a cost effective way to do this. I am going totally organic with what I will consider a no till deal after the first time to clean up.

Whaddyathink?
