I would like to see more info on using seaweeds as fertilisers for plants that don't grow in salt conditions. IIRC, some Ireland / Scotland place(s) haul it out where it drows like sea weeds, and put it on fields, but they have so much rain the salt is constantly being flushed out down to the rock and back to the ocean. My understanding is (and may be wrong, i dunno) that if they did not use seaweed they would not have any "soil" at all. So i am guessing that they can grow only what can grow on rotting seaweeds, and the veggies grown lack various nutrients. Praps it was only grass that grew on the weeds, and sheep ate that grass, and if the sheep were put on any other grass the sheep died, because their kidneys were tuned over the centuries to having salt to fight against? en.wikipedia.org/wiki/Seaweeden.wikipedia.org/wiki/Algaculture

there's a specific breed of sheep that has adapted to eating primarily seaweed, but seaweed itself has pretty much all the nutrients necessary to fertilize soil. The ocean has all the minerals in it. The build-up of salts is from overspray, more than bringing seaweed on land. Salts don't last forever, under certain conditions they are broken down into constituent minerals and taken up into the chain of life again. When you hear about salination of soils, it's not always sodium chloride- other minerals form salts that make them unavailable to plants as well- like magnesium comes to mind. Addition of soil amendments can help break up the salts in soils and make the minerals into the correct ionic state for uptake.
