    Hi @tarek_hamida21, thanks for your question! Many times the process involves fermentation (seaweed is soaked in water over an extended period of time, and any remaining seaweed mass is removed, leaving a concentrated liquid). Some companies are drying seaweed, grinding it, and subsequently applying it to soil. For more information, you can also check out this paper, which contains an analysis of different preparation techniques for liquid seaweed fertilizer. Hope this is a helpful start, feel free to reach out with follow up questions!

    @tarek_hamida21 It depends on the species, the level of scientific rigour you apply to product formulation, and whether you mean biostimulant or fertilizer. Biostimulant is essentially 'seaweed sap' and is mechanically extracted or extracted after treating with an alkali; however, to make it market ready you will probably need to tweak the formulation for efficacy and to meet market regulations.
    To turn seaweed into fertilizer, you can simply dessicate and grind it into powder, or increase the bioactives through fermentation and creating concentrated liquid extract. But this varies across species.

    @tarek_hamida21 I use the Johnson-su composting method. the addition of seaweed to the pile 1/2's the time it takes for a finished product. I use fresh bull kelp. The biological activity and mycorrhizal dominance eclipses my piles without the addition of seaweed. Its easy, cheap and you can use a wide variety of organic materials. I use wood chips, horse manure, fish carcasses, crabshells and kelp.
