        I skimmed this paper, but it’s interesting.

        One thing to note, is that their salinity (ECs) are good, but not great. Generally, you want them under 2 dS/m in growth media. 3-4 is considered fair, but with some limitations, so they might have to refine their desalinization process a bit more, or you know, use freshwater fish.

        The N input from the fish manure (I feel weird just typing that) is actually pretty good. About 100 lb/ac, which is the upper limit requirement for most crops. They would most certainly need P amendment, though, and that could cause a lot of issue with their aquaculture if it makes its way into the system.

            EC is more closely tied to the presence of metals in soil. Most of the N applied would be in the organic fraction, I’d imagine.

                True. Like I said (or was thinking at least), it’s still a really cool idea, and functional, just needs a bit of refinement to really get going.
