      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.

        Doesn’t the salinity mainly come from nitrates in this case?

          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.

            Well… we are talking about artificial water logged sand here however.

              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.
