  • Seaweed NPK and salt limits

    Tried posting this on List of organic N:P:K values....by Nicos without any success

    Due to being a big seaweed user now, thought better look into the salt (sodium)limits

    Link below gives seaweed nutrients, note kelp is lower in sodium if using a lot or on salt sensitive plants
    Seaweed.ie :: Chemical composition

    Below is table (on page 5 + 6) of vegetable, fruit trees, nut trees, etc salt sensitivity

    By my workings, very happy to be corrected
    1dsm is 550ppm so at 30cm deep a 1 metre square area can have 165cm3 of salt
    Taking worst seaweed at 3.5% then get 4714cm3 seaweed
    So in theory a sensitive strawberry is ok to have up to about 4.7kg m2 of bladder seaweed. Can double that for kelp and more if high rainfall as sodium is mobile and washes out soils. On other hand if not mixing in 30cm then needs reducing.
    I have not put any on sensitive 1.0 crops (Strawberry, Raspberry, etc) yet but may well start
