I would like to discuss Sea Crop and ormus as an agricultural source of trace minerals. I would like to please stay away from any pseudo-science and keep the discussion to a fertilizer and chemical focus in this thread.
So sea solids are a great source of trace minerals in the garden, right? Sea-90 recommends 1/2 tsp./gal. for foliar, 1 tsp. for soil and 1/2 tsp. for hydroponics. But what about that sodium content?
Ormus is sea salt with a portion of the sodium removed by adjusting the pH and collecting the precipitate. It is what is in the commercial product Sea Crop. It is made by adjusting the pH to 10.78. A precipitate forms and the salt water is removed. The preciptate is dried and used in the same manner as sea solids with dramatically less sodium.
Here are several chemical analyses of different types of Ormus:
Celtic Salt Ormus
Table salt Ormus
It's interesting the table salt contains Silicon Dioxide from the anti-caking agent, but also has a high Aluminum content.
Ormus also contains magenesium oxide, milk of magnesia. If consumed by people, it is a great laxative. For plants, it makes a great magnesium source as a foliar. I am sure kelp contains plenty of sea minerals, which is part of why it is a great biostimulant. I think sea salt and their derivatives definitely have use as trace minerals in the garden.
