Goal
Produce an economical, bio-active fertilizer and nutritional supplement from seawater and similar brines by co-precipitating organic carbon compounds with magnesium and calcium minerals.
Problem
Conventional seawater-based fertilizers contain excessive sodium chloride and lack the synergistic organic-mineral complex needed for optimal plant growth and health.
Concept Summary
Sea-Crop is a concentrated slurry obtained by raising the pH of seawater (or brine) to ~10.8-11.0 with NaOH and adding carbonate (Na2CO3) to precipitate magnesium and calcium hydroxides together with dissolved and particulate organic carbon. The resulting slurry, retaining entrained water, is applied to soil where it enhances microbial activity, root development, fruit size, shelf-life and reduces transplant loss.
Detailed Description
In the patented process (US7261912), seawater is fed into a reaction vessel where caustic soda (NaOH) is added until the hydroxyl ion concentration matches the magnesium ion concentration, achieving a pH of 10.75-11.0. Soda ash (Na2CO3) is added in stoichiometric proportion to calcium ions. The mixture is agitated, causing co-precipitation of magnesium hydroxide, calcium hydroxide, trace minerals, and both dissolved and particulate organic carbon. The precipitate is retained as a slurry (the "Sea-Crop" product) while the supernatant brine is discarded. The slurry is applied to crops, where it promotes micro-flora symbiosis, increases root mass, and improves fruit weight and shelf-life. Reported field observations include a 2.4-fold increase in raspberry berry weight (20.66 g vs 8.53 g) and at least a 50 % reduction in transplant loss for crucifers, melons and peppers.

Replication Status
No independent replication reported; performance data presented only by the inventor/company.
Limitations
- Requires precise pH control and stoichiometric addition of NaOH and Na2CO3
- Performance data limited to company-provided field trials
- Potential scalability challenges for large-scale agricultural use
Red Flags
- Use of vague language such as "catalytic trigger that releases nature's energy"
- Lack of peer-reviewed or independent validation of claimed yield increases
