    "title": "Process of Applying Sea Solids as Fertilizer",
    "inventor_name": "Maynard R. Murray",
    "publication_year": 1963,
    "device_name": "Sea Solids Fertilizer",
    "goal": "Remineralize soils with sea-derived mineral salts to improve plant and animal health, increase crop yields, and enhance nutritional quality.",
    "problem_addressed": "Soil mineral deficiencies that reduce crop productivity, increase disease susceptibility, and lower nutritional value of food.",
    "concept_summary": "Murray's invention extracts the inorganic salts (sea solids) remaining after complete evaporation of seawater (~=3.5 % solids). These minerals, containing the full suite of >90 elements present in seawater, are applied to soils or hydroponic systems in proportions that mirror their natural seawater concentrations. Field and animal feeding trials reported higher yields, earlier maturity, greater disease resistance, and increased vitamin and mineral content in crops and livestock.",

    "experimental_evidence": "In corn experiments (1952-1954) treated plots yielded 13-19.6 bushels more per acre than controls; ash weight increased 1.7 %; soy beans showed 14.6 % higher ash; tomatoes, onions, sweet potatoes had 18.7 %, 4.4 %, and 8.3 % higher ash respectively; chickens on treated feed matured a month earlier and laid eggs 2-3 oz heavier per dozen; rats on treated grain did not develop xerapthaemia.",
