  • Liquid fertilizer solution containing zinc
    Patent number: 4356021
    Abstract: A homogeneous, zinc-containing liquid fertilizer concentrate is prepared by mixing, in aqueous solution, ammonium thiosulfate and zinc oxide. This zinc-containing concentrate is suitable for mixing with a liquid fertilizer preparation such as aqueous ammonium polyphosphate to prepare a complete zinc-containing fertilizer solution. The nutrient value of the concentrate and the fertilizer can be enhanced by the addition of a potassium salt or nitrogen solution. The long-term stability of the fertilizer solution can be improved by the addition of attapulgus clay.
    Type: Grant
    Filed: December 30, 1980
    Date of Patent: October 26, 1982
    Assignee: Phillips Petroleum Company
    Inventor: Joseph R. Kenton
  • Fertilizer solutions stabilized with inorganic acids
    Patent number: 4336053
    Abstract: A stable liquid fertilizer solution containing nitrogen, phosphorus, iron and optionally sulfur is prepared by mixing a water-soluble iron compound with ammonium polyphosphate and water to produce an iron phosphate slurry having a molar ratio of polyphosphate phosphorus to iron of at least about 2:1, adding ammonia to the iron phosphate slurry to produce a solubilized iron complex; and adding an inorganic acid to the iron complex solution. The amount of acid added is generally that which brings the pH of the fertilizer solution to within the range of about 5.5 to 7.0.
