Patent number: 10183075Abstract: The invention discloses a trace element solution, which comprises at least one metal selected from the group comprising selenium, copper, zinc, manganese and chromium and which comprises a concentration of the metal(s) of at least 60 mg/ml. The solution further comprises at least one compound selected from the group comprising iodine, potassium iodide, sodium iodide, iron, iron chloride, zinc oxide, manganese sulphate, sodium selenite, copper carbonate, sodium carbonate, anhydrous disodium EDTA and sodium hydroxide. The trace element solution is prepared by a method consisting essentially of the steps of preparing a MnCO3 mixture in a container; adding an EDTA/NaOH mixture to the container and subsequently adding at least one metal compound; and adding Na2SeO3 to the container to obtain the trace element solution. The method also comprises the step of adding CrCl3.6H2O to the trace element solution.Type: GrantFiled: September 26, 2007Date of Patent: January 22, 2019Assignee: WARBURTON TECHNOLOGY LIMITEDInventors: Robert Naylor Laurie, William Alfred Smith
