Claims27
A method of preparing a trace element solution with a concentration of the metals of at least 90 mg/ml, said method comprising:
- (a) heating water;
- (b) adding manganese carbonate to the water wherein manganese sulphate and sodium carbonate are not used in situ manufacture of the manganese carbonate;
- (c) adding zinc oxide to the water;
- (d) adding copper carbonate to the water to form a liquid mixture;
- (e) adding a dry mixture comprising ethylene diaminotetraacetic acid (EDTA) and/or ethylenediamine-N,N′-disuccinic acid (EDDS) and NaOH to the liquid mixture;
- and
- (f) adding Na2SeO3 to form the trace element solution with a concentration of metals of at least 90 mg/ml,
- wherein the trace element solution has at least 60 mg/ml zinc.
A method of preparing a trace element solution with a concentration of metals being at least 90 mg/ml, said method consisting essentially of the steps of:
- (a) heating water;
- (b) adding manganese carbonate to the water wherein manganese sulphate and sodium carbonate are not used in situ manufacture of the manganese carbonate;
- (c) adding zinc oxide to the water;
- (d) adding copper carbonate to the water to form a liquid mixture;
- (e) adding a dry mixture comprising ethylene diaminotetraacetic acid (EDTA) and/or ethylenediamine-N,N′-disuccinic acid (EDDS) and NaOH to the liquid mixture;
- and
- (f) adding Na2SeO3 to form the trace element solution having at least 90 mg/ml of metals,
- wherein the trace element solution has at least 60 mg/ml zinc.
