Trace elements
A method of preparing a trace element solution includes the steps of providing at least one EDTA-complex, providing a sodium selenite solution, and combining the EDTA-complex(es) and the sodium selenite solution to form a trace element solution. An EDTA complex is prepared by using disodium EDTA or EDTA acid, selenium, and any other suitable mineral.
