Determine data type of empty NotesItem?

I want to determine the type of a NotesItem that contains no data. However, for text, numeric and date fields, the Type property always returns a type of STRING when the item is empty. How is it possible to determine the real type in this case?

There is no real data type in the sense you mean. Imagine two forms, Form A with the field MyDataField as a numeric field, and Form B with the field MyDataField as a date/time. This is perfectly valid, although it is likely to lead to trouble eventually. The empty item can be set to a number or date or string or whatever. So, the best you can do is find out the data type of the field on the form, not the item on the note.
