Tosefta על ביכורים 1:7

Behold, he separated his first fruits and he recited over them, and then he went back and purchased a different field, and five different species of first fruits had [already] been taken from it. [In that case,] even though he takes from it [fruits] from the same species [as the previous owner], he brings but does not recite, as a person may not recite [the first-fruit declaration] twice in the same year.
