They didn't have the means to make it productive land and produce crops, and didn't have the workforce either. Indians living there were nomadic and offered great resistance to Spanish subjugation, the opposite from the tribes living in the centre of Mexico, sedentarian and already used to the dominance of an empire, the Aztec one.
